Dear,
I start a project with CubeMX for the first time and I need to use ADC.
I configure ADC1 IN1 to do this.
I use HAL_ADC_START_IT to launch the continuous conversion and have an interrupt when the conversion is finish. I get in HAL_ADC_ConvCpltCallback only one time and after I have HAL_ADC_ERROR_OVR in ADC state.
ADC initialization :
void MX_ADC1_Init(void)
{
ADC_ChannelConfTypeDef sConfig;
/**Configure the global features of the ADC (Clock, Resolution, Data Alignment and number of conversion)
*/
hadc1.Instance = ADC1;
hadc1.Init.ClockPrescaler = ADC_CLOCKPRESCALER_PCLK_DIV8;
hadc1.Init.Resolution = ADC_RESOLUTION12b;
hadc1.Init.ScanConvMode = DISABLE;
hadc1.Init.ContinuousConvMode = ENABLE;
hadc1.Init.DiscontinuousConvMode = DISABLE;
hadc1.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE;
hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT;
hadc1.Init.NbrOfConversion = 1;
hadc1.Init.DMAContinuousRequests = DISABLE;
hadc1.Init.EOCSelection = EOC_SINGLE_CONV;
HAL_ADC_Init(&hadc1);
/**Configure for the selected ADC regular channel its corresponding rank in the sequencer and its sample time.
*/
sConfig.Channel = ADC_CHANNEL_1;
sConfig.Rank = 1;
sConfig.SamplingTime = ADC_SAMPLETIME_3CYCLES;
HAL_ADC_ConfigChannel(&hadc1, &sConfig);
}
Is it an error of CubeMX or STM32F4 (didn't see something in errata sheet) or I did a mistake ?
