RPi, HDMI or SPI Display Without Desktop Environment

Post by peterhouse »

Are there libraries allowing for the use of either HDMI or the SPI based displays without having the entire desktop environment running?

I'm using RPi for embedded stuff and would just like to display a bar graph or something simple on the HDMI without desktop. For now I am limited to ASCII characters using the HDMI as a terminal.

Any ideas appreciated.

We recommend pygame for doing custom UI's. There are some tutorials here:

Thank you, that link was very helpful. Do you have any link to anything using c instead of python?
