Question

求助STM8的TIM1的输入捕获问题

Answer 1

TIM1_EGR=0x01;//初始化TIM1TIM1时基初始化TIM1_EGR|=0x20;//重新初始化TIM1TIM1_PSCRH=0;//预分频设置PWM频率TIM1_PSCRL=0;TIM1_ARRH=0x0F;//设定重装载值TIM1_ARRL=0x9F;TIM1_CR1=0x80;//边沿对齐,向上计数,带缓冲TIM1_RCR=0x01;//重复计数器TIM1_CCMR2=0x68;//PWM模式1通道2PWM输出TIM1_CCER1=0x10;//高电平有效，开启输出TIM1_CCR2H=0;//设置占空比TIM1_CCR2L=0;。。。。。。通道1和3如此设置TIM1_BKR=0x80;//主使能TIM1_CR1|=0x01;//计数使能
