stm32 pwm CH1 CH1N

在提供的引用中，可以看到在stm32的代码中，通过修改TIM1的CCR寄存器的值来控制PWM输出的占空比。CH1通道用于输出PWM波，而CH1N通道用于输出高电平。但是根据引用[2]的描述，通过修改CCR寄存器的值与比较值时，CH1与CH1N无法同时达到不同的PWM波输出，只能同时输出相同或互补的PWM波。因此，在代码中TIM_SetCompare1()函数用于设置CH1通道的占空比，而TIM_SetCompare1N()函数用于设置CH1N通道的占空比。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
