stm32f030C8T6 pwm OUT

The STM32F030C8T6 microcontroller has several timers that can be configured to generate PWM signals on their output pins. Here is an example code snippet in STM32CubeIDE that configures Timer 3 to generate a PWM signal on pin PB1:

/* Enable the clock for Timer 3 and GPIOB */
__HAL_RCC_TIM3_CLK_ENABLE();
__HAL_RCC_GPIOB_CLK_ENABLE();

/* Configure PB1 as alternate function mode */
GPIO_InitTypeDef GPIO_InitStruct = {0};
GPIO_InitStruct.Pin = GPIO_PIN_1;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
GPIO_InitStruct.Alternate = GPIO_AF1_TIM3;
HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);

/* Configure Timer 3 to generate PWM signal on PB1 */
TIM_HandleTypeDef htim3 = {0};
htim3.Instance = TIM3;
htim3.Init.Prescaler = 0;
htim3.Init.CounterMode = TIM_COUNTERMODE_UP;
htim3.Init.Period = 1999; // PWM frequency = 72 MHz / (Prescaler * (Period + 1))
htim3.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;
HAL_TIM_PWM_Init(&htim3);

TIM_OC_InitTypeDef sConfigOC = {0};
sConfigOC.OCMode = TIM_OCMODE_PWM1;
sConfigOC.Pulse = 1000; // PWM duty cycle = Pulse / (Period + 1)
sConfigOC.OCPolarity = TIM_OCPOLARITY_HIGH;
sConfigOC.OCFastMode = TIM_OCFAST_DISABLE;
HAL_TIM_PWM_ConfigChannel(&htim3, &sConfigOC, TIM_CHANNEL_4);

/* Start the PWM generation */
HAL_TIM_PWM_Start(&htim3, TIM_CHANNEL_4);

This code configures Timer 3 to generate a PWM signal with a frequency of 36 kHz (72 MHz / (1 * (1999 + 1))) and a duty cycle of 50% (1000 / (1999 + 1)) on pin PB1. You can change the frequency and duty cycle by adjusting the `Period` and `Pulse` values in the code.
