I'm trying to make a dumb terminal using a PS/2 keyboard, basic microcontroller, and small display. Currently I'm working with a Teensy 3.2 and the Adafruit 3.5" TFT 320x480 display with HX8357D. I'm using PlatformIO in Code - OSS, building the project for the Arduino framework.
Currently have the keyboard working, and incoming text is displaying nicely except that I don't know how to make it scroll vertically (unless I want to wait a few seconds every refresh). I'm using SPI to drive the display now, but I'm not opposed to using the 8-bit interface for speed.
I've spent a lot of time searching the net and looking at Adafruit's documentation and some header files, but I've not made any progress on this for weeks. It's so easy to get this running and use functionality shown in examples, but I feel like as soon as I need to step outside what has been prepped, I drop straight off into the deep end. I'm happy to do the research, but I just need some direction because I'm spinning my wheels right now, wasting a lot of time.
Much thanks in advance for any help!
