will this TFT 2.2" lcd work with pi?

Mon Apr 03, 2017 10:20 pm

Hi All,

i've bought a small 2.2" TFT lcd for my pi:

i don't see anything like MISO and MOSI pins from the pic that seller provided, seems that only SD card pins support SPI, is there anyway to hook it up with raspberry pi?

Thanks

I think you're right - looks like it uses a parallel interface for the screen, and SPI is only for the SD card.

I wired it with my pi and modprobe it with custom gpio mappings, when i run con2fmaps 1 1, the lcd showed a white screen with nothing, any suggestions?
