包括单片机c8051f202x系列的datasheet，大家看一下

一个简单的时钟开发程序,显示时,分,秒!!! 可以接上数码管再加上简单的转换就可以制作为简单的电子表-Clock to develop a simple procedure, show hours, minutes and seconds!!! Can be connected to digital tube coupled with a simple conversion can create a simple e-form

使用FREESCALE单片机内部的EEPROM的程序，经本人试过，完全没有问题，不过使用之前，要先修改内存映射。-Using Freescale

DAC7611，12位串口DA驱动程序，只需将代码中的四个端口按自己的电路修改就可以使用。-DAC7611, 12 bit serial DA driver, just the code of the four ports in accordance with their own modifications on the circuit can be used.

P89V51RD2系列芯片是具有串口下载功能（ISP）和在KEIL中进行调试的功能（SOFTICE）。 新的芯片是ISP功能，通过FlashMagic 软件可以设置其为SOFTICE功能。 但要想回到ISP功能，则没有现成的好办法，只有通过编程器了。 但现在可以通过这个程序来恢复其ISP功能（禁止SOFTICE）。-P89V51RD2 series with the serial port chip is the ability to download (ISP) and the KEIL for debugging feature (SOFTICE). The new chip is the ISP, through FlashMagic software can be set to SOFTICE its function. However, to return to the ISP, there is no ready-made good, and that only through a programmer. But now through this procedure to restore its ISP (Prohibition SOFTICE).

AVR单片机的EEPROM的读写程序, 通过TWI接口读写.-AVR MCU EEPROM reading and writing process, reading and writing through the TWI interface.

必用的C程序,单片机实现滤波器的方法-Procedures must be used in C, single-chip filter methods realize

本实验实现PS/2接口与RS-232接口的数据传输， PS/2键盘上按下按键，可以通过RS-232自动传送到主机的串口调试终端上（sscom32.exe）； 并在数据接收区显示接收到的字符。 串口调试终端的设置：波特率115200，一个停止位，无校验位。 -Realize this experiment, PS/2 interface with RS-232 data interface, PS/2 keyboard to press the button, through RS-232 automatic transmission to the host serial debug terminal (sscom32.exe) and data receiving display received characters. Serial debug terminal settings: 115200 baud rate, one stop bit, no parity bit.
