使用3根普通IO通讯
不使用中断
双方都可以主动发起数据通讯,也都可以被动接收数据,即可以对等传输.
有发送和接收的检查等待机制,发送方知道对方什么时候收了数据,接收方知道发送方什么时候发了数据.
无需进行数据延时,最大可能地加快了通讯速度.
CPU闲的时候通讯速率可以最快.忙的时候又可以无限等待.保证绝对同步,不会出错.
双方CPU工作速度可以任意,即使是51和P4通讯,也能保证正确无误.-3 IO communication does not use interrupts both sides can initiate data communications, also can passively receive data, that is, can transfer send and receive check wait mechanism, the sender know each other when closing the data, receive aware of the sender when the data no data delay, the maximum possible speed up the communication speed can be the fastest CPU idle, when the communication rate. busy time and can wait indefinitely to ensure absolute synchronization, can not go wrong. CPU operating speed can be arbitrary, even if it is 51 and P4 communications, but also to ensure the correct
