NHD-7.0-800480FT-CSXN-CTP, issues controlling with Teensy 3.6
« on: December 31, 2018, 12:55:26 PM »
Hi.
recently I bought one of these screens, (7", capacitive touch) and have been trying to get any of the test/example sketches to work with it.

I'm using a Teensy 3.6, programmed with the arduino IDE and teensyduino.   The teensy is confirmed working (have used it on other projects, as well as the generic "blink").

I have the teensy/Display wiring as follows:
Teensy--NHD
CS0(dig10)--IDC6
MOSI0(dig11)--IDC5
MISO0(dig12)--IDC4
SCK0(dig13)--IDC3
dig8--IDC8
dig9--IDC7

I have also wired the display to an adjustable power supply (3.3vdc) as follows Teensy is also powered by the same supply.
Pins 1, 17, 18 to 3.3v
Pins 2, 19, 20 to Gnd

Sketch compiles and uploads without error, but I get zero response from the screen.
Any help on what to check?

Thanks
