Thanks Clive for the answer,
My code already with poll conversion, how can I separate ADC_result from CH0 and CH3 ?
ADC_raw = HAL_ADC_GetValue(hadc);
How can GetValue(hdc) CH0 and CH3 ?
currently I comment out one of the setting :
static void MX_ADC_Init(void)
{
ADC_ChannelConfTypeDef sConfig;
/**Configure the global features of the ADC (Clock, Resolution, Data Alignment and number of conversion)
*/
hadc.Instance = ADC1;
hadc.Init.OversamplingMode = DISABLE;
hadc.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV1;
hadc.Init.Resolution = ADC_RESOLUTION_12B;
hadc.Init.SamplingTime = ADC_SAMPLETIME_1CYCLE_5;
hadc.Init.ScanConvMode = ADC_SCAN_DIRECTION_FORWARD;
hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT;
hadc.Init.ContinuousConvMode = DISABLE;
hadc.Init.DiscontinuousConvMode = DISABLE;
hadc.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE;
hadc.Init.ExternalTrigConv = ADC_SOFTWARE_START;
hadc.Init.DMAContinuousRequests = DISABLE;
hadc.Init.EOCSelection = ADC_EOC_SINGLE_CONV;
hadc.Init.Overrun = ADC_OVR_DATA_PRESERVED;
hadc.Init.LowPowerAutoWait = DISABLE;
hadc.Init.LowPowerFrequencyMode = DISABLE;
hadc.Init.LowPowerAutoPowerOff = DISABLE;
if (HAL_ADC_Init(&hadc) != HAL_OK)
{
_Error_Handler(__FILE__, __LINE__);
}
/**Configure for the selected ADC regular channel to be converted.
*/
sConfig.Channel = ADC_CHANNEL_0;
sConfig.Rank = ADC_RANK_CHANNEL_NUMBER;
if (HAL_ADC_ConfigChannel(&hadc, &sConfig) != HAL_OK)
{
_Error_Handler(__FILE__, __LINE__);
}
/**Configure for the selected ADC regular channel to be converted.*/
//sConfig.Channel = ADC_CHANNEL_3; //comment out for reading only one ADC
if (HAL_ADC_ConfigChannel(&hadc, &sConfig) != HAL_OK)
{
_Error_Handler(__FILE__, __LINE__);
}
}
on the callback :
void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc)
{
if (__HAL_ADC_GET_FLAG(hadc, ADC_FLAG_EOC))
{
ADC_raw = HAL_ADC_GetValue(hadc);
// HAL_GPIO_TogglePin(OUT1_GPIO_Port, OUT1_Pin);
if(Index < 100)
{
// HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_SET);
ADC_Cplt = 0;
Value[Index] = ADC_raw;
Index++;
}
else
{
ADC_Cplt = 1;
// HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_RESET);
}
}
}
Any ideas ?
