These TFTs are well known, serial interface.
So, I wanted to get a response if anyone has ever succeeded to read back from either one of these 1.44" or 1.8" displays.
SPI = Simple, 3 wire, full duplex, synchronous serial data transfer
I have the 1.44" TFT working, but as said, can't read back.
The parallelel mode has the R/W line I was talking about. Also, the parallel ram concept would depend on you knowing the memory map of the display.
