Nick Johnson over at Arachnid Labs posted an update on his uCAN- a protocol stack for microcontroller networking we posted previously:
First working uCAN hardware! It’s not much to look at, but it is fully functional! A power injector with a 12v wall wart, a Raspberry Pi with uCAN expansion board, and an Arduino Uno with uCAN shield, connected together into the first fully functional uCAN network – at hardware level, at least. :)
A simple Arduino program sends incrementing 4 byte packets at 100 kilobits
