Just had a Idea.
If the lighting controler, is to be a zone controler and do other
things perhaps we should off load some of the work to a PIC.
My worry is that we may overload the Rabbit, Untill i give it a try i
dont know how much overhead the tcp/ip operations will take up.
clearly phase control on multiple chanels is time critical, I am
going to have a go but we might have to let a PIC do the phase
control. If we have to go down that route it will not make much
difference to the cost but it will increace the footprint of the
board.
It may not be needed, we will see.
On another point, I was thinking of 4 dimable channels and 4 on/off.
Should the hardware controler have all this on board, or should the
drive circuits/protection relay be daughter boards, so that if you
only want a two channel device you dont have to pay for redundant
parts. Also since its these parts which are likley to be the ones
which get hammered.
John.
