in the received message recognized. The total transmission time is constant, because the

duplication of every point of its length negated. If you're not interested, you can ignore this

reliability negated address and command can also expand to 16!

According to the characteristics and the receiving end of the waveform of the NEC coding, this

experiment will divided receiving end’s wave form into four parts: Primer searching code (9ms

And 4.5ms pulse), the address code 16 (including an 8-bit address and 8-bit address is negated),

the command code 16 (package

Including eight command-bit and 8-bit command negated), repeat code (9ms, 2.25ms, 560us

pulse). HIGH segment of the received waveform and low section to be measured using the timer,

based on the measured time to distinguish: a logical "0", a logical "1", cited seek pulse, repetitive

pulses. Boot code and address code as long as the judge is correct pulse can be, without storage,

but the command code must be stored, because each key command codes are different.
