I did try loading a driver for a commonish chip, ST7789v, and operate under the assumption that it was SPI, but so far nothing but a white screen. I did try cycling through all the pins past pin 7 hoping one of them was the one for MOSI (Driving with a RPi 0)
A lot of those "Close but not quite" SPI displays seemed to share pins like Reset was commonly pin 4 and CS was 5.
I did trace that pin 1 is def BL led + and pin 2 is ground and I'm guessing pin 3 was 3.3v
But so far, nothing but white screen
I tried to peer through the FPC with a bright light looking for a chip, but couldn't find any. Fairly certain it's on that little strip of green PCB but it might be covered by that black goo. The only thing I was able to make out was in that pic with the "T24QV1-S"
I know parallel comes in 8 and 16 bit flavors, so I think there's enough pins for 8 and I could have sworn I saw 24 pin 16 bits listed, but maybe not
