The truly minimalistic keyboard is now in place. It is not so hard to figure out wich button to press.

I hooked up the Zigbee module and got it running fairly easy. I am using the receiving port of the same serial port that runs the display. Of course the speed was wrong and I got some unrecognized characters at the beginning.
Now I will probably go for the mechanical assembly with a little help from some epoxi glue.

I have given up the pervasive displays for some time and is moving towards a minimalistic design with a small oled I used before.
The interface is very simple with only 3 wires.
