但定时中断一直能正常运行，启动ADC，
void TIM2_IRQHandler(void)
{
static INT16U count = 0;
if (TIM_GetITStatus(TIM2, TIM_IT_CC1) != RESET)
{
TIM_ClearITPendingBit(TIM2, TIM_IT_CC1);
ADC_SoftwareStartConvCmd(ADC1,ENABLE);
// Start ADC1 Software Conversion
capture = TIM_GetCapture1(TIM2);
TIM_SetCompare1(TIM2, capture + TimerCount_500);
}
else if (TIM_GetITStatus(TIM2, TIM_IT_CC2) != RESET)
{
TIM_ClearITPendingBit(TIM2, TIM_IT_CC2);
capture = TIM_GetCapture2(TIM2);
TIM_SetCompare2(TIM2, capture + CCR2_Val);
}
else if (TIM_GetITStatus(TIM2, TIM_IT_CC3) != RESET)
{
TIM_ClearITPendingBit(TIM2, TIM_IT_CC3);
capture = TIM_GetCapture3(TIM2);
TIM_SetCompare3(TIM2, capture + CCR3_Val);
}
else
{
TIM_ClearITPendingBit(TIM2, TIM_IT_CC4);
capture = TIM_GetCapture4(TIM2);
TIM_SetCompare4(TIM2, capture + CCR4_Val);
}
}

有没问题不知道，但效率确实比IO模拟的高太多了

希望有高说做进一步的解释。

我改为char a[]="是";
char qh = 0, wh = 0;
//每个汉字，占两个字节, 取其区位号
qh = (a[0]/94) + 0xa1; //获得区码
wh = (a[1]%94) +0xa1; //获得位码
当输出qh，wh时还是地址，并不是区位码。
我改的对吗？

谢谢哈~就是这个解决方案，问题已解决~~

我想是焊接造成。主要原因铬铁带感应电（用万用表测试铬铁交流5VAC~18VAC）。我铬铁接地及上电焊后一样。当不接地只拔除铬铁电源后焊接大有改善。我想了解下NXP的是否一样？

简单的八位单片机就可以,还不需要操作系统.

买个USB的调试工具,也不贵的

因为你的是移植了ucos-ii,所以ISR不要那个__irq.....

引用 3 楼 zyzhang365 的回复:
晕！
在中断里面计数就可以了。
假如你中断周期是100ms，如果你需要1000ms（1s)的定时，那么在中断中软件计数10次就可以了。
具体的楼主可以算算。
我用的也是这种方法

用微软的肯定是这样的，要想有特色，自己找个懂ps的帮你画图，你直接在程序里bitblt
