DJ, Are you writing code for the Dallas 1-wire protocol? Neat.
I cheated.
I used a PICAXE for my heat pump (Oz-talk for HVACs?) until I get to
develop PIC-level code. I want to talk to 3x Dallas Temp sensors & soft
start my duct fan (phase controlled start of a MOC30xx-coupled triac).
Sigh, as usual, THe S/S+N ratio in my life is too high, & I will live
with the PICAXE for another year or so.
