Good point. Hadn't thought about that. I'll take a look and see if it has anything that might help. > Your progress is very impressive, my project stalled - I must get back to it. The other option I've been thinking about since late yesterday is to create a variant of devdraw (or add hooks into the existing devdraw) that allows it to shoot off a request to another device for every screen update. My ideal for this scenario is to have a single kernel image that will simultaneously display on both the HDMI port and the SPI display. Then add some bits to boot.rc so that at boot-time, the user can indicate whether they've got the SPI display installed and whether to set the geometry and fonts accordingly. Some of that may end up being a potential project for students in the class to do :) BLS
