    @WMXZ: Congratulations on getting uSD read resolved! I took the update text back to the prior linked post. Like Kurt I found the USB_Host Serial to see a Connected Teensy - one of my Serial Debug T_3.1's - but would...

    Crazy it should act that way. I should have sent it back for being slow - though it may be different with TyComm only didn't re-swap the 3 Teensy setup back to that and look at start timing - was going to do that when...

    Paul has this qvgatest_touch that fits the ILI9341 - hopefully the pinout matches the new boards like Paul linked? The Ebay unit Kurt linked is setup for rPi header to SPI - FrankB's style board would be nice there!...
