3,5" IPS ILI9488 on Arduino Due with hardware SPI

[PatMan6889]

Hello!

I got an ILI9488 3,5" LCD as IPS version and want to run it on an Arduino Due.

I use this software SPI initialization and it is working fine:

Arduino_DataBus *bus = new Arduino_SWSPI(TFT_DC /* DC */, TFT_CS /* CS */, TFT_SCK /* SCK */, TFT_MOSI /* MOSI */, -1 /* MISO */);

Arduino_GFX *gfx = new Arduino_ILI9488_18bit(bus, TFT_RST /* RST */, 3 /* rotation */, true/* IPS */);

I would like to use hardware SPI but I cannot get it to run. All I see is a blank white screen:
Arduino_DataBus *bus = new Arduino_HWSPI(TFT_DC /* DC */, TFT_CS /* CS */);

Other SPI devices work with the same wiring.
Do you have any idea what is wrong?

Best regards

try lowering the speed

try lowering the speed

I tried with

bus->begin(8000000);
gfx->begin(8000000);

to lower the speed but no success. I also went down to 1 MHz.

then no idea, I don not have Arduino Due in hand so cannot support it
