关于无法进入串口中断的一些问题 |
10金钱
最佳答案串口两根线,发送和接收,你的外部中断是用串口往外发送,走发送线,你的串口配置的接收非空中断即接收中断,当你发送的时候接收线上可没有数据,不会产生接收中断。你的程序在外部中断发生的时候绝不会进去串口接收中断的,除非你配置发送完成中断才会在发送完成后进入中断

He who fights with monsters should look to it that he himself does not become a monster, when you gaze long into the abyss, the abyss also gazes into you.
过于执着就会陷入其中,迷失自己,困住自己。 |
