Reading the temperature sensor of an STM32H753 When reading the temperature sensor of an STM32H753, I read above 65 °C, right at start-up. The board lays on the desk, and the MCU doesn't feel that warm, maybe up to 36 °C.The environmental temperature now, is about 24 °C.After a some time, the MCU temperature increases to above 85 °C. The reading seems somewhat high, to me. Below is the code I used.Update: I added the call to the ADC calibration function.HAL_ADCEx_Calibration_Start(&hadc3, ADC_CALIB_OFFSET, ADC_SINGLE_ENDED);Below updated code, which now reads reasonable values:#define TS_CAL1_REG 0x1FF1E820 // Calibration ADC value at 30 °C
#define TS_CAL2_REG 0x1FF1E840 // Calibration ADC value at 110 °C
#define TEMPERATURE_ADC_SAMPLES 8
uint16_t MCU_Temperature_AVG = 50;
uint16_t TemperatureCalculate(uint32_t ts_data)
{
// 0x1FF1E820 Calibration ADC value at 30 °C = 0x2fc0, 12224
uint16_t ts_cal1 = *(uint16_t*) (TS_CAL1_REG);
// 0x1FF1E840 Calibration ADC value at 110 °C = 0x3cb4, 15540
uint16_t ts_cal2 = *(
