这是一个单片机的简易汽车计费系统,是用在51单片机上的.这也是我的课程计.望指教.-This is a simple microcontroller car Billing System is used in 51 of the MCU. This is my curriculum. Look exhibitions.

AT45DB021B的C51驱动程序-AT45DB021B driver of the C51

用485实现单片机之间的串行通信。 主机部分发送从机地址，等待从机响应，从机准备好就发数据,发完就接收从机的响应，接受成功就跳出循环，否则重发。-MCU with 485 Serial Communication between. Host of this address from the plane, waiting for the response from the plane, from the plane ready to discuss the data, finished on the reception of the response from the plane. set aside for recycling success, otherwise re-issued.

功能： 1、作为下位机采集8255数据并将此数据通过通讯送出， 2、采集数据为BCD，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-Features: 1, as under the 8255-bit machine data collection and communications sent through this data, 2, collected data for the BCD, first converted into binary, and then converted to deal with BCD 3, communication using methods 3, multi-machine communication, PC-fat address 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
