x2's... Check your pins!
Alas, I have found a flaw in my nifty custom boards I designed...
It seems that when I drew-up the main board, I used pin c.5 and c.6 for outputs to my motor controller to click the reverse relays on and off. Now that I am getting farther and farther into getting my 2 brains to talk to each other, I find that c.6 turns out to be a sweet-ass dedicated serial com line. It is the hserout/ hserin commands and is an awesome feature of the x2 parts. This is not a huge deal, I just have to scrape off a trace on the back and solder a jumper in but here is the lesson:
The Picaxe x2 parts are awesome but as you work with them, be sure you don't burn a bridge by using a "featured" pin inadvertantly.
