Hi,
I have configured ADC like
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_ASYNC_DIV2;
hadc.Init.Resolution = ADC_RESOLUTION_12B;
hadc.Init.SamplingTime = ADC_SAMPLETIME_7CYCLES_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 = ENABLE;
hadc.Init.LowPowerFrequencyMode = ENABLE;
hadc.Init.LowPowerAutoPowerOff = ENABLE;
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_9;
sConfig.Rank = ADC_RANK_CHANNEL_NUMBER;
if (HAL_ADC_ConfigChannel(&hadc, &sConfig) != HAL_OK)
{
_Error_Handler(__FILE__, __LINE__);
}
/* Select PCLK/4 for ADC clock if CKMODE[1:0]=00 as HSI16 */
SET_BIT(ADC1->CFGR2,ADC_CFGR2_CKMODE_1);
My MCU is in Low power Run mode.
In Low power run mode ADC not working..
but i have resume Low power run mode that time is work..
/*Disable the Low Power Run mode For ADC*/
HAL_PWREx_DisableLowPowerRunMode();
/*ADC Initialization*/
MX_ADC_Init();
/* Get the Battery Perc */
Get_Battery_Status(); //ADC conversion done here
/*Disable the Low Power Run mode*/
HAL_PWREx_EnableLowPowerRunMode();
/*Disable ADC*/
HAL_ADC_MspDeInit(&hadc);
This scenario okay or not ?
My MCU system clock is MSI = 65.536 KHz
