[Manual] Connection TFT display ILI9341 (custom Dash)

[Modest Polykarpovich]

Hi all. Yesterday I've connected my TFT display (3.2" controller ILI9341 320x240) and Omega2. Look at the photo below.

I don't have Dash board, but I re-compiled firmware with drivers (kernel objects).
If someone else wants to do it, I post here my experience.

Hardware connection

Let's see connection diagram below.

It's item named "LCD TFT 320x240 Graphic Color Touch Display ILI9341 Mega2560 Arduino Compatible" from AliExpress.

Software setup.

1. You must select the next components (via make menuconfig to in-built firmware: kmod-fb kmod-fbtft-support kmod-fbtft-ili9341, dejavu-fonts-ttf-DejaVuSans.

   Then you have to append initial script (filename files/08-fbtft-device) from Omega2 Dash Package repository

2. Or select omega2-dash-base in make menuconfig menu.

3. Or select the board Omega2 Dash in the same menu.

4. Or download and force upgrade firmware (filename omega2dash-vX.X.X-bXXX.bin) via util sysupgrade from repo.onioniot.com. DIDN'T TESTED!

See next useful links about it:

• Omega2 Dash Guide
• Dash на GitHub.
• Omega2 Dash Base Package
• Using fbtft_device on notro/GitHub wiki

This should work assuming your TFT <-> Omega connections are the same as the Dash
