Hal time pwm

WebFor the HAL issue, it seems it was my fault: I accidentally disabled the input channel before calling HAL_TIM_PWM_Stop(), so the HAL saw only one channel and then disabled the timer. ... What I do know is that PWM mode attempts to reset the CNT register when it matches the time channel's CCR register (i.e. the PWM period). That is how PWM works. WebDec 22, 2024 · Functions. HAL_TIMEx_PWMN_Start ( TIM_HandleTypeDef *htim, uint32_t Channel) Starts the PWM signal generation on the complementary output. Stops the PWM signal generation on the complementary output. Starts the PWM signal generation in interrupt mode on the complementary output.
