8031是目前最常用的单片机.笔者在调试中发现在8031编程中有几个问题易被疏忽而导致错误.现提供给读者参考.1.8031内部CTC定时/计数器这是加法计数器.因此在每次定时中断溢出时,必须重新设定时间常数.按习惯,是在中断服务程序中,先送低字节,后送高字节.例如对CTC_0,在中断服务程序开始应执行指令: 8031 is the most commonly used microcontroller. I found in the debugging process in the 8031 ​​programming a few problems easily lead to errors are ignored. Now available to readers reference .1.8031 internal CTC timer / counter This is the addition counter. Therefore, at each timing Interrupt overflow, you must reset the time constant. By convention, in the interrupt service routine, first send low byte, post high byte. For example, CTC_0 interrupt service routine should be executed at the beginning of the instruction:
