I just tested it again but with the firmware 2.1.0. It works on pin 1, 2 and 10. I think there is a bug in the firmware 2.1.9....

@kuriko
I have tested it with 1, 2 and the battery pin 10 always the same error.

@kuriko
Yes, 2.19

Hey,

I'm trying to use the ADC module on the Cardputer and I keep getting this error:
File "<stdin>", line 18, in <module>
File "<stdin>", line 11, in setup
OSError: (-261, 'ESP_ERR_NOT_FOUND')

What am I doing wrong?
Thank you very much
