1. Configure Clock And DAC

Note up clock to 216 Mhz in clock configuration


2.Generation Source and edit code

In Src/main.c

int main(void)
{
  HAL_Init();
  SystemClock_Config();

  MX_GPIO_Init();
  MX_DAC_Init();

  HAL_DAC_Start(&hdac, DAC_CHANNEL_1);
  HAL_DAC_Start(&hdac, DAC_CHANNEL_2);
float i=0.0;
  while (1)
  {
    i+=1;
    if(i>2047){
        i=0;
    }
      HAL_DAC_SetValue(&hdac, DAC_CHANNEL_1, DAC_ALIGN_12B_R,(int)(2048*(1+sin(i/4095*4*3.14))));
    HAL_DAC_SetValue(&hdac, DAC_CHANNEL_2, DAC_ALIGN_12B_R,(int)i*2);
    HAL_Delay(1);
  }

}
