Any help is appreciated!
Could you have a try with the latest ESP8266_NONOS_SDK?
Thanks for your interest in ESP8266!
Faye, same problem, same offset. I'll try on more boards, but I got 50% working and 50% with this problem and I'm always checking the voltage at the pin with a calibrated equipment to be sure.
Things i've tried:
Switched the ESPs between boards to to be sure that isn't the circuit, the problem followed the ESPs.
Wrote a simple code using system_adc_read_fast(), wifi off and got the same result, with the ADC pin grounded it reads 10-12 points.
Yesterday I've built 3 more boards, 2 ok and 1 with this offset. I have now 3 with offset and 4 working.
Don't know what's going on;
