Hi Guyzz
Does anyone have a schematic of the Betty ?
I'm quite sure i saw a user on http://www.mikrocontroller.net/ pasting a part of a schematic.
I was wondering if it was public available ?
TIA

I havent seen any schematic around. But you can deduct most things from the Pinout description of the LPC2220 on the Bettyhacks wiki page.
The IR receive has some operational amplifier/comparator to shape the receive signal going to the processor pin.
If someone really has a schematic, great, post your work here!
