AT89C51 52 55单片机编程器(烧写器)制作
AT89C51/52/55单片机编程器(烧写器)制作--------------------------------------------------------------------------------AT89C51/52/55单片机编程器(烧写器)制作AT89C51是一款应用最为广泛的8051单片机，更重要的是他具有反复烧写（FLASH）的特性。
一般情况下可重复烧写1000次,这样为初学者试验提供了一个廉价的平台。
为了满足广大单片机爱好者动手的需要，本人利用半个月的时间，参考国外资料，实际设计制作成功一款简单的AT89C51/52/55单片机编程器。
由于单片机编程时序不同，这一款编程器仅仅支持ATMEL 公司的AT89C51, AT89C52, AT89C55芯片,不支持华邦或飞利浦兼容芯片。
下面是单片机编程器电路图.注:元器件清单见附录工作原理简述:Q2, Q4以及周围的几个元件构成了电平转换电路,这样节省了1片max 232芯片，在要求不高的场合，这个电路在单片机通信中可以取代MAX232。
Q1, R2,R4,DW2，4个元件为编程器提供烧写用12V电压，其中，R4, R2构成了分压电路；平时，*芯片89C51第13脚（P3.3）输出高电平，Q1导通，R2(1K)将DW2(12V)拉低，此时DW2电压由R4,R2 分压，大约3-5V 之间；当写程序时，*芯片第13脚（P3.3）输出低电平，Q1截止，DW2(12V)直接送到被烧芯片的31脚，从而提供烧写电压。
ATMEL官方网站提供的编程器器烧写电压是用LM317调整得到的，并且用到了两个高精度电阻，电路复杂且成本高，该电路经过本人数百台的实验证明非常稳定可靠.电源变压器要求为15V的电源，例如常见的3-12V直流可调电源，注意其空载电压不要低于13V , 滤波应好一些，否则可能出现编程不可靠的情况。
*芯片用IC座安装，另外找一个编程器烧写好*程序EZ51.HEX后插入，方便调试。

All FPGA devices can control the entire configuration process and retrieve data from the configuration EEPROM without requiring an external controller.The configuration EEPROM’s RESET/OE and nCS pins control the tri-state buffer on the DATA output pin and enable the address counter and the oscillator. When RESET/OE is driven Low, the configuration EEPROM resets its address counter and tri-states its DATA pin. The nCS pin also controls the output of the AT17LVxxxA configurator. If nCS is held High after the RESET/OE pulse, the counter is disabled and the DATA output pin is tri-stated. When nCS is driven subsequently Low, the counter and the DATA output pin are enabled. When RESET/OE is driven Low again, the address counter is reset and the DATA output pin is tri-stated, regardless of the state of the nCS.When the configurator has driven out all of its data and nCASC is driven Low, the device tri-states the DATA pin to avoid contention with other configurators. Upon power-up, the address counter is automatically reset.This is the default setting for the device. Since almost all FPGAs use RESET Low and OE High, this document will describe RESET/OE.4.FPGA Master Serial Mode SummaryThe I/O and logic functions of any SRAM-based FPGA are established by a configuration program. Theprogram is loaded either automatically upon power-up, or on command, depending on the state of the FPGA mode pins. In Master mode, the FPGA automatically loads the configuration program from an external memory. The AT17LVxxxA Serial Configuration EEPROM has been designed for compatibility with the Master Serial mode.This document discusses the Altera FLEX FPGA device interfaces.5.Control of ConfigurationMost connections between the FPGA device and the AT17LVxxxA Serial EEPROM are simple and self-explanatory.●The DATA output of the AT17LVxxxA configurator drives DIN of the FPGA devices.●The master FPGA DCLK output or external clock source drives the DCLK input of the AT17LVxxxA configurator.●The nCASC output of any AT17LVxxxA configurator drives the nCS input of the next configurator in a cascaded chain of EEPROMs.●SER_EN must be connected to V CC (except during ISP).AT17LV65A/128A/256A/512A/002A [DATASHEET]Atmel-2322I-FPGA-AT17LV65A-128A-256A-512A-002A-Datasheet_10201466.Cascading Serial Configuration EEPROMsFor multiple FPGAs configured as a daisy-chain, or for FPGAs requiring larger configuration memories, cascaded configurators provide additional memory.After the last bit from the first configurator is read, the next clock signal to the configurator asserts its nCASC output low and disables its DATA line driver. The second configurator recognizes the low level on its nCS input and enables its DATA output.After configuration is complete, the address counters of all cascaded configurators are reset if the RESET/OE on each configurator is driven to a Low level.If the address counters are not to be reset upon completion, then the RESET/OE input can be tied to a High level.The AT17LV65A (NRND) does not have the nCASC feature to perform cascaded configurations.7.AT17LVxxxA Reset PolarityThe AT17LVxxxA configurator allows the user to program the polarity of the RESET/OE pin as either RESET/OE or RESET/OE. This feature is supported by industry-standard programmer algorithms.8.Programming ModeThe programming mode is entered by bringing SER_EN Low. In this mode the chip can be programmed by the 2-wire serial bus. The programming is done at V CC supply only. Programming super voltages are generated inside the chip.9.Standby ModeThe AT17LVxxxA enters a low-power standby mode whenever nCS is asserted High. In this mode,the configurator consumes less than 150μA of current at 3.3V. The output remains in a high-impedance state regardless of the state of the RESET/OE input.7AT17LV65A/128A/256A/512A/002A [DATASHEET]Atmel-2322I-FPGA-AT17LV65A-128A-256A-512A-002A-Datasheet_10201410.Electrical Specifications10.1Absolute Maximum Ratings*10.2Operating ConditionsTable 10-1.Operating Conditions10.3DC CharacteristicsTable 10-2.DC Characteristics for V CC = 3.3V ± 10%Note:1.The AT17LV65A, AT17LV128A, and AT17LV256A are not recommended for new designs.Operating Temperature . . . . . . . . . . . .-40︒C to +85︒C Storage Temperature. . . . . . . . . . . . .-65︒C to +150︒C Voltage on Any Pinwith Respect to Ground . . . . . . . . .-0.1V to V CC +0.5V Supply Voltage (V CC ) . . . . . . . . . . . . . . -0.5V to +7.0V Maximum Soldering Temp.

Atmel Flash存储器AT49系列再烧录步骤
1Recommended Reprogramming Procedure forAtmel’s Flash MemoriesThe AT49X001(N)(T), AT49X002(N)(T),AT49X2048A(T), AT49X4096A(T),AT49X8192A(T) (the X designation could refer to BV, LV, or F) are sectored Flash memory devices. The memory array of each device is divided into multi-ple sectors, which can be used to store pr og r a m c o d e o r da t a. T h e A T 49X 001(N )(T ) a n d t h e AT49X002(N)(T) devices are byte-wide memories that consist of two parameter blocks, two main memory blocks, and a boot bloc k. T he AT 49X2048A(T),AT49X4096A(T), and AT49X8192A(T)are byte or word selectable through the BYTE pin. All three of these memories consist of two parameter blocks, one boot block and one main memory block. All five of these memories can be repro-grammed by first performing a chip erase and then programming the mem-ory byte by byte or word by word. This is the recommend method of reprogram-ming the whole device. A sector erase command is also available on all of these devices. The sector erase com-mand only erases a particular region in the memory. After the region is erased, it can be programmed with new data.There are, however, certain restrictions that must be obeyed when using sector er as e s. T he r e s tr ic t i o ns f or t h e A T 49X 001(N )(T ) a n d t h e AT49X002(N)(T) are slightly different th a n th e r e s tr ic t i o ns fo r t h e AT49X2048A(T), AT49X4096A(T), and the AT49X8192A(T). If the restrictions are not adhered to, incorrect data could be stored and later read from the device.For the AT49X002 (N)(T) and the AT49X001(N)(T), the two main memory sectors are designed such that sector erases of one main memory block mustalternate with sector erases of the othermain memory block. Repeated attemptsto erase and reprogram either MainMemory Block 1 or Main Memory Block2 may disturb the data in other memoryblocks. By alternating updates betweenMain Memory Blocks 1 and 2, the mem-ory contents will not be disturbed. It iscritical that whenever a main memoryblock is erased and reprogrammed theother main memory block should beerased and reprogrammed prior to anysubsequent erase of the first block. Fail-ure to perform the above mentionedprocedure could result in incorrect databeing read from the device. Each param-e te r b l o c k c an b e u p d at e dindependently; erases to the parameterblocks do not need to be alternated withany other erases. Please note that thereis no mechanism to erase just the bootblock in these devices.For the AT49X2048A, AT49X4096A,and the AT49X8192A, the parameterblocks are designed such that sectorerases of one parameter block mustalternate with sector erases of the otherparameter block. Repeated attempts toerase and reprogram Parameter Block 1or Parameter Block 2 may disturb thedata in the other parameter block. Byalternating updates between ParameterBlocks 1 and 2, the memory contents willnot be disturbed. It is critical that when-ever a parameter block is erased andreprogrammed the other parameterblock should be erased and repro-grammed prior to any subsequent eraseof the first parameter block. The mainmemory region does not need to bereprogrammed even if the parameterFlash2blocks receive multiple updates, however, whenever themain memory block is erased and reprogrammed, the twoparameter blocks should be erased and reprogrammedbefore the main memory is erased again. Similarly, theboot region does not need to be reprogrammed even if theparameter and main memory sectors receive multipleupdates, but when the boot block region is erased andreprogrammed, the main memory and the parameterblocks should be erased and reprogrammed before the boot block is erased again. Failure to perform the above mentioned procedure could result in incorrect data being read from the device.Note that the possible disturb effect only occurs during an erase operation not a programming operation (due to the shortness of the programming cycle). Please contact Atmel regarding any questions on the erasing or programming of any one of these five devices.© Atmel Corporation 2000.Atmel Corporation makes no warranty for the use of its products, other than those expressly contained in the Company’s standard war-ranty which is detailed in Atmel’s Terms and Conditions located on the Company’s web site.

单片机程式烧录步骤
1.首先将编程器插入电脑的USB接口内，这时编程器上电源指示灯红灯和绿灯亮。
表示可
以进行芯片读写了。
2.双击该图标打开烧录软件，显示出主程序窗口。
3.点击工具栏该图标，执行后弹出对话框窗口
用鼠标点击MPU---ATMEL---AT89C51,可以逐级展开树形列表，最后找到要选择的单片机的型号，并点击OK确定，退出选择窗口，回到主程序窗口。
4.在主程序窗口，点击“Placement”页面，可以看到AT89C51在锁紧插座上的位置图，
如下图所示:
扳手位置
将芯片放入插槽内，并将扳手压下，将芯片压紧。
5.选择工具图标，用于在缓冲区中显示打开的已存文件，执行后弹出文件窗口：
选择自己需要的文件名后NYB0201K，点击开启旧档选项，出现对话框，确认文件格式。
点击OK，该文件即按要求装入缓冲区。
显示如下：
6.点击图标，开始写缓冲区数据到芯片内，写毕会在报告栏显示。
若烧录正常将显示如下画面。
如果写出错，会在报告栏显示出错内容。
烧录成功后，将扳手扳起，取出芯片即可。
如果连续烧录多片，将重新插入新的芯片，扳下扳手锁紧座，直接点击图标即可。
其他步骤不需要重新设置。
KILL软件的使用方法
1、双击桌面上的图标，打开以下窗口：点“工程”，新建工程：给工程起一个名字，我用“xiaodeng”就是小灯的意思，然后点保存：选择你使用的芯片型号，我用的是Atmel公司生产的89s51，双击Atmel：在下面找到At89S51后，点击它，然后确定：点击确定后，接下来再为你的工程新建一个文件弹出以下窗口：在弹出的窗口里面写入你的汇编程序：然后点文件，另存为：为你的文件起一个名字，我这里名字为“xiaodeng.asm”。
注意文件的扩展名不能省略，而且必须是“.asm”：点击保存，出现以下界面：将左边Target 1前面的“+”号展开，在它下面的字符“Source Group 1”上点击鼠标右键，再点击增加文件到组：在文件类型中点击asm源文件：在文件中找到你刚才新建的xiaodeng.asm文件，然后点击Add加入：只需要加入一次就够了，如果再次加入，将出现以下画面，不要紧，点确定就好了：这时候，左边的文件夹“Source Group 1”前面就有了一个“+”号：点击该“+”号展开后，下面就出现了一个名为“Xiakdeng.asm”的文件，说明已经将文件加进来了。
接下来将鼠标移到“Target 1”上，点击右键，再点击“目标‘Target 1’属性”：弹出以下窗口：点“输出”，在新弹出的窗口中，一定要确保“E生成 HEX文件”前面的小方格内有一个勾“√”，即选中该项，然后再点击“确定”：最后点击下面的符号：即“构造所有目标文件夹”，当出现以下画面时，说明目标文件“xiaodeng.hex”文件已经生成了：这个“xiaodeng.hex”文件就是往单片机89s51里面写的文件。
有了这个文件，就可以用编程器将该文件烧写到89S51单片机中了，一个廉价的通用编程器要300元左右，我自己制作的仅花费了几十元，如果没有编程器，也可以找修理电脑主板的那些师傅代为烧写，他们应该都有的，因为这是烧写“BIOS”的常用工具。

atmega328p 程序烧写
atmega328p 程序烧写有关ATmega328P芯片程序烧录的详细步骤和解释。
ATmega328P是一款用于嵌入式系统的低功耗高性能微控制器，被广泛应用于各种电子设备和项目中。
在将程序烧写到ATmega328P芯片之前，我们需要准备一些工具和软件，并按照一定的步骤进行操作。
本文将详细介绍烧录程序的整个过程。
1. 准备烧录工具在烧录程序之前，首先需要准备一些必要的烧录工具，包括：- ATmega328P芯片：确保芯片是全新的或已经擦除过。
- 程序烧录器：常见的烧录器有AVRISP mkII和USBasp等。
选择一种适合自己的烧录器。
- 编程软件：我们可以使用Atmel Studio或Arduino IDE进行编程和烧录操作。
2. 设置芯片和烧录器连接将ATmega328P芯片插入烧录器的插槽中，并连接烧录器与电脑，确保两者之间的连接是可靠的。
3. 打开编程软件打开所选择的编程软件，如Atmel Studio或Arduino IDE。
这两种软件都支持ATmega328P芯片的编程和烧录。
4. 设置编程软件在软件界面中，找到芯片型号设置选项。
在Atmel Studio中，我们可以通过"工具->设备工具->设备设置"找到并选择"ATmega328P"芯片。
在Arduino IDE中，点击"工具->微控制器"并选择"Arduino UNO"。
确保选择了正确的芯片型号和与之相对应的烧录器。
5. 导入程序文件或编写代码现在，我们可以通过两种方式来向芯片烧写程序。
一种方式是导入已经编写好的程序文件，另一种方式是直接在软件中编写代码。
如果我们已经有了一个已经编写完成的程序文件，我们可以在软件中打开该文件。
在Atmel Studio中，我们可以通过"文件->打开->文件"来打开程序文件。
