Thanks,
For the most part I think I have the display running fast enough for most things I want to do. My main reason for working with the Edison is because Trossen Robotics with Intel and others have stated that they will be using one in their new humanoid project, which I am interested in. But they will be shipping it with their own adapter board, so I will probably need to adapt. Would still like to learn more about how spidev works here and see if there are enhancements we can do in order to speed things up. Maybe there are other ways to try to speed it up, like can you do writes to the device versus the IOCTL? I am also not a heavy linux guy, but I am just stumbling along.
FYI - yesterday my Galileo V2 arrived. was just curious about them. My Arduino IDE version of the driver appears to run on it, but even slower. Again I want to understand more, like different ways to drive the IO pins faster pinMode(9, OUTPUT_FAST) vs ... Also wondering if the faster methods also work on Edison? ... Lots to learn.
The Arietta G25 looks nice. Mostly recently I have been playing around with the Teensy 3.1 boards, which are a nice Arm Cortex M4 that I normally run at 96mhz. It runs completely using the Arduino 1.0.6 IDE (own hardware branch) and he has all most all Arduino libraries ported over to work with the hardware... As I have already mentioned his ILI9341_t3 library is an order of magnitude faster..
