ILI9488 with Arduino UNO R3

Open LimpidCrypto opened this issue 9 months ago • 7 comments

I'm new to programming with an Arduino. I'm using a Arduino UNO R3 and want to connect a ILI9488 touch screen to it. Here is how I wired it:

  • VCC: 5V
  • GND: GND
  • CS: 9
  • RESET: 7
  • D/C: 8
  • SDI: 11
  • SCK: 13
  • LED: 5V
  • SDO(MISO): 12 I just want to fill the screen blue for now. I use the same wiring in the Wokwi Simulator with a ILI9341 and it works fine. But with the ILI9488 I only the the nearly white screen with only these two stripes in the middle of the screen: image

Here is my very simple code:

Arduino_DataBus *bus = create_default_Arduino_DataBus();
Arduino_ILI9488 *gfx = new Arduino_ILI9488(bus, DF_GFX_RST, 0 /* rotation */, false /* IPS */);
gfx->begin();
gfx->fillScreen(RGB565_BLUE);

If it helps here is also the back of the screen: image

If you need anything to be able to help me better, please tell me what you need. Thank you in advance.
