Hello everyone,

I can't find the relative pin to the internal temperature sensor. Does anyone know which pin is it? Or should i only configure the TSON bit in the ADC_TRIGR1 register to wake up the temperature sensor?

In fact the problem rises also when i want to select the right channel on the adc.. Can anyone help please?

thanks a lot,

best,

Gilberto

Hello Gilberto!

No micro-controller pin is connected to the internal temperature sensor.

If you want to use it, you have to switch it on by setting the TSON bit in ADC_TRIG1.

When its wake-up time is elapsed (see the datasheet), the internal temperature sensor value can be read by setting the CHSEL_STS bit in ADC_SQR1 and by starting an acquisition.

Please, be informed that each temperature sensor must be calibrated.

See AN3397 ''Temperature sensor example using the STM8L-DISCOVERY board''.
