IR Remote and IR Receiver for KODI (Arduino sketch)

userHead LNC-SPN 2019-03-08 06:44:21 9533 Views0 Replies

Hi Lattepanders! If you want to control Kodi with an IR remote this is for you. 
Works on all versions of LattePanda.

SOFTWARE

KODI - Open Source Home Theater Software:
https://kodi.tv/download

To run Kodi when Windows starts: 
Put a Kodi.exe shortcut in the startup folder (Win + R | shell:startup)

To run Kodi when Windows starts and bypass the explorer shell:
Run the Group Policy Editor (gpedit.msc), then navigate to:
User Configuration -> Administrative Templates -> System and then select “Custom User Interface” 

Enable it and enter the entire path of Kodi.exe
(ie: C:\Program Files (x86)\Kodi\Kodi.exe)

*To get back into Windows from Kodi. Exit Kodi and then start the task manager (Ctrl:Alt:Del) and run task ‘explorer.exe’

Arduino IDE sketch & Libraries (IRremote & Keyboard):
Download from Google Drive: https://drive.google.com/file/d/1WGziGu ... lkzps/view
 

Extract the two libraries folders (IRreceiver, Keyboard) into "C:\Program Files (x86)\Arduino\libraries"Extract the IR_Receiver_for_KODI folder into "Documents\Arduino"Open "IR_Receiver_for_KODI.ino" with the Arduino IDEUpload the skecth (make sure the Arduino Leonardo board and their COM port is selected in Tools)

Sketch Code:

*Note: The remote IR codes are from the "Gravity: IR Kit for Arduino" remote https://www.dfrobot.com/product-366.html
If you are using another remote just monitor the serial output and press the remote buttons. Then change the HEXA codes in the ( REMOTE IR CODES ) section.
