CH32 Oscillator

In order to get to know the CH32V307 MCU better I decided to create a dual oscillator using the DACs.

Timer

void Timer4_Init (void) {
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure = { 0 };
    RCC_APB1PeriphClockCmd (RCC_APB1Periph_TIM4, ENABLE);

    TIM_TimeBaseStructInit (&TIM_TimeBaseStructure);
    TIM_TimeBaseStructure.TIM_Period = 3000 - 1;
    TIM_TimeBaseStructure.TIM_Prescaler = 0;
    TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit (TIM4, &TIM_TimeBaseStructure);

    TIM_SelectOutputTrigger (TIM4, TIM_TRGOSource_Update);
    TIM_Cmd (TIM4, ENABLE);
}
