Re: ESP32 ADC Non-linear Issues - How do I fix / change Attenuation or width?

Interesting.
You compare actual to ESP32 above. What was being compared?

What are you using to determine actual temperature and humidity?

Interesting, it never occurred to me that he wasn't calling the functions - that would definitely explain it.

Re: ESP32 ADC Non-linear Issues - How do I fix / change Attenuation or width?

Maybe you need a newer version of Arduino core?

I find the versioning of this stuff confusing, at best.

Re: ESP32 ADC Non-linear Issues - How do I fix / change Attenuation or width?

Those calls seem to work for me. Note: there's been plenty of discussion of non-linearity of the ADC.

Re: ESP32 ADC Non-linear Issues - How do I fix / change Attenuation or width?

The big question - did tweaking these settings achieve the desired ADC behavior?

Re: ESP32 ADC Non-linear Issues - How do I fix / change Attenuation or width?

What a coincidence! That's EXACTLY the same ESP32 I use. I've got two, they work perfectly (so far?) Width: /* * Set the resolution of analogRead return values. Default is 12 bits (range from 0 to 4096). * If between 9 and 12, it will equal the set hardware resolution, else value will be shifted. * ...

Re: Strange Interrupt behavior on IO

I wonder if using Serial.print() in the ISR is causing the problem?

Re: compiling bme280 from yanbe

That's a fine solution. Or, you could experiment with with changes to the compiler command, probably in a makefile or config file, to ignore this error.

Re: Unable to receive TCPIP-packets with wifi callback function

select() has a timeout argument which can be used to set no block, block until timeout, or block forever.
