Hi,Im new to STM and trying to use ADC with DMA in circular mode but the value of my ADC remains at 0. I also tested it with Polling, which works.ICache and DCache : Enable
void menu_adc(void)
uint32_t adc_buffer[1];
uint16_t adc0;
uint8_t flag_adc;
void menu_adc(void)
{
char buf[30];
HAL_ADC_Start_DMA(&hadc1, adc_buffer, 1);
while(1){
if (flag_adc == 1)
{
flag_adc =0;
int len = snprintf(buf, sizeof(buf), "ADC0: %u\r\n", adc0);
HAL_UART_Transmit(&huart1, (uint8_t*)buf, len, HAL_MAX_DELAY);
HAL_Delay(200);
}
if (HAL_ADC_PollForConversion(&hadc1, 100) == HAL_OK)
{
uint32_t adc_value = HAL_ADC_GetValue(&hadc1);
int len = snprintf(buf, sizeof(buf), "ADC0: %lu\r\n", adc_value);
HAL_UART_Transmit(&huart1, (uint8_t*)buf, len, HAL_MAX_DELAY);
}
}
}
void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc)
void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc)
{
if(hadc->Instance == ADC1)
{
adc0 = adc_b
