As promised, I've uploaded the ESP8266 version here. You will need an MCP23071 I/O expander chip for this one (see previous log).

Although the version in the archive targets an Adafruit Huzzah ESP8266 board specifically, the target can easily be changed to another ESP8266 board or anything that has an I2C bus and a PlatformIO target.

As some point I'll convert the software to an Arduino library. As there are multiple ways to interface to the hardware (GPIO pins, I/O expander chip), I think I'll need to need to split the code across two libraries in the same way that the Adafruit TFT libraries work: a low level library that accesses the hardware and a high level one for the keyboard handling code that's independent of the hardware access method. This is something for later though.
