Raspbian based Trueview5725 i2c controller

Preliminary scripts for testing new custom settings on Trueview5725 based video processors. GBS8200, GBS8220, and maybe others in the future (HD Box Pro)

============= INSTALL GUIDE

The install script is designed to be used with a fresh vanilla Raspbian install. to install or update run the following command:

curl https://raw.githubusercontent.com/dooklink/gbs-control/master/install-gbs-control.sh | bash

or for the development version (not guaranteed to be working)

curl https://raw.githubusercontent.com/dooklink/gbs-control/develop/install-gbs-control.sh | bash

=============== Usage

Raspberry pi will auto boot into the config menu displayed via the Green RCA Luma input on the GBS board from RPi composite output. The Raspberry Pi must be connected to the I2C lines (SDA, SCL and GND), of the target board. Also, the P8 jumper on the GBS82xx boards must be shorted to ensure RPi can be I2C master without interference. Global keyboard hotkeys are preconfigured to switch between the Config Menu and the RGB Video Source. Other tweaks can be make with the keyboard hotkeys.
