lgtvcontroller's Introduction

LG TV Serial Controller

This is a small program written in plain C for Linux to control my LG TV from the command line. It has been tested under Ubuntu 16.04 Xenial Xerus only.

Compiling

Run make in the folder. No really, that's it.

Executing

Run ./lgtv --device=<device> [OPTIONS] [COMMAND]. If you do not get any output from this command, it means no TV is connected to the selected serial port. If a compatible TV is connected, you should see a X 01 NGSSx reply, where SS is the Set ID (in Hexadecimal) of your television

Options

Short Option	Long Option	Argument	Description
-d	--device	File Device	Selects the file device used to communicate with the TV
-e	--echo	None	Echoes the data sent to your TV in the terminal. This can help you quickly see the commands sent to your TV
-h	--help	None	Shows an help screen for the appliation
-s	--setid	Set ID	Sets the Set ID of the TV with which you want to communicate. If this is not set it defaults to 0, which is the all-call Set ID
