Nice! This is the first project I've seen with an affordable and apparently good-looking & functional touch screen solution. For various embedded projects I've been looking for a board that runs linuxcnc/HAL, with either on-board IO/Microcontroller/FPGA or the possibility to use a MESA card. A touch-screen would be used for UI. Raspberry Pi. + small, cheap - the processor is slow - barely able to boot a standard debian desktop. - There are some touchscreen hacks but nothing universally used & good. - two SPI channels, one of which (maybe) goes to touch-screen use. ITX-sized x86 + stock standard x68 - 7" HDMI touch-screens exist (e.g. lilliput UK), but expensive (200 eur/gbp/usd). - expensive (board 100eur, processor 100eur, etc.) + PCI or PCI-E for MESA card For now I am slowly working on the x86 solution, mostly because it is tried & tested, but these substantially cheaper ARM alternatives seem to be progressing... Does anyone know what electronics would go between the HDMI-connector of an x86-board, and the 55eur Olinuxino 7" touch-screen? Is it something one could DIY for less than 150eur which is roughly the price-difference to a 7" Lilliput HDMI-interfaced (USB for touch) screen ? Definitely keep us posted on the progress, and latency-numbers if/when you get a xenomai kernel going.
