When I change the example project ColorFormats ScreenSize from 480, 272 to 320, 240 and build and upload it, I get a blank screen. When I change the ScreenSize back to 480, 272 the screen is displayed again, albeit in 320, 240 resolution. I tried changing the ScreenSize in a newly created STM32F746 template project to 320, 240 and get I the same thing, blank screen. And I have tried keeping the ScreenSize at 480, 272 in a template project and keep the bounds of the rectangle to 320, 240. This doesn't work either.
Here are the 24 bit timings of the Newhaven display;
RGB_DISPLAY_RESOLUTION_QVGA
Values specific to QVGA LCD display
DispWidth = 320;
DispHeight = 240;
DispHCycle = 408;
DispHOffset = 70;
DispHSync0 = 0;
DispHSync1 = 10;
DispVCycle = 263;
DispVOffset = 13;
DispVSync0 = 0;
DispVSync1 = 2;
DispPCLK = 8;
DispSwizzle = 2;
DispPCLKPol = 0;
DispCSpread = 1;
DispDither = 1;
Any help would be appreciated.
