Third, the use

How to use this module is very simple, the following electronic and non-electronic professional conduct professional commentary:

Electronic Specialty:

    Only need to use the single-chip serial communication of knowledge, sending commands through the serial control module specified emission; infrared encoding operation through the serial receive mode, remote access to the encoded information.

      Decoding: decoding do not need to send any commands, just pick up the remote control receiver alignment module is pressed, then the serial port module outputs the infrared codes.

     Coding (transmitter): Need to send commands based on certain format encoding, serial send 5 byte instruction via computer or microcontroller, it can be coded infrared signal corresponding reduction out.

     Take advantage of this infrared transceiver functions, we can do an infrared data transmission and control, purchase two sets to complete the operation of the transceiver.

Non-electronic specialty:

If the customer does not know how to shop SCM knowledge can be used in conjunction computer's USB to TTL control other devices connected to the circuit after a good computer PC software can send and receive simple commands to achieve encoding and decoding functions.
