Simple method for setting PWM duty cycle on the STM32 (HAL)

setDutyCycle.cpp

static void setDutyCycle(TIM_HandleTypeDef* const htim, uint32_t channel, float duty_cycle) {
	if (duty_cycle > 100) duty_cycle = 100;
	if (duty_cycle < 0) duty_cycle = 0;

	float pw_resolution = (((float)(*htim).Init.Period + 1.0f) / 100.0f);

	uint16_t pw_desired = pw_resolution * duty_cycle;
	__HAL_TIM_SET_COMPARE(htim, channel, pw_desired);
}
