GDPR-2
For everyone running the latest build/version with a box that has a display on the front:
If your display lights up (meaning the DTB is OK), but does not work correctly (e.g. incorrect character order, or weird symbols displayed instead of numbers, etc), I made a small test app that will help me/us figure out how the LCD is connected and mapped internally for your particular box.
See attachment for the app and instructions below:
1. Unzip it into the box (I used the downloads folder)
2. SSH into the box.
3. type in 'bash test_lcd.sh' and then enter.
This will unload the firmware LCD driver and load the test driver+app.
It will run through 2 tests:
1. It will light up all sections of each character, one by one. This will help us pin point which character is assigned to what numeric index. (like which char for index=0, which one for index=1 etc.)
2. It will light up one section in all chars, one by one. This should help us see the bitmap indexes of each char.
*. A video of the box cycling through this test app will be the best help for me to get it working on your display.
After you're done, simply reboot the box to go back to 'normal'.
