WebOct 22, 2024 · Oct 22, 2024 at 19:35 The temperature is read internally by ADC. The issue is when they are used together. If I dont use HAL_I2C_Master_Receive in the interrupt callback the temperature is around 35C as expected. But when I use HAL_I2C_Master_Receive the temperature swings from 35C to 145C. Webissue - The ADC_CHANNEL_VBAT and ADC_CHANNEL_TEMPSENSOR channels are shared so only one can be used at a time. If you want to use both, you will need to swap between the two. When swapping from VBAT to TS, the VBAT flag remains enabled in ADC->CCR causing ADC_CHANNEL_VREFINT to read unexpected values.
