Happy Christmas all
Well I got Slothie's Pi key interface board wired up and working - didn't have a Pi zero around so used an ordinary Pi and built the wire interface. It works great, although the network cable does run across the top of the MK14 at present.
Having got that working I wondered
if I could take the web interface that I'd built for the ESP8266 and use it on the PI.
Well the answer is yes I could. Using the lighttpd web server, brushing up on my HTML, CSS, Javascript, PHP, Python and working out how AJAX interface works, I have found it possible to control the MK14 keyboard from a web page on the PI. Why does it take so many different languages etc., to get the websites to work.
Hopefully I can get the code tidied up, documented, and up on github in a few days.
Cheers
David
