ESP8266 Community Forum

- Thu Sep 17, 2015 9:24 am #29249 Not sure if this is the right forum, but recently got a generic (eBay) $7 ILI9341 (TFT driver) + XPT2046 (touch driver) module working on the ESP. The code is available on github:

• Ucglib port to ESP8266: https://github.com/spapadim/ucglib (plus this patch: https://gist.github.com/spapadim/a4bc258df47f00831006)
• XPT2046 hardware SPI driver: https://github.com/spapadim/XPT2046

You need to use all available pins (except UART -- but, if you wanted backlight control, you'd have to use one of those as well).

Combine with, eg, ~$3 ESP-12, and you can have a $10 device with graphical touch UI and network. If interested and you try out, please let me know how it went.

If you're using the board manager, both paths (platform.txt and the linker script) are relative to the package's install root, which on Linux is $HOME/.arduino15/packages/esp8266/hardware/esp8266/<version>/ -- should be something similar on other platforms. FWIW, patches are against version 1.6.5-1084-ga39ce29 (staging), but should work on others (or just manually edit the files).

would these from fleabay be compatible?

This one would be cool too, but I don't think it uses same chips
