Anybody experience with this topic? Connection? Driver? Library?

Hi Chris,

the current linux-next seems to contain a FB driver for this chip:

Patch (https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/drivers/staging/fbtft/fb_ili9341.c?id=9b78e456a7526755f7c58fb6a249735a4fe0288b)

Wiki (https://github.com/notro/fbtft/wiki)

The connection is done by SPI on the UEXT connector.

Before usage you need to specify the display as a spi node in the devicetree of your board.

Good luck

Stefan

Hi,

I have started some work on packageing fbtft (and fbcon) in openwrt. (Personally
I'm mostly interested in getting MOD-LCD3310 supported.)

This will take a while (think of kernel release schedules for one thing), but
if somebody is using the same approach, maybe we can share the effort ...

HTH,
Harald
