    My GD2 library didn't have a GD.w or GD.h value, so I hardcoded 480 and 272 in respectively and got it to run.

    Hey, this was the problem for me, too! I reported this as an issue with Autodesk.
    It is strange, tho. I didn't have any problem with regular Arduino Uno clone boards, just the Teensy.

    Their connector only has a pin for DC-5V, but they are using an XC6209 to regulate it down to 3.3V for everything that needs that, while still having 5V to power the LCD backlight. I grabbed 5V from...
  4. Need help with FT800 using Gameduino 2 libraries on Teensy 3.6

    I'm having some trouble getting the Haoyu FT800 based displays to work with the Teensy 3.6. I'm using the Gameduino 2 libraries with pretty much the same pin connections as they set up for the...

    As far as tearing goes, perhaps the Get_Scanline commane (0x45) could be polled to detect display update synchronization, and then all pixels sent during the blanking period, or just after the...
  6. Changed F_BUS in kinetis.h to improve framerate, thanks Frank B!

    Ah, thanks for the tip! I had tried changing SPICLOCK in the ILI9341_t3.cpp, but since the SPI is set to max at 1/2 F_BUS, it didn't really do anything. I didn't realize F_BUS could be changed.

    Hey, I was just testing some code on the Teensy 3.6, and I ran some benchmarking.

    I've seen all that (and made one of my own), but I can't really ask a manufacturer to bend pin headers and such. I was hoping that it was designed around some particular, off-the-shelf connection...
  9. Teensy 3.2 bottom pads: Is there some connector for that?

    I was wondering if the pads on the bottom of the Teensy 3.2 were designed to fit any particular type of commercially available connector?
    While I know of various homebrew solutions, I will...

    I'm actually writing exactly this right now. What I did was this.
    1. If the pot has changed, store the value and mark as "Dirty"
    2. In the main loop, check to see if the output buffer is clear.

    Faced with the choice between adding lots of extra support logic, or finding some way to access the tiny pads on the back of the Teensy 3.1/3.2, I finally decided to do something about it.

    Hi!
    I just got in a bunch of the XPT2046 touchscreens.
    Has anybody else noticed a LOT of position jitter even when the stylus is completely still?
    Also, I am noticing a sort of "approach time"...
