数据发送与接收模块源程序清单

CPU 工作频率最大不超过20MHz

本程序是利用Philips 公司的P87LPC764 单片机任何具有51 内核或其它合适的单片机都可在此

作为主控器的普通I/O 口(如P1.2/P1.3/P1.4)实现总线的功能对总线 上的器件本程序采用DS1302

进行读写操作命令字节在Command 传送字节数在ByteCnt 中所发送的数据在XmtDat 中所接收

的数据在RcvDat 中-Data source to send and receive a list of modules　CPU does not exceed the maximum operating frequency 20MHz This procedure is the use of Philips' s P87LPC764 single-chip with 51 cores or any other suitable single-chip can be used as the master of the ordinary I/O port (for example, P1.2/P1.3/P1.4) to achieve the functions of bus devices on the bus on the DS1302 for the use of this procedure to read and write operation to send the command byte in the Command in the number of bytes sent in ByteCnt XmtDat in the data in the data received in RcvDat
