SD + SPI LCD on vocore 2?

Tue Jun 05, 2018 4:08 pm

hello,
i would like to use this board for a badge project.
my plan is to connect a µSD and a 2.8" SPI display (ILI9341).
i would like to use the fbtft driver, i'm curious if that will work, did someone something like this before?

greetingsa

Please check http://vonger.cn/?p=8216, there are five blog about use SPI screen.
If use fbtft, you will need to hack the kernel a little. :) good luck.

if its the vocore, it will be useless for my application.... :(

it is spi screen...vocore spi max speed is at least 10Mbps, but normally screen with spi interface only support 2Mbps at most.
Do you check my new invention :p ==> vocore2 screen(http://vocore.io/screen.html)? it is go over USB port, speed is no problem, up to 25fps 800x480 at 24bit true color.
