PaperTTY not working with 7in5 V2 screen.

[damavrom]

I try to run PaperTTY on a Raspberry Pi Zero W, with a waveshare 7in5 V2 screen. It doesn't work. It gets stuck at the wait_until_idle function.

I took a good look at the code and I realized that the PaperTTY drivers are actually for the 7in5b V2 screen, and it seems like they are not compatible with the 7in5 V2.
