RaspberryPi control interface that acts as i2c master to control the Trueview5725 in cheap scaler boards and allows running custom modes.
What does this allow me to do?
This project allows you to control the Trueview5725 directly on the GBS8200, GBS8220, and similar boards.
What does this mean for me (the end user)?
This allows you to have a different OSD for your scaler board and it allows more freedom over the modes it runs.
What do I need to make this work?
You will need:
- some Linux experience
- some soldering skills and basic soldering tools
- some wiring
- a scart female connector
- a 75ohm resistor
- a 470ohm resistor
- a raspberry pi
- a board that features a Trueview5725 chip
- a lm1881n (optional)
- two 100nf capacitors (optional)
Full instructions are present on BUILDINGHW.md
How do I install the Raspberry Pi software?
- DD a Raspberry Pi OS Lite image to your SD Card and do the first time setup (you are now required to make your own user and choose your own password)
- Connect the Pi to the internet
- run
curl https://raw.githubusercontent.com/paranoidnela/gbs-control/master/install-gbs-control.sh | bash(I highly reccomend to take a look at the script before blindly executing it, it should be fine rerunning the command if you want to update the Pi)
Hotkeys
Here is a list of hotkeys, you can change them on the thd directory.
- F1: Toggle OSD
- F2: Output Mode
- F5: Quick Save
- F7: Quick Load
- Grave or Tilde + (1, 2, 3, 4) Change the OSD output mode (I would stick to 2 and 4)
- CTRL + (1, 2, 3, 4, 5, 6, 7, 8) +Vertical Size(If Enabled), -Vertical Size(If Enabled), -Horizontal Size, +Horizontal Size, Picture Up, Picture Down, Picture Left, Picture Right.
