STC8A8K64S4A12单片机烧录程序成功却不执行程序

ID:303665 · 发表于 2019-4-10 15:16

例如点亮一个LED灯，给这个IO口低电平，但是LED不亮，测了IO口是高电平，程序给的是低电平。奇怪的是当断电的瞬间那个LED会闪一下，如果程序给这个IO口高电平（即让LED不亮），断电的瞬间LED不会闪一下，莫非是只有断电源的瞬间单片机执行了程序？

程序有问题。

程序有问题。

程序贴在上面了，主要功能是用单片机发送PWM让继电器动作然后通过ADC采样继电器是否接通

ID:303665 · 发表于 2019-4-10 22:07

为什么加了LCD1602显示的程序，单片机会不执行程序?

ID:734027 · 发表于 2020-4-20 23:59

楼主解决了嘛？我的也是这样的
