eGUI on Freedom K20N50 with Novatek NT7534

Question asked by Scott Allred on Sep 9, 2013

Hello community!

 

I'm trying to get a Newhaven 124x64 graphics display to work (over SPI), which has a Novatak NT7534 display driver in it.

 

I've created my own LLD for the NT7534, which doesn't do much more than just initialize the display.  I also wrote my own HW LLD for SPI on Kinetis, because I used Processor Expert to instantiate the SPI module.

 

My main screen just instantiates 2 labels.  I've attached the files for my SPI driver, my NT7534 driver, and my main screen.

 

The SPI port writes out the initialization, but nothing is drawn on the screen, and there isn't any SPI activity after the initial setup.  Might anyone have any suggestions on where to go from here?  I greatly appreciate it!!!
