00022     Usage and assumptions:
00023     Based on TSOP 1738 IR device, Vcc to 5Volt, Gnd to Gnd, Out has pull-up of 10K
00024     to Vcc and Out has diode (Cathode to Out) connected to pin (p16) (Anode to p16)
00025     and pin (p16) has mode PullUp
00026     
00027     This will allow a "standard" RC5 device to be used to read it transmitted codes.
00028     Still work in progress (in due time) to add newer rc6 devices
00029
