Re: 7 inch Screen Calibration

If you plan on using the JackAl system with both USB power and the 3.3V supply, you should but the trace between the VUSB pads on the underside of the board:
This will prevent a conflict between power from the USB port and the 3.3V supply. If you later find you don't need the USB connection to the PC, you can jumper the traces again. I don't think this is your problem, however, but it is a safer way to keep the USB connection between the UCB port and the Teensy.

just looking at the code and the serial.print values,
I'm assuming i should be monitoring the serial monitor to get the values and not on the display.
so that requires the teensy to be connected to the computer and the board fired up with the display.
so when i connect the teensy to the computer with the board powered up, doesn't get recognized, but if i disconnect board from the supply it connects.
does this relate to the 2 pads under the teensy that are connected? and should be separated?
Thanks
still a bit confused..
