Hall sensor
Hall sensor
The https://www.espressif.com/sites/default ... ual_en.pdf mentions an inbuilt magnetic field sensor on P623. Does anyone know if it's accessible via upython?

But it is not very sensitive.

Re: Hall sensor
Do you know a way to open the hall switch in fig146 & connect pad_in[7:0] to the low noise amp instead? Would the amp be any good for thermocouples or is the hall insensitive because the amp is crap?

Sorry, I do not know that.

Re: Hall sensor
Thermocouples need a specialised interface because the voltage they produce is tiny. They also need cold junction compensation. See this example board.
