帮忙啊“C51 为什么我两个定时器不能同时一起用”？？

请教各位老师，我在上面的程序中，如果把两个定时器中断打开，它怎么仅运行第一个，我一个一个的用它都能用运行且正常，现我想两个都要用上，而且一起用，请问我上面的程序怎么改？？

              望指教！！！

8 个解决方案

#1

void timer1(void)interrupt 2 using 1
改为：
void timer1(void)interrupt 3 using 1

定时中断1的中断入口号是3

#2

大问题被楼上的说了，偶看到个小问题：
#include "AT89x051.H"
怎么说文件名也该是：AT89x51.H

#3

路过

#4

ATMEL 也有 AT89C2051型号的，所以也会有 #include "AT89x051.H"

#5

恩，多谢指教：）

#6

瞧瞧

#7

最好认真的看看书

#8

问题已被指出！
我只好说说debug的方法！在调试时你可以在中断向量处设置中断呀，看程式有没运行至此呀！如果这样的话像这种问题应该很快就查出来了！
