- jrockway 5y agoYou don't need to go through all the steps involving HDMI. Linux can create framebuffers on I2C/SPI displays like this. Many years ago, I connected two to a Beaglebone and it ran Emacs just fine. Much device tree hacking is involved, though, unfortunately.
- makach 5y agoyes, yes, this is exactly what I did. But connecting it to an HDMI port is infinitely much more cooler!
