51单片机烧写方法一、引言51单片机是一种常用的单片机，广泛应用于各种电子设备中。
烧写是将程序代码写入51单片机的过程，是使用单片机的基础操作。
本文将介绍51单片机的烧写方法，帮助读者了解如何正确地进行烧写操作。
二、烧写工具准备进行51单片机的烧写操作，首先需要准备以下工具：1. 51单片机烧写器：一种专门用于将程序代码写入51单片机的设备，常见的有USB转串口烧写器和ISP烧写器两种；2. 电脑：用于连接烧写器，并通过烧写软件进行烧写操作；3. 烧写软件：根据烧写器的型号选择相应的烧写软件，常见的有STC-ISP、Flash Magic等。
三、烧写步骤1. 连接烧写器：将烧写器通过USB或串口连接到电脑上，并确保连接正常；2. 打开烧写软件：根据烧写器的型号选择相应的烧写软件，并打开软件；3. 设置烧写参数：在烧写软件中选择正确的单片机型号，并设置好烧写参数，如烧写速度、烧写模式等；4. 导入程序代码：将需要烧写的程序代码导入烧写软件中，通常是通过选择文件或拖拽文件的方式导入；5. 连接单片机：将51单片机通过编程接口连接到烧写器上，确保连接正常；6. 擦除单片机：在烧写软件中选择擦除操作，将单片机中原有的程序代码擦除，以便写入新的程序代码；7. 烧写程序代码：点击烧写软件中的烧写按钮，开始将程序代码写入单片机中；8. 等待烧写完成：等待烧写软件提示烧写完成，此时烧写操作已经完成；9. 断开连接：断开51单片机与烧写器之间的连接，完成烧写过程。
四、烧写注意事项1. 确认单片机型号：在烧写操作之前，要确认所使用的单片机型号，选择正确的烧写软件和参数设置；2. 确保连接正常：在进行烧写操作之前，要检查烧写器与电脑、单片机之间的连接是否正常，避免烧写失败；3. 备份程序代码：在擦除单片机之前，建议先备份原有的程序代码，以便需要时恢复；4. 不要中断烧写过程：在烧写过程中，不要随意中断电源或断开连接，以免造成单片机损坏；5. 验证烧写结果：在烧写完成后，可以通过读取单片机中的程序代码，与原始代码进行比对，以验证烧写结果的准确性。
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.
