Once started, only core 1 is performing the render. Core 0 is free to run whatever code is populating the frame buffer.Thanks, appreciated, and I had looked at that as I consider VGA more useful than HDMI. Not having understood 'scanvideo' and needing both cores with a render loop is what gave me hesitation but maybe I shouldn't worry about that, should just do it and go from there.Not quite what you want, but I did 640x480x4bit VGA frame buffer for the RP2040 some time back. Code can be found on GitHub.
