stm32的HAL库中存在的BUG

1.STM32Cube FW_F1 V1.8.0 的stm32f1xx_hal_tim.h 中1744行的宏定义

#define TIM_RESET_CAPTUREPOLARITY(__HANDLE__, __CHANNEL__) \
(((__CHANNEL__) == TIM_CHANNEL_1) ? ((__HANDLE__)->Instance->CCER &= ~(TIM_CCER_CC1P | TIM_CCER_CC1NP))):\
((__CHANNEL__) == TIM_CHANNEL_2) ? ((__HANDLE__)->Instance->CCER &= ~(TIM_CCER_CC2P | TIM_CCER_CC2NP)) :\
((__CHANNEL__) == TIM_CHANNEL_3) ? ((__HANDLE__)->Instance->CCER &= ~(TIM_CCER_CC3P)) :\
((__HANDLE__)->Instance->CCER &= ~(TIM_CCER_CC4P)))

红色部分多了一个括号
