Internal temperature sensor

Hello.

I'm trying to use the internal temperature sensor, but I can't understand the reference manual formula:  Temp = ((V25 - Vsense) / Avg_slope) + 25).

In the product datasheet, it says V25 is 1.41 V and Avg_slope is 4.3 mv/�C. Must I use V25 and Vsense in mV or V? 

How can I do the conversion from the ADC Data register to Volts or mV?

Thank you.

Go to the STM32 forum for June 28 to get you answer.

Cheers, Hal

Hello Hal,

I am unable to find the page you have specified. Can you please help me with it?

I can't find it either. The Forum has had some problems tracking posts, so perhaps it went to the trash bin.

Try stm32f adc1 temperature dated July 20, 2012. If that doesn't provide what you need, post a request.

Cheers, Hal
