TCLMS801机芯电路原理与故障检修实例资料

TCLMS801机芯电路原理与故障检修实例资料TCL MS801机芯液晶彩电主要电路原理、调试与检修实例杨德印TCL MS801机芯的系列机型属于Android 智能数字电视，基本功能包括模拟ATV、数字DTV、互联⽹、全信源3D 和Android 4.0 UI。

主要的型号有L46V7500A-3D、L55V7500A-3D、L65V7500A-3D等。

各个电路板的连接如图1所⽰。

图1⼀、电源电路该机的电源电路由主电源电路（24V电源）、待机电源电路（3V3SB电源）、12V电源、5V电源、3.3V 电源、2.5V电源等构成，如图2所⽰。

图21．24V、3V3SB电源电路24V、3V3SB电源设置在电源板上，其中3V3SB电源是不受控电源，通电后就会进⼊⼯作状态，为微控制系统提供3.3V⼯作电源。

24V电源是受控电源，开机时来⾃微控制器电路的待机/开机信号POWER_ON 为⾼电平时，24V电源才能⼯作并输出24V电压；待机时POWER_ON为低电平，24V电源⽆电压输出。

2．12V、5V电源电路12V、5V电压由24V电压经DC-DC型功率变换器转换⽽来，如图3所⽰。

12V、5V电源电路的构成和⼯作原理相同，仅元器件符号不同，下⾯以12V电源电路为例进⾏介绍。

图3（1）电压变换24V电压经L008、L009和C029滤波后，⼀路为5V电源供电；另⼀路不仅加到模块Q003的⑤、⑥脚，为内部的下端开关管（场效应管）漏极供电，⽽且加到电源控制芯⽚U004（RT8110B）的7脚，为它供电。

U004内的控制电路得电⼯作，产⽣⼀组对称但极性相反的激励脉冲信号从②④脚输出。

当②脚输出的激励信号为低电平、④脚输出的激励信号为⾼电平时，使Q003内的上端开关管截⽌，⽽使下端的开关管导通，该开关管导通后，24V电压经它的D/S极和电感L004对C068、C069、C074充电，不仅在它们两端建⽴电压，⽽且在L004两端产⽣左正、右负的电动势；当4脚输出的激励信号为低电平②脚输出的激励信号为⾼电平时，使Q003内的下端开关管截⽌，⽽使上端的开关管导通，该开关管导通后，L004 通过⾃感产⽣右正、左负的电动势，该电动势通过C068、C069、C074到地，再通过Q003内的上开关管到L004左端构成放电回路，继续为C068、C069、C074补充能量，从⽽提⾼了该电源的⼯作效率。

SP809 SP810微处理器监控电源管理芯片说明书

S P 809 / S P 8103 P i n M i c r o p r o c e s s o r S u p e r v i s o r C i r c u i tGENERAL DESCRIPTIONThe SP809/SP810 are low power microprocessor (μP) supervisory circuits used to monitor power supp lies in μP and digital systems.They provide applications with benefits of circuit reliability and low cost by eliminating external components. If the VCC supply voltage falls below preset threshold then a reset signal is asserted for at least 140ms after V CC has risen above the reset threshold. Both the SP809 and SP810 were designed with a reset comparator to help identify invalid signals, which last less than 140ms. The onlydifference between them is that they have an active-low RESET output and active-high RESET output, respectively. Low supply current (1μA) makes SP809/SP810 ideal for portable equipment.The devices are available in 3 pin SOT-23 package.Part NumberOutput Type SP809N Open Drain Active LowSP809 Push-Pull Low SP810Push-Pull Active HighAPPLICATIONS• Portable Electronic Devices • Electrical Power Meters • Digital Still Cameras • µP Power MonitoringFEATURES• Ultra Low Supply Current 1µA (typ) • Guaranteed Reset valid to V CC = 0.9V • 140ms Power-On Reset Pulse Width • Internally Fixed Threshold2.3V, 2.6V, 2.9V,3.1V,4.4V, 4.6V • 1.5% Voltage Threshold Tolerance • 3 Pin SOT-23 PackageTYPICAL APPLICATION DIAGRAMFig. 1: SP809 / SP810 Application DiagramABSOLUTE MAXIMUM RATINGSThese are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied.

These μP supervisory circuits assert reset to prevent code execution errors during power-up,power-down, or brownout conditions. Reset is guaranteed to be a logic low for V TH>V CC>0.9V. Once V CC exceeded the reset threshold, an internal timer keeps RESET low for the reset timeout period; after this interval, RESET goes high.If a brownout condition occurs (V CC drops below the reset threshold), RESET goes low. Any time V CC goes below the reset threshold, the internal timer resets to zero, and RESET goes low. The internal timer is activated after V CC returns above the reset threshold, and RESET remains low for the reset timeout period.B ENEFIT OF H IGHLY A CCURATE R ESETT HRESHOLDSP809/810 with specified voltage as 5V±10% or 3V±10% are ideal for systems using a 5V±5% or 3V±5% power supply. The reset is guaranteed to assert after the power supply falls below the minimum specified operating voltage range of the system ICs. The pre-trimmed thresholds are reducing the range over which an undesirable reset may occur.Fig. 10: Timing WaveformsAPPLICATION INFORMATIONN EGATIVE G OING V CC T RANSIENTSIn addition to issuing a reset to the µP during power-up, power-down, and brownout conditions, SP809 series are relatively resistant to short-duration negative-going V CC transient.E NSURING A V ALID R ESET O UTPUT D OWNTO V CC=0When V CC falls below 0.9V, SP809 RESET output no longer sinks current; it becomes an open circuit. In this case, high-impedance CMOS logic inputs connecting to RESET can drift to undetermined voltages. Therefore, SP809/810 with CMOS is perfect for most applications of V CC down to 0.9V.However in applications where RESET must be valid down to 0V, adding a pull-down resistor to RESET causes any leakage currents to flow to ground, holding RESET low. I NTERFACING TO µP WITH B IDIRECTIONALR ESET P INSThe RESET output on the SP809N is open drain, this device interfaces easily with μPs that have bidirectional reset pins. Connecting the μP supervisor's RESET output directly to the microcontroller's RESET pin with a single pull-up resistor allows either device to assert reset.

DM542全数字步进驱动器用户手册说明书

Website: Email:*******************User’s ManualForDM542Fully Digital Stepper Drive Attention: Please read this manual carefully before using the drive!DM542Digital two-phase stepper driver 一、Introduction1. OverviewDM542 is the new digital stepping motor driver of our company. It adopts the latest 32-bit DSP digital processing technology. The driver control algorithm uses advanced variable current technology and advanced frequency conversion technology.The driver has low heat generation, small motor vibration and stable operation. Users can set any subdivision within 200~51200 and any current value within the rated current, which can meet the application needs of most occasions. With built-in micro-segmentation technology, even in the case of low subdivision, high subdivision can be achieved, and the operation at low, medium and high speeds is smooth and the noise is extremely small.The parameter internal power-on auto-tuning function is integrated in the drive, which can automatically generate optimal operating parameters for different motors to maximize the performance of the motor.2. Features3. Application fieldSuitable for all kinds of small and medium-sized automation equipment and instruments, such as: engraving machine, marking machine, cutting machine, laser phototypesetting, plotter, CNC machine tool, automatic assembly equipment, etc. It is especially effective in applications where users expect small noise and high speed.二、Electrical, mechanical and environmental indicators1.

The computer can write data intodigital output registers, treating them as I/O ports. The output fromthese registers can then be wired to an interface device, such as arelay. Thus, by sending data to an output register, it is possible toactivate and deactivate a relay. The relay could, in turn, control, forexample, an electric motor.Similarly, a digital input register can be considered as an I/O port that has wires attached to individual bit locations. When read, the datareflects the states of signals on the wires. Digital input registers canbe used to monitor incoming signals. For example, to determinewhether a switch is open or closed, the switch can be wired to theinput of a digital input register.The PCI-1760 Relay Actuator & Isolated Digital Input Card is a PCadd-on card for the PCI bus, which was designed with this idea inmind. This card offers the user 8 opto-isolated digital inputs withisolation protection of 2500 V DC for collecting digital signals undernoisy environment, 8 relay actuators for serving as ON/OFF controldevices or small power switches, and 2 isolated PWM (Pulse WidthModulation) outputs for user's specific applications.Each isolated digital input supports both dry contact and wet contact, designated by jumper settings, so that it can easily interface withother devices. Additionally, for easy monitoring, each relay isequipped with one red LED to reflect its ON/OFF status.Digital filter eliminates unexpected inputnoiseThe PCI-1760 includes a programmable digital filter on each digitalinput channel to eliminate the unexpected signal or noise from thecard's inputs. When the digital filter is enabled, the state of thecorresponding input channel will not update immediately until onehigh/low signal has lasted for a period which is programmed by theuser.2PCI-1760 User's ManualInterrupt function ensures faster systemresponseThe PCI-1760 provides a ìPattern Matchî interrupt function for thedigital input channels. The card monitors the state of some or all ofthe input channels and compares it with a pre-set pattern. When thereceived state matches the pre-set pattern, the card generates aninterrupt signal to the system.The ìChange of Input Stateî interrupt function also monitors the state of the input channels. When any input changes its state, the cardinterrupts the system to handle this event.Up event counter for each DIEach isolated digital input channel is connected to a 16-bit UP eventcounter. A counter will increment by 1 whenever it reads either arising-edge (low to high) or a falling-edge (high to low) input signalwith the maximum frequency of 500 Hz. When the counter overflowsor reaches a pre-set value (programmed by software), it generates aninterrupt signal to the PC.1.2Features•8 opto-isolated digital input channels•8 relay actuator output channels• 2 opto-isolated PWM outputs•LED indicators to show activated relays•Jumper selectable dry contact/wet contact input signals•16-bit Up counter function for each DI•Programmable digital filter function for each DI•Pattern match interrupt function for each DI•Change of input state interrupt function for each DIChapter 1 General Information 31.3Applications•Digital signal and contact status monitoring•Industrial On/Off control•Signal switching•External relay driving1.4SpecificationsIsolated Digital Input•Channels: 8•Opto-isolator: PC354•Input voltage: 5 ~ 12 VHigh: > 4.5 VLow: < 1.0 VUncertain: 1.0V ≤ Vin ≤ 4.5V•Input resistance: 1k Ω @ 1/4 W•Isolation voltage: 2500 V DC•Digital Filter:Minimum effective High input period ≥ [(2 ~ 65535) x 5 ms] + 5 msMinimum effective Low input period ≥ [(2 ~ 65535) x 5 ms] + 5 ms•16-bit UP counter:Maximum effective input frequency: 500HzMinimum High period ≥ 1 msMinimum Low period ≥ 1 ms4PCI-1760 User's ManualRelay Output•Channels: 8•Relay type: single-pole double-throw (SPDT, Form C),but RE2 ~ RE7 are hooked up as single-pole single-throw (SPST)•Output type:RE0 and RE1: NC and NO outputsRE2 ~ RE7: NC or NO outputs (selected by jumper)•Rating contact load: 120 V AC @ 0.5 A or 30 V DC @ 1 A•Contact resistance: less than 100 mΩ initially•Dielectric strength:Coil to contacts (deenergized): 1500 Vrms (1 minute)Between open contacts (deenergized & energized):1000 Vrms (1 minute)•Life expectancy:200,000 operations @ 0.5 A 120 V AC500,000 operations @ 1.0 A 30 V DC•Operating & Releasing time:Operating time: 5 ms max.Releasing time: 5 ms max.Isolated PWM output•Channels: 2•Isolation voltage: 2500 V DC•Scaling resolution: 16 bits (100 µs for each step)High period = [(1 ~ 65535) x 100 µs ] ± 50 µs (max.)Low period = [(1 ~ 65535) x 100 µs ] ± 50 µs (max.)•Output level:High: (5 ± 0.5) VLow: < 0.8 VChapter 1 General Information 5General•Power consumption: +5V @ 450 mA (typical), 850 mA (max.)•Operating temperature: 0 ~ +60° C (32 ~ 140° F)(refer to IEC 68 - 2 - 1, 2)•Storage temperature: -20 ~ +70° C (-4 ~ 158° F)•Operating humidity: 5 ~ 95%RH non-condensing(refer to IEC 68-2-3)•MTBF: over 117,317 hrs @ 25°C, grounded, fixed environmentPhysical•Connector: One 37-pin D-type connector•Dimensions: 175 x 100 mm (6.9" x 3.9")6PCI-1760 User's ManualIG N DID I7-ID I7+ID I6-ID I5-ID I4-ID I3-ID I2-ID I1-ID I0-ID I6+ ID I5+ ID I4+ ID I3+ ID I2+ ID I1+ ID I0+P W M0P W M1R7_O U T R6_O U T R5_O U T R4_O U T R3_O U T R2_O U TR7_C O M R6_C O M R5_C O M R4_C O M R3_C O M R2_C O M R1_N O R1_N C R1_C O MR0_C O M R0_N C R0_N O1.5Pin AssignmentsDescription of pin use:IGND: Isolated Ground for PWMoutputs and dry contact wiring ofIDIIDIn+(n = 0 ~ 7):Isolated digital input+IDIn- (n = 0 ~ 7):Isolated digital input-PWMn (n = 0, 1):Isolated PWM outputRn_OUT (n = 2 ~ 7):Normally Open/Closed pin ofRelay outputRn_NO (n = 0 ~ 1):Normally Open pin of RelayoutputRn_NC (n = 0 ~ 1):Normally Closed pin of RelayoutputRn_COM (n = 0 ~ 7):Common pin of Relay outputChapter 1 General Information 71.6Block DiagramFigure 1.1PCI-1760 Block Diagram 8PCI-1760 User's Manual2.1 Initial InspectionBefore installing the PCI-1760, check the card for visible damage.We have carefully inspected the card both mechanically andelectrically before shipment. It should be free of marks and inperfect order upon receipt.As you unpack the PCI-1760, check it for signs of shipping damage(damaged box, scratches, dents, etc.). If it is damaged or fails to meetspecifications, notify our service department or your local salesrepresentative immediately. Also, call the carrier immediately andretain the shipping carton and packing materials for inspection by the carrier. We will then make arrangements to repair or replace the unit.2.2 UnpackingThe PCI-1760 contains components that are sensitive and vulnerableto static electricity. Discharge any static electricity on your body toground by touching the back of the system unit (grounded metal)before you touch the board.Remove the PCI-1760 card from its protective packaging by grasping the card's rear panel. Handle the card only by its edges to avoid static discharge which could damage its integrated circuits. Keep theantistatic package. Whenever you remove the card from the PC,protect the card by storing it in this package.Y ou should also avoid contact with materials that hold static electrici-ty such as plastic, vinyl and styrofoam.Check the product contents inside the packing. There should be onecard, one CD-ROM, and this manual. Make sure nothing is missing. 10PCI-1760 User's Manual2.3Jumper SettingsWe designed the PCI-1760 with ease-of-use in mind. It is a "plug andplay" card, i.e. the system BIOS assigns the system resources such asbase address and interrupt automatically. There are only threefunctions with 15 jumpers to be set by the user (see Figure 2.1 andTable 2-1). Y ou may refer to the figure below for help in identifyingcard components.Figure 2.1 Location of jumpers and relaysChapter 2 Installation 11Table 2.1: Summary of jumper settingsSetting dry/wet contact connection foreach DIEach of the 8 isolated digital input channels accepts either drycontact or 5 ~ 12 V DC wet contact inputs according to the correspond-ing jumper settings (see Table 2.2). The default setting for each IDI is dry contact. For detailed information, please refer to Chapter 3.Setting relay outputs to be NC/NO6 relay outputs, RE2 ~ RE7, are single-pole single-throw (SPST),which can be jumper set as either nornally open (NO) or normallyclose (NC) (see Table 2.3). The default settings for RE2 ~ RE7 arenormally open. For detailed information, please refer to Chapter 4.Note!: RE0 and RE1 are Form C relays12PCI-1760 User's ManualChapter 2 Installation 13Table 2.2: IDI and corresponding jumperTable 2.3: Relay output and corresponding jumperSetting the time to reset the relay outputsSome users will want the capability of clearing each relay output when the system (or PC) issues a reset signal on the PCI bus. Some users will want to clear their relays only as part of system power-on.The PCI-1760 satisfies both these needs by providing jumper JP14.Depending on the application, this capability may allow relay outputs to be "OFF" without requiring a complete shutdown of processes controlled by the card.Complete loss of power to the chip clears the chip memory. Thus, no matter how JP14 is set, if the power to the PCI-1760 is disconnected,the relay initial power-on state will be "OFF" (NC or NO, depending on the user's settings).2.4Installation InstructionsThe PCI-1760 can be installed in any PCI slot in a computer. Howev-er, to avoid any mistakes or dangerous conditions, please refer to your computer user's manual before you follow the installation procedurebelow:1. Turn off your computer and any accessories connected to thecomputer.Warning!TURN OFF your computer power supply wheneveryou install or remove any card, or connect anddisconnect cables.2. Disconnect the power cord and any other cables from the back ofthe computer.3. Remove the cover of the computer.4. Select an empty 5 V PCI slot. Remove the screw that secures theexpansion slot cover to the system unit. Save the screw to securethe interface card retaining bracket.5. Carefully grasp the upper edge of the PCI-1760. Align the hole inthe retaining bracket with the hole on the expansion slot and alignthe gold striped edge connector with the expansion slot socket.Press the card into the socket gently but firmly.

In addition to supporting both dry and wetcontacts, this card provides "Digital Filter", "Pattern Match", "Change of State" and 16-bit UP counter functions for each digital input channel. All these functions are optional. Users can enable/disable each function to fit their applications. Figure 3.1 is a simplified function logic block diagram for the PCI-1760's digital inputs. The following sections will introduce these useful functions.Figure 3.1: PCI-1760 function logic block diagram3.2 Dry Contact Support for Each IDIEach of the 8 isolated digital input channels accepts either dry contact or 5 ~ 12 V DC wet contact inputs as determined by the corresponding jumper settings (see Table 2.1 and Table 2.2). Dry contact capability allows an input channel to respond to changes in an external circuit (e.g., the closing of a switch in the external circuit)when no voltage is present in the external circuit. Figure 3.2 shows the internal and external circuitry, with both wet and dry contact components connected as an input source for one of the PCI-1760's isolated digital input channels.Note!:The default settings of jumpers JP0 ~ JP7 are drycontact, just as shown in Figure 3.2.Figure 3.2: Dry and wet contacts3.3 Digital FilterEach digital input channel has a programmable digital filter foreliminating unexpected signals and noise from the card circuitry. The user can set different digital filtering parameters for each inputchannel in different applications. The following is a functionaldescription of the digital filter.1.When a digital filter is enabled, the PCI-1760 will sample thesignals at the enabled input channel at a 5 ms sampling rate.2.When a high or low signal is present at a digital input channelwhose digital filter function is enabled, the signal will be filteredout as noise unless it lasts for an effective period.3.The effective period is determined by multiplying the samplingrate (5 ms) by the sampling number (2 ~ 65535) chosen by the user,i.e.Effective period = Sampling number x 5 ms.Chapter 3 Digital Input Programming 17Note!: The sampling numbers for High and Low signals can be different. For example, assuming that the samplingnumbers are 10 for a High signal and 15 for a Low signal,the state of the digital input channel will update if a highsignal lasts for 50 ms or more, or a low signal lasts for75 ms or more.Note!: For digital input channels whose digital filter functions are not enabled, the PCI-1760 samples the signals at theseinput channels at a 100 µs sampling rate and immediate-ly updates the state of these input channels when thesignal changes.3.4 Pattern MatchThe PCI-1760 provides a pattern match interrupt function on itsdigital input channels. It monitors the status of the enabled inputchannels, and compares these with a pre-set pattern. When the actualstate matches the pre-set pattern, the PCI-1760 delivers an interruptsignal to the system. This function releases the CPUfrom the burdenof polling all the I/O points, enabling a PC to handle more I/O pointswith higher performance. An example follows:Example 3.1 Assume that the pattern match function is enabled forthe isolated digital input channels IDI1, IDI2, IDI6 and IDI7 (i.e. IDI0, IDI3, IDI4, and IDI5 are ignored during the pattern match process).Then the user can set the pattern match values for the enabled inputchannels. The table below shows one possibility.In thes example, when IDI1, IDI2 and IDI7 are high and IDI6 is low, an interrupt signal will be generated. No matter what the status of IDI0,IDI3, IDI4 and IDI5 are, these will not affect the result.18PCI-1760 User's Manual3.5 Change of Input StateThe PCI-1760 also provides a change of state interrupt function oneach digital input channel allowing users to monitor the status of theenabled digital input channels more efficiently. When one of theenabled channels changes its state, the PCI-1760 delivers an interrupt signal to the system to handle this event. The function can be set togenerate an interrupt for a rising edge signal, a falling edge signal, ora signal with both edges, depending on user application require-ments. The following is an example.Example 3.2 Assume that the change of input state function for theisolated digital input channels IDI1, IDI2, IDI6 and IDI7 is enabled(i.e. the signals at IDI0, IDI3, IDI4 and IDI5 are ignored by the changeof state function). When a change of state occurs in IDI1, IDI2, IDI6or IDI7, an interrupt signal is sent to the system.3.6 CounterEach digital input channel is connected to a 16-bit UP event counterwith a maximum frequency of 500 Hz. Each counter is enabled ordisabled by software. The following describes its major functions:1. Counter reset valueEach counter has its own reset value. When most cards are poweredon, the start-up value of a counter is zero, but in the PCI-1760, usersare allowed to set the reset value to a number between 0 and 65535.This is a very useful feature when one of the counters needs to bestarted from a non-zero number.2. Counter value match interruptAll eight counters also have a counter value match interrupt function.When this interrupt function is enabled, an interrupt signal will begenerated if the counter value reaches a pre-set counter match value.The counter will continue to count until an overflow occurs, then itwill go back to its reset value zero and continue the counting process.Chapter 3 Digital Input Programming 1920PCI-1760 User's ManualQ3. OverflowAn overflow will occur when the counter reaches its maximum value,65535, and an interrupt signal will be generated when this function is enabled.4. Count edgeA user can set each individual channel's counter to count either falling edge (high-to-low) or rising edge (low-to-high) signals. The appropriate setting depends on the initial state of the input signals; if they are low, a rising edge setting would be appropriate.The following figure illustrates counter operation. Counting starts from the counter reset value and continues until it reaches its match value. At that time, an interrupt will also be generated. Afterwards,the counter continues to count until it reaches the maximum capacity of 65535, at which time an overflow interrupt is generated and the counter is reset to its reset value, and continues to count.Figure 3.3: Example for counter operation22PCI-1760 User's ManualThe PCI-1760 provides 8 relay outputs to serve as On/Off control devices. The user can enable and disable each relay output using software commands. For easy monitoring, each relay output isequipped with one red LED to show its On/Off status.Note!: Please refer to Appendix B for more information aboutrelay output software programming.Of these eight relays, two relays (RE0 and RE1) are single-poledouble-throw (SPDT, Form C) and six (RE2 ~ RE7) are single-pole single-throw (SPST), which can be set as either normally open (NO) or normally closed (NC) via jumper settings. The following figureillustrates the structures and connections of the relay outputs.Note!: The default setting for RE2 ~ RE7 is narmally open (NO).Please refer to Chapter 2 for detailed information con-cerning the setting of jumpers.C O MN C /N OREn (n =2 ~ 7)REn (n = 0, 1)JPn+6Figure 4.1: Relay structures and connections24PCI-1760 User's Manual5.1 OverviewThe PCI-1760 also provides two PWM (Pulse-Width Modulation)outputs with 2500 V DC isolation. Each PWM output can be indepen-dently enabled or disabled using software commands.5.2 Introduction to PWMA pulse-width modulated waveform is created when the High and Low periods of a periodic rectangular signal are varied. In the PCI-1760, the user can individually set each channel’s High and Low periods for from 1 to 65535 units (1 unit = 100µs), depending on his needs.The user can also define the “burst count”, the number of cycles generated in each PWM channel. It can be a specific number of cycles or a non-stop cycle. If not a non-stop cycle, the predefined number of cycles must be between 1 and 65535.When the user enables a PWM output, the PCI-1760 will check the PWM burst count value first, If the burst count value is zero, the PWM output will be non-stop. If the burst count value is non-zero, the PWM will output the number of cycles which equals the burst count value,then stop. If the user wants to output another pulse chain, he has to set a new burst count value, then enable the PWM again.Note!: Please refer to Appendix B for more information aboutPWM software programming.L o w p e rio d1 ~ 65535 u n its H ig h p e rio d 1 ~ 65535 u n itsA.1 OverviewThe PCI-1760 is delivered with an easy-to-use 32-bit DLL driver foruser programming under the Windows 95/98/NT operating system. To program the PCI-1760, users are advised to use the 32-bit DLL driverprovided by Advantech to avoid the complexity of low-level pro-gramming by register.When it is necessary to program the PCI-1760 at a register level, themost important consideration is to understand the function of thecard’s registers. The PCI-1760 occupies 128 bytes in the PC’s I/Ospace. In general operations, it only requires 8 I/O spaces, 4 forwriting commands and 4 for reading commands. To enable/disablethe interrupt function, the PCI-1760 requires another 4 I/O spaces toread/write. The address of each register is specified as an offset fromthe card’s base address.A.2OMB0 ~ 3: Outgoing Mailbox BytesWrite OMB3OMB2OMB1OMB0 Address (Hex.)Base + 0x0F Base + 0x0E Base + 0x0D Base + 0x0COMB3:This byte is not currently used.

Users can detect when acommand has been executed by reading its echo in IMB2. When agiven command is executed twice in a very short period, it can bevery difficult to identify the two separate commands just by readingthe command code in IMB2. A simple solution to this problem is towrite a command code “00” between the two identical commands inOMB2. The command code “00” clears the first command code inIMB2 and lets the user clearly recognize execution of the secondcommand. Of course, if a user does not need to distinguish eachseparately executed command, the insertion of the command code“00” between the two identical commands is not necessary.32PCI-1760 User's Manual。

(10)六、心得体会.................................................. .. (12)8位数码管动态显示电路设计一、设计任务与要求1. 设计个8位数码管动态显示电路，动态显示1、2、3、4、5、6、7、8。

2. 要求在某一时刻，仅有一个LED数码管发光。

3. 该数码管发光一段时间后，下一个LED发光，这样8只数码管循环发光。

4. 当循环扫描速度足够快时，由于视觉暂留的原因，就会感觉8只数码管是在持续发光。

5、研究循环地址码发生器的时钟频率和显示闪烁的关系。

二、总体框图设计的总体框图如图2-1所示。

图2-1总体框图三、选择器件 1、数码管数码管是一种由发光二极管组成的断码型显示器件，如图1所示。

U13DCD_HEX图1 数码管数码管里有八个小LED 发光二极管，通过控制不同的LED 的亮灭来显示出不同的字形。

数码管又分为共阴极和共阳极两种类型，其实共阴极就是将八个LED 的阴极连在一起，让其接地，这样给任何一个LED 的另一端高电平，它便能点亮。
