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);
}
