Hello everybody,

I'm trying to use SPI python module onionSpi (C lib. libonionspi) in order to connect with a tft display. I following the steps in this tutorial https://docs.onion.io/omega2-docs/spi-python-module.html but at device registration spi.checkDevice() an error occured for missing kernel module "Failed to find spi-gpio-custom. Maybe it is a built in module ?" Opkg return that there is no such module in the repo.

opkg install spi-gpio-custom
Unknown package 'spi-gpio-custom'.
Collected errors:

• opkg_install_cmd: Cannot install package spi-gpio-custom.

I also tryed to install spi-gpio-driver but no luck
opkg install spi-gpio-driver
Unknown package 'spi-gpio-driver'.
Collected errors:

• opkg_install_cmd: Cannot install package spi-gpio-driver.

Does this mean that I have to compile spi-gpio-driver from source?

Thank you!

Thanks for your prompt replay and suggestion! I will try the small one https://learn.adafruit.com/adafruit-2-4-tft-touch-screen-featherwing. Also I think this one will work with some additional work

Thanks!

I have exactly same idea for Omega2 and I started development. The problem that I met for now is missing framebuffer kernel module in opkg repo in order to use full functional color display without additional VGA chip. I wondering did you find any module or driver to supporting any kind of color display ?
