Timer0停止计数
芯片是STC8H3K64S4，30M时钟，定时器0是2mS，运行几分钟以后定时器0就停止计数了，程序和定时器0无关的部分正常运行。定时器0是用在按键和OLED刷新，所以出现故障很明显。
但是都是，如果在循环里任意一个地方读TR0，定时器就能继续计数。
那位知道这是神马原因？

你的程序有缺陷，你把你的代码完整地贴上来看看
目前已知：ADC中断如果不开启中断嵌套（494行）就不会导致这个问题 jeff.c 发表于 2023-6-1 13:25
目前已知：ADC中断如果不开启中断嵌套（494行）就不会导致这个问题
那估计你的中断程序有问题，仔细检查。
用这个范例试下：
没有看见这个程序 Timer0Init(); STC32G12K128 发表于 2023-6-1 16:02
用这个范例试下：
是的，平时都是用STCISP工具配置的定时器
void Timer0Init(void) //2毫秒@30.000MHz
{
AUXR &= 0x7F; //定时器时钟12T模式
TMOD &= 0xF0; //设置定时器模式
// TL0 = 0x3C; //设置定时初始值 //1mS
// TH0 = 0xF6; //设置定时初始值
TL0 = 0x78; //设置定时初始值 //2mS
TH0 = 0xEC; //设置定时初始值
TF0 = 0; //清除TF0标志
TR0 = 1; //定时器0开始计时
ET0 = 1;
//IP &= 0xfd;
//IPH &= 0xfd;
} 那估计你的ADC中断程序运行超过两毫秒。你需要调整一下。 本帖最后由 pingfr 于 2023-6-2 11:41 编辑
我的STC32G12K也遇到类似问题，开timer0中断后进入一次就再也不进了，配置也没啥特殊的
