Question
"While" does not work when ADC DMA is enabled
I am starting to experiment with stm32f411vet6 (discovery), looking forward to learn and help.
On Live Expressions (Debug by STM32CubeIDE, I choose to run by Resume).
Without a code "HAL_ADC_Start_DMA(&hadc1,(uint32_t*) &ADC_Value, 1);" : The program works and "Count_While" works right!
However, when the code is available "HAL_ADC_Start_DMA(&hadc1,(uint32_t*) &ADC_Value, 1);" : The value of "ADC_Value" is always constantly updated, but "Count_While" stops at the value of 1. I try to run with "Step Over" then: I can't continue "Step Over" after running the code: "HAL_Delay(500);". My program is stopped here! So what are the fault possibilities?
Thanks!
uint16_t Count_While = 0;
uint16_t ADC_Value;
int main(void)
{
HAL_Init();
MX_GPIO_Init();
MX_DMA_Init();
MX_ADC1_Init();
HAL_ADC_Start_DMA(&hadc1,(uint32_t*) &ADC_Value, 1);
while (1)
{
Count_While ++;
HAL_Delay(500);
}
}
