3、 Usage
The usage of this module is very simple. The following will explain it in terms of electronic and non electronic majors:
Electronic major:
Simply utilize the serial communication knowledge of the microcontroller to send specified instructions through the serial port for control module transmission; Perform infrared encoding operations through serial port reception to obtain remote control encoding information.
Decoding: No instructions need to be sent during decoding, just pick up the remote control and align it with the receiving head of the module, and press it. At this time, the serial port of the module will output the infrared code.
Encoding (transmission): When encoding, instructions need to be sent according to a certain format. By sending 5 bytes of instructions through the computer or microcontroller serial port, the corresponding encoded infrared signal can be restored.
By utilizing the infrared transceiver function, we can perform infrared data transmission and control. Purchasing 2 sets can complete the transceiver operation.
Non electronic majors:
If customers do not understand the knowledge of microcontrollers, they can use our store's USB to TTL combined with a computer to control other devices. After connecting the circuit, the computer's upper computer software can easily send and receive instructions, achieving encoding and decoding functions.
Instructions for operation:
