Calibrating the STM32F334 ADC

Page last updated 17 May 2015, by Jose Luu. 0 replies

class OpenAnalogIn: public AnalogIn { public: OpenAnalogIn(PinName pin) : AnalogIn(pin) { }; analogin_t * getADC() { return &_adc; }; };

OpenAnalogIn firstVoltageADC(A0);

void setup_ADC() {

ADC_HandleTypeDef AdcHandle; Calibrate ADC AdcHandle.Instance = (ADC_TypeDef *)(firstVoltageADC.getADC()->adc); HAL_ADCEx_Calibration_Start(&AdcHandle,ADC_SINGLE_ENDED); }

then use (as usual)

float firstVoltage=firstVoltageADC.read();
