PIC16887A单片机一个双机通信，2个单片机异步串行通信接口相连方式为：RX和TX交叉对接，左边的单片机U1，每按下按键S1就发送一个字节数，从0x20开始发送，每送一个数据，此数加1.发送的同时在D口上输出。右边单片机U2为接收状态，采用中断方式，如有接收中断，则进入中断，将接收到的数直接在D口上输出-PIC16887A a two-machine communications microcontroller, two asynchronous serial communication i

PIC16887A单片机单片机U1为主控发送,从动接收,U2为从动接收,产控发送的双机通信:开始时,由U1担任主控方,向从动方U2发送字符”hello!”,发送完毕并转为同步从动接收状态,如接收到的字符为”How are you?”则LED闪亮,通信结束.U2开始时被设置为同步从动接收状态,收到7个字符并确认接收的字符为”hello!”后,再转为主控发送方式,回送字符”How are you?”,进入LED闪亮状态,通信结束-U1 is the master SCM SCM PIC16887A

PIC16887A单片机主控发送接收,与从动接收发送的双机通信,和上例一样,不管接收还是发送U1始终为主控方,U2始终为从动方,过程和上例一样-PIC16887A master microcontroller sending and receiving, sending and receiving the double slave communication, and, like the example above, whether received or sent is always the
