[Emc-users] A GPU for SBCs and SOCs Re: about to give up on the pi's

I'd like to see someone buy the Rendition Verite intellectual property from Micron, then make the design open, with a very small royalty fee per chip. A few cents each, at least until the cost to buy it is recovered. The Verite 2200 could be given a major die shrink by transitioning it to the la

Gentlemen, I am running Wheezy with an ELO touchscreen, The software installation recognized the touchscreen and loaded the ELO calibration app. I ran that (touching the screen in several places) and the app gave me numbers to put in a configuration file and the address of the configuration file.

Re: [Emc-users] about to give up on the pi's

From my understanding, a straight Debian armhf distro install will run on the rPi 2 and rPi 3. It should also provide performance improvements over Raspbian.
