HDMI output over SPI - simply an idea to do this..

[Andreas Thölking]

We connect the Omega2 to an raspberry pi zero via spi and the raspberry pi simply translate this data to the HDMI output. - Is this an good idea???

[Maximilian Gerhardt]

Do you want to send whole framebuffers to the Pi via SPI? That would be a lot of data and FPS would suffer but its possible (and costly). Maybe use a USB GPU like I did?
Or if the display doesn't have to be big just use it directly via SPI.
