MCS
MCS-51单片机有5个中断源,其中两个是由-INT0、-INT1引脚输入的外部中断源;另外三个是内部中断源即由T0、T1的溢出引起中断和串行口发送完一个字节或接收到一个字节数据引起中断。触发外部中断有两种方式,即下降沿引起中断或低电平引起中断。当编程TCON中的ITi(i=0、1)为1时,则引起触发的方式为边沿触发方式,反之(ITi=0)为低电平触发方式。每个中断源的中断请求能否得到响应要受两级“开关”的控制,即一个总“开关”-MCS-51 single-chip has five interrupt sources, two of which are by-INT0,-INT1 pin input external interrupt source the other three internal interrupt sources from the T0, T1 overflow caused by the disruption and serial port sending or receiving end of a byte to a byte of data caused by interruption. Triggered external interrupt has two modes, namely, falling edge or low-level disruption caused disruption caused. When programming TCON in ITi (i = 0,1) for the 1:00 has been the subject of a way to trigger the way to the edge of the trigger, on the contrary (ITi = 0) for low-level trigger mode. Each interrupt source interrupt request can be subject to levels in response to

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
