HAL_ADC_Start(&hadc1);

HAL_ADC_PollForConversion(&hadc1,1000);

readValue1 = HAL_ADC_GetValue(&hadc1);

HAL_ADC_Stop(&hadc1);

HAL_Delay(100);

HAL_ADC_Start(&hadc2);

HAL_ADC_PollForConversion(&hadc2,1000);

readValue2 = HAL_ADC_GetValue(&hadc2);

HAL_ADC_Stop(&hadc2);

HAL_Delay(100);

HAL_ADC_Start(&hadc3);

HAL_ADC_PollForConversion(&hadc3,1000);

readValue3 = HAL_ADC_GetValue(&hadc3);

HAL_ADC_Stop(&hadc3);

HAL_Delay(100);




after executing this adc code the read values of readValue1, readValue2 and readValue3

are mutually reading the same value. i.e when i try to change the adc value of readValue3 with pot the other values are also changing

need help here...

thank you.

Show your ADC setup. Nothing wrong in the code you posted. Are the ADCs perhaps all looking at the same channel?
