Cannot find correct configs for SAME51G19A

Describe the bug

Test code for the display work fine after altering DC and CS pinout. Nothing appear on display using sample code ex01_ard_basic. Perhaps something to do with the device platform not being detected automatically? In order to get the example ex01_ard_basic to compile I needed to manually #define AVR, perhaps this is the root of my issue..

Device hardware

MCU: SAME51G19A - CANBed M4
Display with link: https://amz.run/50KK Adafruit ILI9341 Generic
GUIslice config selected: ard-adagfx-ili9341-notouch.h Modified CS, DC, and RST pins to match HW

Checklist to try first

Most display/touch issues can be identified by working through the steps in the Configuring GUIslice guide.

Please confirm whether:

Display works correctly with standalone display driver library examples (eg. TFT_eSPI graphicstest, Adafruit graphicstest, etc.) without GUIslice: Yes, Adafruit_ILI9341.h example code name, "graphicstest" works find after changing pinout
Touch works correctly with standalone touch library examples without GUIslice: No touch

Expected behavior

I expect to see the black box on grey background as shown on https://github.com/ImpulseAdventure/GUIslice/wiki/Configure-GUIslice-for-ARM-Cortex, Step 5

Initialization messages

Please copy any startup messages / errors reported to the serial monitor window here. You can enable all error messages by setting DEBUG_ERR 2 in the GUIslice config file.

GUIslice version [0.17.0]: Init display handler [ADA_ILI9341(SPI-HW)] OK No touch handler enabled

Additional info

I needed to add '#define AVR' in order to compile..
