16位3通道AD7707基本源码，已经调试通过，可三路轮询采集数据-16 3-channel AD7707 basic source code, debugging has been passed, can be three-way polling data collection

修改后的PDIUSBD12完整固件源码，实现51单片机的USB接口，完全通过测试。-revised PDIUSBD12 integrity of the firmware source code, achieving 51 SCM"s USB port and fully tested.

89c51 Control I2C TV Source,内有电路供大家参考。-89c51 Control I2C TV Source, there are circuits for your reference.

单片机入门的好书，详细介绍了，，，，，，，不用再介绍了-books, detailing the Medan no longer introduced

51方面的一些代码-51 some of the code

是一个用8051驱动18b20温度传感器程序，同时带有crc检验,使用c语言编写，里面有详细的说明。-8051 with a temperature sensor-driven 18b20 procedures, and with unicef.org testing, use c language, which has detailed explanations.

利用 AT89S51 单片机的 P0 端口的 P0.0 － P0.7 连接到一个共阴数码管的 a － h 的笔段上，数码管的公共端接地。在数码管上循环显示 0 － 9 数字，时间间隔 0.2 秒。 -use AT89S51 SCM P0 port of P0.0- P0.7 connected to a digital control Yam were a-h of the pen, digital tube connected to the public. The digital display tube cycle 0-9 figures, the time interval of 0.2 seconds.

功能： 1、作为主机通讯采集两路下位机数据并将此数据通过8255送出（十路水位值） 并计算水头送STC板 2、采集数据为BCD码制，先转换成二进制，处理后再转换成BCD 3、通讯采用方式3，多机通讯，上位机发地址时TB8=1，其他TB8=0 下位机SM2=1，RB8=1时产生中断后使SM2=0收发数据，结束后SM2=1 在此系统中本机硬件地址要设为0-Features: 1, as the host of two-way communication acquisition of data-bit machine and send this data through 8255 (the road level 10 value) and calculate the head sent to STC board 2, for BCD code data collection system, the first converted into binary, and then deal with the conversion into BCD 3, communication using methods 3, multi-machine communications, address PC made TB8 = 1, other TB8 = 0 under the digital machine SM2 = 1, RB8 = 1 when the failure to make SM2 = 0 to send and receive data, after the end of SM2 = 1 in this system to the local hardware address set to 0
