Hello guys

I suffocate in a water glass.

My program enters in the ADC Interrupt but I can´t reset EOC flag. What is the matter with my code?
void ADC_IRQHandler(void)
{
IT_tick=1;
ADC1ConvertedValue = ADC1->DR; /* Dato convertido */
ADC1->SR &=~ 0x0000001F; /* DOESN´T WRITES SR */
/* ADC_ClearITPendingBit(ADC1, ADC_IT_EOC); */ /* DOESN´T WRITES SR EITHER*/


}

Which microcontroller?

Oh sorry, i´ve forgotten to type it.

SMT32f103VE

It seems that it is unwrittable or something like that, althought in Reference manual says that reading ADC1 DR (Data register) clears the EOC flag. I´ve tried it and I´ve tried to clear the flag directly too but I couldnt.

I haven't use the ADC in STM32 so can't give you an answer.
One thing you can try is to post your question on the STM32 forum:

Hope this helps.
