通讯规则: 1:时钟7.3728 MHz/波特率9600/9个数据位/奇校验/1个停止位/硬件多机通讯功能/ 2:通讯连接采用硬件MAX485,双向单工 3:每个上行/下行的数据包的字节个数都是一样的(通讯数据量) 4:每个上行/下行的数据包都采用CRC8校验 5:数据接收采用中断+查询的方式 6:总是由主机向从机发送一个数据包,从机收到数据包后向主机回复一个数据包 7:不管是主机还是从机,如果收到的数据包有任何错误,都将丢弃该数据包,等效于没有接收 8:从机之间不能相互通讯,必须通过主机才能交换数据 9:无效地址是0,主机地址是1,从机地址是2.3.4......广播地址是255 -err

freescale单片机串行通讯程序,数据包方式，支持数据发送正常检验,并可使用命令实现对片机FLASH的读、写和擦除功能。-Freescale MCU serial communications, data packets, sends the data to support normal testing and can be used to achieve an order-of-FLASH read, write and erase functions.
