andrewcrussell 0:3110d82c59ff 2 // The Philips RC5 coce consists of 14 bits delivered in bi-phase Manchester encoding from
andrewcrussell 0:3110d82c59ff 3 // an IR LED on the remote. This is picked up by a detector (e.g. a Vishay TSOP3741) which
andrewcrussell 0:3110d82c59ff 4 // outputs the demodulated bit stream as follows:-
andrewcrussell 0:3110d82c59ff 5 // First 2 bits are start bits - allow the detector AGC to stabilize and trigger decoding process
andrewcrussell 0:3110d82c59ff 6 // Third bit is the toggle bit - it remains at the same logic level as long as a key is depressed
andrewcrussell 0:3110d82c59ff 7 // and will change to the alternate state when the key is un/re-depressed or when a different
andrewcrussell 0:3110d82c59ff 8 // key is depressed
andrewcrussell 0:3110d82c59ff 9 // Bits 4~8 are the address bits and determine which piece of equipment is being controlled
andrewcrussell 0:3110d82c59ff 10 // Bits 9~14 are the command bits
andrewcrussell 0:3110d82c59ff 11 // As long as a key is depressed, the 14 bits will be sent by the remote controller in sequential
andrewcrussell 0:3110d82c59ff 12 // blocks with a 120ms delay between subsequent block transmissions
