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.

interesting, thanks!
is the speed a limitation from the vocore or the lcd that u used?
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.
