The BeagleBone HDMI output will work fine with either the CRAMPS or the BeBoPr++, and you can use an inexpensive adapter to connect to a DVI monitor if that's more convenient. Most of the Machinekit/LinuxCNC interfaces are geared towards 800x600 or higher display resolutions. When I connected a low-resolution 7" LCD (800x480), there wasn't enough vertical resolution to see everything on the display (you really do need about 600 vertical lines for the Axis UI). There are some new Qt based user interfaces that are just now coming out, but they probably won't run well natively on the BeagleBone until the SGX GPU drivers are made to work with the Xenomai patches in a 3.14 kernel (work is in progress, but I can't advise you to assume it will all be working happily together soon). If you're willing to use an Android tablet or other remote system as a display you might want to look into the new interfaces. I have several 1280x1024 DVI monitors that work really well with the BBB HDMI output (using a physical adapter), and 1024x768 would also work well. If you use an HDMI monitor, 720P is pretty reliable, but 1080p needs to run at a 24-30 Hz frame rate (due to the BBB pixel clock limits) and not all HDMI monitors will support that. -- Charles Steinkuehler [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
