WebJun 23, 2015 · It looks like your code has 2 interrupt routines. One for Int0 at interrupt vector 03H and one for Timer 0 at interrupt vector 0BH. I see that in main you enable global interrupts, but I don't see interrupts enabled for timer 0 or external interrupt 0 (SETB ET0 or SETB EX0). Also, you may need to clear the interrupt flags in your service routines. brady white statsWeb一设计题目:直流电机调速二设计思路1. 问题的提出能否以单片机现有资源模拟调整直流电动机的转速.2. 分析问题的功能1 .在P1.0引脚输出低频脉宽调制信号PWM,PWM信号的脉冲占空比脉动电压的高电平时间占周期比可以通过和P1 连接的按_文件跳动filedance.cn brady white on black
