How to enable on-board temperature sensor on STM32G491

2023-06-08
On STM32G491 (and family) MCUs the on-board temperature sensor can be read by ADC1 or ADC5 to provide junction temperature.RM0440 Rev 7 informs us:In order to read the temperature sensor we must "wake" it from power-down mode by setting the VSENSESEL...

Getting temperature from STM32G491x internal temperature sensor ADC

2023-06-06
How to get temperature (degC) from the STM32G491x internal temperature sensor?I have my ADC working and producing raw count values. Eg: 303.So assuming a working voltage of 3V3 and maximum count value of 4095 then I assume that I must multiply the ra...

Unable to TX on NUCLEO-ST32G491RE FDCAN1
