英文这么说的 The workaround circuits take advantage of the one thing that locked conditions have in common: the red LED stays illuminated. The basic idea of the circuits is to detect the red LED staying on for a period of time and then to issue a manual reset to the voltage monitor IC that drives POR after an appropriate amount of time has elapsed
我认为意思是,这个电路是这样的情况,死锁的时候红灯是一直亮着的,所以只要灯一直亮着那就会引起一次por的重启,但是我不明白这个电路的原理是什么,怎么实现的“灯亮一段时间重启”??网明白的人告诉下 |
