说明：  通过计算机25针并口读写SPI总线Flash存储器(25-pin through the computer parallel port read and write SPI bus Flash memory)

基于RS485的简单现场总线通信系统设计，功能如下：单发单收，在发送状态，能够连续发送从0到99的数字； 单发单收，在接收状态，能够接收数据，并在数码管上正确地显示出来； 单发多收，在AB完成的基础上，接上多个接收设备，能够正确发送和接收； (Based on a simple RS485 field bus communication system design, the following functions: single single collection, sending state, can be continuously transmitted from 0 to 99 single single collection, in the receiving state, capable of receiving data and digital tube correctly displayed single overcharged, on the basis of completion of the AB, connected to multiple receivers, can correctly send and receive )

温度试验18b20数码4位温度计18B20.rar(8b20 temperature test 8B20.rar digital thermometer 4)

通过把开机次数记录在24C02中，并在数码管上显示出来， 124C02的写保护脚为低电平，即允许写(Boot number of records in the 24C02, and displayed on the digital 124C02 write-protect pin is low, that is allowed to write)

说明：  基于STC51单片机，实现dds的算法部分(Based on 51, the algorithm part of the realization of dds)
