This repo has the source code for the ESP8266 firmware which is provided with the AnalysIR software, minimally modified to work with PlatformIO and the latest ESP8266 Arduino core

To be specific, on line #29, #include <Arduino.h> was added, as PlatformIO requires that.

In addition, on lines #39-40, the code was modified to include ICACHE_RAM_ATTR because without that, the program crashes repeatedly upon first starting up. More info here

Finally, the setup() and loop() functions were moved to the end of the program, to compile properly using PlatformIO. Everything else remains the same.

If you'd like to change the pin definitions, see lines #43-44.

You may still receive an error message Error on Serial Port: Frame in AnalysIR (I do) - this can be ignored.

This repo is mainly because I keep modifying this program, forgetting how I did it, and re-doing all of these steps. But I thought I'd make it public in case it helps somebody else.
