Re: The way forward

I'd really like to support this project, it is the most evolved project i know in this area.

Sadly my programming knowledge is completely outdated to 30 year old BASIC and FORTRAN programming..

But if i can help in any way, documenting or such, i will do.

This project is worth it.

Re: ESP Easy next stable... (release candidates)

Hello,

this may depend on your WiFi AP too.
I'm using a single Ubiquiti Unifi AC-Pro at home and three at my company - they cover quite a big range.
These are quite expensive, but using "small" or cheap AP's showed me decreased connectivity and speed.

If it can resolve 3.3V or if everything above 1V is maxed out to 1023 is on another note.

So i don't see how the map calculation for 5 (or 3.3) volts to 1024 steps should work.
