Although most likely touch screens are more common in embedded systems, it's a good example. A lot of touchscreens should work via evdev too. Regarding the logo size: Also an RTEMS logo is a nice idea, maybe something smaller would be better to avoid that big file in the repo? Depending on how you generated the image: Maybe some run length encoding could reduce the size too (for example GIMP offers an option for that when exporting images to C sources). > > Finally, please have a look at this very short video that shows the > example application running.
