2019年08月21日 | STM32F103ZET定时器TIM1输出六路带死区互补PWM波形

使用默认引脚输出6路PWM，#define FullRemap_TIM1则重映射 PIN脚；

遗留问题：调用TIM_CCxNCmd(TIM1, TIM_Channel_X, TIM_CCx_Enable);导致互补PWM无输出。

TIM_CCxCmd(TIM1, TIM_Channel_X, TIM_CCx);确可以正常开关PWM输出；

遇到问题：PA8、10、PB13、14、15均有输出，PA9无输出；

问题解决：虽然没初始化UART1模块，但打开RCC_APB2Periph_USART1时钟导致；
