ADC and Asynchronous clock mode?

[Arman Ilmak]

Hi guys. I designed a simple PCB for measuring the battery voltage of a biomedical instrument. But I faced a simple problem. I use HAL to generate the code. So when I set the ADC clock in Asynchronous clock mode the while(1) is not executed!!!

IS it because of ADC interrupt happen too fast so the while cannot be executed?

Can you single step ?

where does it get stuck ?

code example ?

The help you get depends on the details you provide...

I can't even toggle a pin.

It gets stuck in the ADC callback function(The ADC is working properly, I mean that the MCU does not hang).

I don't know why I am not able to attach files.As soon as I can I will upload it.

Finally I could upload it.

void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc)

 {

     data=3.3*ADC_DIVIDER*HAL_ADC_GetValue(hadc)/4095;

}

should be 4096 ;

I dont use the interrupt call back,I use the DMA function, then when every I look at the data it is fresh...

   HAL_ADC_Start_DMA(&hadc, (uint32_t *)ADC_DMABuffer, ADC_ChannelCount);
