Infrared coding is data transmission and household appliances remote control a common communication method, its essence is a pulse width modulation of serial communication. Home appliance remote control
The commonly used infrared coding circuit have μ PD6121G type HT622 type and 7461 type, etc.
Here to the circuit code format to simulate how to use a single chip microcomputer capture interrupt function to realize its decoding. Infrared communication sends department
The main points to send data is converted into certain format pulse, and then drive infrared light tube sent out the data. Receiving part is complete infrared
Line of receiving, amplification, demodulation, reductive into synchronous launch the same format (but high and low potential is just the opposite of the pulse signal). These work usually consists of an organic whole
The head of receiving to complete, the main output TTL compatible level. Finally through the decoding the pulse signal conversion to
