I'm trying to use a raw TTL display with the raspberry pi but haven't found any documentation on the peripheral, or even to what pins it's broken out.
If you haven't seen it adafruit managed it here: https://www.youtube.com/watch?v=DTuvzxkVaKs
They built on the VGA666 device tree: https://github.com/fenlogic/vga666/blob ... i.dts#L193
Reading the device tree and board schematics gets me...almost there, but i'm not sure how they got things working with out any kind of documentation.
I can resort to switching on the VGA666 device tree and busting out a logic analyzer, but i'm surprised there isn't any thing written down.
