All rights reserved. is a registered trademark of Richtek Technology Corporation.Applications InformationThe RT8525 is a wide input operating voltage range step up controller. High voltage output and large output current are feasible by using an external N-MOSFET. The protection functions include output over voltage, output under voltage, over temperature and current limiting protection.Boost Output Voltage SettingThe regulated output voltage is set by an external resistor divider according to the following equation :⎛⎞×⎜⎟⎝⎠FB1OUT FB FB FB2R V = V 1+, where V = 1.25V (typ.)R The recommended value of R FB2 should be at least 1k Ωfor saving sacrificing. Moreover, placing the resistor divider as close as possible to the chip can reduce noise sensitivity.Boost Switching FrequencyThe RT8525 boost driver switching frequency is able to be adjusted by a resistor R SW ranging from 18k Ω to 220k Ω. The following figure illustrates the corresponding switching frequency within the resistor range.Figure 1. Boost Switching FrequencySwitching Frequency vs. R SW0100200300400500600050100150200250R SW (k ) f S W (k H z )ΩBoost Loop CompensationThe voltage feedback loop can be compensated by anexternal compensation network consisted of R C , C C1 and C C2. Choose R C to set high frequency gain for fast transient response. Select C C1 and C C2 to set the zero and pole to maintain loop stability. For typical application,V IN = 24V, V OUT = 50V, C OUT = 100μF x 2, L1 = 33μH,while the recommended value for compensation is as follows : R C = 33k Ω, C C1 = 27nF.Soft-StartThe soft-start of the RT8525 can be achieved by connecting a capacitor from the SS pin to GND. The built-in soft-start circuit reduces the start-up current spike and output voltage overshoot. The external capacitor charged by an internal 4μA constant charging current determines the soft-start time. The SS pin limits the rising rate of the COMP pin voltage and thereby limits the peak switch current.The soft-start interval is set by the soft-start capacitor according to the following equation :≅××5SS SS t C 510A typical value for the soft-start capacitor is 0.33μF. The soft-start capacitor is discharged when EN voltage falls below its threshold after shutdown delay or UVLO occurs.Slope Compensation and Current LimitingA slope compensation is applied to avoid sub-harmonic oscillation in current-mode control. The slope compensation voltage is generated by the internal ramp current flow through a slope compensation resistor R SLP .The inductor current is sensed by the sensing resistor R S . Both of them are added and presented on the ISW pin. The internal ramp current is rising linearly form zero at the beginning of each switching cycle to 50μA in maximum on-time of each cycle. The slope compensation resistor R SLP can be calculated by the following equation :where R S is current sensing resistor, L is inductor value,and f SW is boost switching frequency.The current flow through inductor during charging period is detected by a sensing resistor R S . Besides, the slope compensation voltage also attributes magnitude to ISW.As the voltage at the ISW pin is over 0.4V, the DRV will be pulled low and turn off the external N-MOSFET. So that the inductor will be forced to leave charging stage and enter discharging stage to prevent over current. The current limiting can be calculated by the following equation:()−××××OUT IN SSLP SW V V R R >2L 50μf7RT8525DS8525-01 March 2012©Copyright 2012 Richtek Technology Corporation.

The VDC regulator in the RT8525 has a fixed output current limit to protect the IC and provide 12V DRV voltage for N-MOSFET switch gate driver.()×−×××2OUT SW OUTD 1D V L =2f I Inductor SelectionThe boundary value of the inductance L between Discontinuous Conduction Mode (DCM) and Continuous Conduction Mode (CCM) can be approximated by the following equation :Figure 2.

With an inductance greater than L, the converter operates in CCM at the minimum input voltage and may transit to DCM at higher voltages. The inductor must be−××MAX SLP S L, PK0.4D R 50μR <I be under 0.25V. Then the protection function will perform action 2 to turn off the driver. When protection function is released, the RT8525 will re-start.On the other hand, if the triggered protection is OOVP ,the voltage at node A will be decided by voltage divider composed of R FLT and the internal 8k Ω resistor. This voltage must be designed between 0.25V and 1.25V by choosing R FLT appropriately. Once the OOVP turns on the Switch 2, the divided FAULT voltage will activate action 1to turn off the driver without resetting soft-start. Therefore,when protection function OOVP is released, the RT8525will be in normal operation.where R OVP1 and R OVP2 are the voltage divider connected to the OOVP pin.Fault ProtectionThe FAULT pin will be pulled low once a protection is triggered, and a suitable pulled-high R FLT is required. The suggested R FLT is 100k Ω if the pulled-high voltage was 12V. The following figure illustrates the fault protection function block. If one of the OUVP and OTP occurs, the switch 1 will be turned on, and the voltage at node A will8RT8525DS8525-01 March 2012©Copyright 2012 Richtek Technology Corporation.

The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula :P D(MAX) = (T J(MAX) − T A ) / θJAwhere T J(MAX) is the maximum junction temperature, T A is the ambient temperature, and θJA is the junction to ambient thermal resistance.For recommended operating condition specifications, the maximum junction temperature is 125°C. The junction to ambient thermal resistance, θJA , is layout dependent. For SOP-14 packages, the thermal resistance, θJA , is 100°C/W on a standard JEDEC 51-3 single-layer thermal test board. The maximum power dissipation at T A = 25°C can be calculated by the following formula :P D(MAX) = (125°C − 25°C) / (100°C/W) = 1.000W for SOP-14 packageThe maximum power dissipation depends on the operating ambient temperature for fixed T J(MAX) and thermal resistance, θJA . The derating curve in Figure 4 allows the designer to see the effect of rising ambient temperature on the maximum power dissipation.×××+××ηOUT OUT LPK INV I VIN D TI = V 2L where η is the efficiency of the power converter.⎡⎤⎛⎞⎛⎞×+Δ−+−Δ−×⎜⎟⎜⎟⎢⎥⎝⎠⎝⎠⎣⎦××ΔININ L OUT IN L OUT OUT OUT OUT1SWV 111Q = I I I I I I 222V 1 = C V f where f SW is the switching frequency, and ΔI L is the inductor ripple current.

The Output Ripple Voltage without theContribution of ESR Diode SelectionSchottky diodes are recommended for most applicationsbecause of their fast recovery time and low forward voltage.The power dissipation, reverse voltage rating and pulsating peak current are the important parameters for Schottky diode selection. Make sure that the diode's peak current rating exceeds I LPK , and reverse voltage rating exceeds the maximum output voltage.Capacitor SelectionOutput ripple voltage is an important index for estimating the performance. This portion consists of two parts, one is the product of input current and ESR of output capacitor,another part is formed by charging and discharging process of output capacitor. Refer to figure 3, evaluate ΔV OUT1 by ideal energy equalization. According to the definition of Q, the Q value can be calculated as following equation :selected with a saturated current rating greater than the peak current provided by the following equation :9RT8525DS8525-01 March 2012©Copyright 2012 Richtek Technology Corporation.

The following layout guides should be strictly followed for best performance of the RT8525.`The power components L 1, D 1, C IN , C OUT , M 1 and R S must be placed as close as possible to reduce current loop. The PCB trace between power components must be as short and wide as possible.`Place components R FB1, R FB2, R OVP1 and R OVP2 close to IC as possible. The trace should be kept away from the power loops and shielded with a ground trace to prevent any noise coupling.`The compensation circuit should be kept away from the power loops and should be shielded with a ground trace to prevent any noise coupling. Place the compensation components to the COMP pin as close as possible, no matter the compensation is R C , C C1 or C C2.Figure 5. PCB Layout GuideFigure 4.

This supply should deliver either 5V-15V or 12V-27V depending on the model of boost converter fitted.For Type 1 (IEEE802.3af) applications the EvalAg7x61 can be fitted with an Ag7200 isolated boost converter for a maximum power output of 20W. With the Ag7200 fitted the EvalAg7x61 should be supplied with a DC Power supply of 5V-15VFor Type 2 (IEEE802.3at) applications the EvalAg7x61 can be fitted with an Ag7100 isolated boost converter for a maximum power output of 40W. With the Ag7100 fitted the EvalAg7x61 should be supplied with a DC Power supply of 12V-27VAdditionally, the EvalAg7x61 can be supplied from an auxiliary DC Power supply delivering between 44V and 57V to J4.Both DC jack connectors J3 and J4 are configured with the positive supply connected to the centre pin and 0V to the outer ring.DC/DC AdjustThe output voltage of the Boost module can be adjusted by moving the jumper on DC/DC Adjust headers between LK7 and LK8. Placing the Jumper on LK8 will result in the output of the DC/DC converter being set to 48V. Removing the jumper from LK8 and inserting it on LK7 will result in the DC/DC converter outputting 57V.If a different voltage is required, please contact Silvertel for more details.DataA data source can be connected to the Data port J100 via RJ45 connector. This data will be transposed onto the Data and Power output port J101 via the data transformer. The data traces on the evaluation board have been designed to pass through10/100/1000/10GBASE-T Ethernet data signals. No processing or amplification of this signal will be performed on the evaluation board6 Auxiliary SupplyThe Auxiliary supply port, J4, can be used to either inject a secondary supply for theAg6120 or as an output so that the fitted DC/DC converter can be used to power external devices.If J4 is used as an output, it is important to remember that there is an OR-ing diode fitted to the EvalAg7x61, so there will be a voltage drop on the output of the Boost converter.7 PSE OutputPower option selectThe Ag6120 has an option to select its output power and class. These can be chosen by placing a jumper on the appropriate pins of LK6. The power option select should be set while the Ag6120 is powered off, if the power option is changed while the device is powered, the change will not occur until after the Ag6120 output has been power cycled.Mode Classificationtype*2Maxoutputpower*3Connectedpair sets*4Legacy Type 2 (at)*1 IEEE802.3at 38W Either 2Type 1 (af) IEEE802.3bt 20W Either 2Type 2 (at) IEEE802.3bt 38W Either 2 Legacy high power at + legacy class 5 75W All 4BT 1 pair (bt class 5)*5 IEEE802.3bt 46W Either 2/all 4BT Type 3 (bt class 6)*5IEEE802.3bt 75W All 4Table 1: option selections and limits*1 Not recommend for new designs only for use as drop in replacement of the Ag6100*2 See section 5.5.2: Classification of the Ag6120 Datasheet for details*3 See sections 5.7: Output Current Limits & 5.8: Output Power of the Ag6120 Datasheet for details*4 See section 5.4: Port Output of the Ag6120 Datasheet for details*5 Compatible with IEEE802.3bt single signature PDsPairset SelectThe EvalAg7x61 contains four links LK1-4 that connect the pairsets to the outputs of the Ag6120. In order to enable power transfer down a given pairset a jumper should be inserted onto the relevant link or removed if power is not desired down that given pairset. Pairsets 1-2 and 4-5 are connected to the positive output of the Ag6120. While pairsets 3-6 and 7-8 are connected to the negative output of the Ag6120. In high power modes all four jumpers should be fitted.When only two pairsets are to be connected, in order to guarantee operation either pairsets 1-2 & 3-6 should be connected or pairsets 4-5 & 7-8 should be connected.OperationTo ensure that the Ag6120 does not apply power to a non-PoE enabled device the output port first checks for a valid PoE signature. If the Ag6120 does not see a valid signature then it will disconnect, wait approximately 2 seconds then try again. Once a valid signature has been detected the Ag6120 will then perform classification to determine the power requirement of the PD, only after this has occurred will the Ag6120 supply power to the powered device.Status OutputThe Status LED will illuminate if the Ag6120 is providing power to the output port. It will also flash as per the table below when an error has occurred. If this functionality is not desired, it can be disabled by removing the jumper on link LK5.Fault Condition Status Pulses (200ms)Short Circuit 1 x FlashOver Current 2 x FlashesSignature/Class Error 3 x FlashesInput Voltage < UVLO limit 4 x FlashesTable 2: Status Output8 Test SetupFigure 2 shows the basic set up using the EvalAg7x61 evaluation board fitted with anAg6120 and Ag7100 for a Type 2 PSE setup capable of supplying the application with up to 40W of power.

Please take some time to read this document to allow you to get the most out of your purchase and familiarize yourself with the features available in the unit.Physical connectors1. LED Indicator2. 1Gb Ethernet (Power over Ethernet)3. HDMI Input4. HDMI Output5. Audio Headset connector6. DC Input (5-18v DC)7. Reset SwitchPowering MiniMini is equipped with a sophisticated system allowing power from various sources:PoE (Power over Ethernet)PoE is a convenient way to power Mini as it allows both data and power to be sent through the same standard Ethernet cable. To take advantage of PoE, the network switch that Mini is directly plugged into must support PoE, in either 802.11at or 802.11af standard.Different network switches are capable of providing differing amounts of total power to all connected devices. Mini uses approximately 7 watts in PoE mode.DC/D-TapLocated at the side of Mini is a DC connection port. This power input socket is capable of accepting power in a range of voltages from 5–18 volts DC. Mini can be powered by the included AC adaptor or alternatively via the optional D-Tap cable to power using a D-Tap compatible battery.Thermal managementMini has been engineered to be passively cooled, no fans are required. In order to achieve this the entire enclosure of Mini is designed to dissipate heat. The main processor is capable of operating up to 100º C / 212 degrees Fahrenheit.Some factors affect how much heat BirdDog will produce, and it is normal for it to feel warm to the touch.In extreme circumstances (a hot day/direct hot sun) it is advised to power Mini via DC or D-Tap as this producesless heat than PoE.BirdDog has been tested in extreme environments.BOOTING UP YOUR BIRDDOG MINIIndication of system boot processAs soon as BirdDog Mini detects a power input signal the left hand 'power/fault' light will light up green.1Typically the status will change after 10-20 seconds, at thispoint the middle 'status' light will light up blue to indicate The final stage of booting will show the status light change to white indicating the BirdDog is ready and able to be found on the computer network.3After initial boot up is complete your Mini unit will be visible as a source on any NDI compatible devices on the SAME ethernet subnet.For further networking architecture instructions including OPERATING MINIWeb configuration panelIn this release, the web configuration panel allows you to alter key settings of Mini, specifically video source settings, and video frame rates, restarting the video processing engine, changing networking parameters, and applying firmware updates.Access via web browser (URL)To access the web configuration panel please point your computer web browser to: http://birddog-xxxxx.local/“xxxxx” is the serial number of the Mini, the serial number is printed on the box and on the main unit. Note the web address is case sensitive and should be all lower case. Your computer will need to have ‘Bonjour’ services loaded in order to access the unit via it’s ‘friendly’ name described above.Apple devices come pre-installed with Bonjour, while Windows devices need a small plugin available here:https:///kb/dl999?locale=en_AUBirdDog Finder applicationIn addition to typing this URL in manually there is an applica-tion: BirdDog Finder, which is available from /firmware-updates . This application looks on the local network for any NDI capable Mini and launches the web configuration interface directly from the application.Accessing Mini via an IP addressMini is configured to automatically receive a network (IP) address from the computer network via DHCP (Dynamic Host Configuration Protocol). Most corporate, education and home networks have a DHCP server present on the network to allow this to occur. Usually your Internet Router provides this.If Mini receives an IP address automatically from this server (DHCP) the IP address can be discovered in several ways, including the BirdDog Finder application available from: /firmware-updatesAccessing Mini on a network without a DHCP serverSome standalone or private networks may not have a DHCP server. After 15 seconds of searching for an automatically assigned IP address Mini will fall back to a default address which is:192.168.100.100In order to access the web configuration panel on a network which is configured to a different subnet, change your computers IP address to match the BirdDog unit. Once you gain access to the BirdDog web configuration panel choose your IP address to match the rest of the devices on your network.For instructions on setting your computers IP address please consult your computer operating system manual or IT support resources.Note: only the last 5 digits are required for accessing the web interface.PASSWORD MANAGEMENTOnce you direct your web browser to the web configuration panel you will need to log in to change any settings.Default passwordThe web configuration panel is secured by a user-selectable password. The default password is: birddog (one word, lower case).It is recommended to change this password in a network environment where Mini is shared with other users (e.g. not private). By entering this password, the user is granted full access to the Mini configuration settings and could interrupt a live program.To change the password simply login using the default password, navigate to the network tab in the web interface, and select change password.Password resetIf you lose or forget your password, you must reset the Mini to factory settings, which will allow logging back in using the default birddog password. Please see page 12 for instructions.CONFIGURING VIDEO INPUTSAutomatic inputMini will search for any active video input on startup. It will continue to search until an active input is found.Please note that the source from your camera or video device needs to be in a supported video format.Please check firmware release notes for list of supported video formats.MINICurrent video input:Audiosetup:Mute:Tally:Input selection:DASHBOARD NETWORK CONFIG. SYSTEM LOGOUTMINIManual inputManual input configures Mini to only look at the selected video source for a specific video format and color space.This can be useful if your source is not correctly detected by Mini.BirdDog has taken as much care as possible to ensure any source is automatically detected in the correct format, however some cameras may send nonstandard timing signals or incorrect metadata. In this case please configure Mini with manual input to enable correct operation and report your camera model and video format to BirdDog so it can be added to the list of supported cameras.Current video input: Audiosetup: Mute:Tally:Input selection: Input:Configuration:DASHBOARD NETWORK CONFIG.

Particular attention should be paid to the Address and Mask fields as incorrect information entered will result in Mini not being visible on the network and a factory reset will be required in order to recover the unit.IP address recoveryIn the event that the Mini is not visible on the network, the network has changed, or the static IP address details have been lost, reset the BirdDog back to its default settings by following the factory reset procedure.BirdDog nameYou can name each Mini with a friendly name that makes sense for each production (Camera 1, Camera 2, etc). This name will appear on any N DI receiver when it looks for video coming from Mini over the network. The name must not include any special characters and can be any combina-tion of ‘a-z, 1-0, and –‘.Note: no uppercase characters are valid.On NDI receiving devices, Mini will present as a source as follows:birddog-name [AUTO]when the unit is set to automatic input.birddog-name [HDMI]when set to HDMI in manual mode.Configuration method:Address:Mask:Gateway:DHCP timeout:Static fallback address:Static fallback mask:BirdDog Name:DASHBOARD VIDEO CONFIG. SYSTEM LOGOUTMININETWORK SETTINGS AND DEVICE NAMINGDevice namingWhen Mini is first powered on it defaults to the naming convention as described in the web configuration panel section of this manual.http://birddog-xxxxx.local/It is possible to change the name along with the network settings to better suit your environment.In the web configuration panel, navigate to the network section.TALLY SUPPORTOnboard TallyMini supports Tally within the N DI protocol. Tally is a method of identifying which source is being used ‘on air’ at any particular time.Whenever a Mini source is being used on the program output of an N DI compatible receiver that supports Tally metadata, the screen will light up red on the front of the Mini unit.Program TallyMini also supports preview tally. The onboard screen will light up green when the Mini source is placed in the preview bus of the receiving switcher.In the situation where the BirdDog source is loaded on both the program and preview bus of the receiver the light will be red.Preview TallyTally border overlay on loopMini is capable of enabling Tally borders on the video loop out. This feature is particularly useful for a camera setup that has a video monitor attached.The camera operator is able to quickly see if their camera is being used in a current or preview shot in a live environ-ment. This feature is enabled via the Video settings tab in the web configuration panel.Note the Tally borders now appear on the outside edges of the external monitor and update in real time as you selectsources on your vision switcher.Current video input:Audiosetup:Mute:Tally:Input selection:AUTO/SDI/1080i/25.0/YUVDASHBOARD NETWORK VIDEO CONFIG.

To reset Mini simply press and hold the reset micro switch for 6 seconds at any time after Mini has booted up (approx. 20 seconds after power on).Once the reset process begins, BirdDog Mini will flash the LED screen between red and green repeatedly. Once the screen stops flashing, the reset process has completed and all network settings will return to default (device name and DHCP network address).The reset switch is located on the top of the unit here:FIRMWARE UPDATEMini is updateable via the web interface. Please check the below address regularly to ensure you have the latest firmware available for your device.Having the latest firmware ensures you have all the latest features and performance updates to get the most out of Mini: /firmware-updatesAfter downloading the latest firmware release, navigate to the settings tab on the Mini web configuration console click on Choose file… select the firmware update file and press the update button.SYSTEM UPDATE Update file:CONFIG. UPDATEUpdate file:DASHBOARD NETWORK VIDEO CONFIG. SYSTEM LOGOUTMINIRECEIVING NDI STREAMSThere are many applications that support receiving the NDI signal that Mini produces. Each application will vary slightly on how you choose your source.NewTek Studio MonitorN ewTek provide a free Studio Monitor application that allows you to monitor many N DI sources on a standard Windows computer. Once Studio Monitor is launched on your computer, simply right click anywhere in the interface and select your Mini from the drop-down list.Once connected to the Mini you will notice a configuration cog appears on the bottom right-hand side of the video display, this is a shortcut to access the Mini web configura-tion panel.NewTek TriCaster SeriesNewTek TriCaster series devices allow several NDI sources to be received simultaneously, the amount of simultaneous connections varies by what model TriCaster you have. Consult your TriCaster user manual to determine how many connections are available on your device.To select Mini as a source on your TriCaster, simply click on the configuration cog below your desired source location, this will bring up the Input Setting dialog, select from the drop-down list your Mini source.Once connected to the Mini you will notice a configuration cog appears next to the source drop down window, this is a shortcut to access the Mini web configuration panel. *****************。

decode在oracle的用法 -回复
decode在oracle的用法-回复解码（Decode）是Oracle数据库中的一个函数，它允许我们根据给定条件将一个列的值转换为不同的返回结果。
在本文中，我们将详细探讨在Oracle中使用Decode函数的用法和示例。
一、什么是Decode函数？Decode函数是Oracle中的条件语句。
它用于根据给定的条件对一个列的值进行转换，并返回一个结果。
它的基本语法如下：DECODE(expression, search1, result1, search2, result2, ..., default)其中，expression是要进行转换的列或表达式；search是将被比较的值；result是与之匹配的结果值；default是在没有匹配搜索值时返回的默认结果。
二、Decode函数的用法1. 简单用法Decode函数可以用于简单的条件匹配。
例如，我们有一个名为gender 的列，其值为'M'和'F'，我们希望将'M'转换为'Male'，将'F'转换为'Female'，可以使用以下语句：SELECT name, DECODE(gender, 'M', 'Male', 'F', 'Female') AS gender FROM employees;这将返回一个包含name和gender列的结果集，其中gender列的值将根据条件进行转换。
2. 使用多个条件Decode函数还可以同时使用多个条件。
例如，我们有一个名为score 的列，其值为1、2、3，我们希望将1、2、3转换为'A'、'B'、'C'，可以使用以下语句：SELECT name, DECODE(score, 1, 'A', 2, 'B', 3, 'C') AS grade FROM students;这将返回一个包含name和grade列的结果集，其中grade列的值将根据条件进行转换。

- const void *key：密钥指针，指向待加密或解密的数据。
- const void *iv：初始化向量指针，用于初始化加密或解密操作。
- int enc：指示函数是用于加密还是解密操作，0 表示解密，1 表示加密。
在mcrypt_generic_init 函数中，一个重要的参数是14 字节参数。
这个参数通常是一个预定义的常量，用于表示算法的工作模式。
对于不同的加密算法，这个参数可能会有所不同。
例如，对于AES 加密算法，这个参数可能是一个包含AES 密钥扩展的指针；对于DES 加密算法，这个参数可能是一个包含DES 密钥的指针。
mcrypt_generic_init 函数在加密和解密算法中都有广泛的应用。
在加密过程中，该函数用于初始化加密操作，将密钥和初始化向量传递给加密算法；在解密过程中，该函数用于初始化解密操作，将密钥和初始化向量传递给解密算法。
需要注意的是，在使用mcrypt_generic_init 函数时，需要确保上下文结构已经正确初始化。
通常情况下，需要在使用该函数之前调用mcrypt_init() 函数来初始化上下文结构。

14pro爱思验机报告128（最新版）目录1.解题思路概述2.C 语言编程实现3.打印沙漏效果正文【解题思路概述】在编程竞赛中，我们经常会遇到各种有趣的问题。
本次我们要解决的问题是打印一个沙漏的效果。
这个问题可以使用 C 语言来实现。
接下来，我们将详细介绍解题思路以及 C 语言编程实现的过程。
【C 语言编程实现】要实现沙漏效果，我们需要先了解沙漏的基本原理。
沙漏是由两个部分组成的：沙子和容器。
在这个问题中，我们可以将容器看作是一个字符数组，沙子则是要打印的字符。
我们需要通过循环来模拟沙漏的效果。
以下是一个简单的 C 语言程序，用于实现打印沙漏效果：```c#include <stdio.h>#include <time.h>void print_sandglass(int height, int width) {char sand[width][height];int i, j;for (i = height - 1; i >= 0; i--) {for (j = 0; j < width; j++) {sand[j][i] = "*";}}for (i = 0; i < width; i++) {for (j = 0; j < height; j++) { printf("%c", sand[i][j]); }printf("");}}int main() {int height, width;printf("请输入沙漏的高度：");scanf("%d", &height);printf("请输入沙漏的宽度：");scanf("%d", &width);print_sandglass(height, width);return 0;}```在这个程序中，我们首先定义了一个名为`print_sandglass`的函数，用于打印沙漏。
