What changes are needed to make this work with the LPC4088 Experiment Base Board and 5in display?

Program as written fails with "Failed to open display: 3" error. Do I need to use EaLcdBoardGPIO as you have done in other Experiment Base Board graphical projects?

Yes, you must use the EaLcdBoardGPIO instead of EaLcdBoard as some of the signals are handled differently on the LPC4088 Experiment Base Board. I suggest starting with e.g. this one:

Import programlpc4088_ebb_gui_globe

Graphical demo for the LPC4088 Experiment Base Board with one of the Display Expansion Kits. This demo shows a number of dots projected on a rotating sphere.

and then adding in the code from main.cpp in app_gfx.

Can you clearly explain me about how to do "app_gfx" in LPC 4088 Experiment Base Board and 4.3 inch display. Thank you in advance
