Hi Tony

I plan to use a PIC to give me dimming and on/off control of my LED's.
It
will also have an RS485 interface for serial connection so the good old
home control systems can talk to it. You never know but it is likely it
will use the xAP protocol I am currently coding for the relay board
controller. This is a high priority project as SWMBO said so and the
evenings are closing in - there is no light in the cupboard at the
moment.
It won't do the current matching etc. of the Maxim chip but for most of
us
this won't be a problem. I was thinking of around 15 brightness levels
but
this is something I will have to play with as maybe more or less will
be
needed.
