I've been struggling to get my 2.2" ILI9341 TFT LCD Display to work. Despite following various tutorials and trying different wiring setups, all I get is a white screen. Here's what I've done so far:
- Checked and rechecked the wiring multiple times
- Tried using the display without resistors in the wiring
- Used the recommended libraries and code for the ILI9341
Additionally, here's the output I get from the serial monitor when running graphics tests:
18:40:43.313 -> Rectangles (filled) 3107216 18:40:47.338 -> Circles (filled) 465816 18:40:48.085 -> Circles (outline) 541572 18:40:49.126 -> Triangles (outline) 281668 18:40:50.195 -> Triangles (filled) 1339904 18:40:52.636 -> Rounded rects (outline) 243748 18:40:53.679 -> Rounded rects (filled) 3132656 18:40:57.619 -> Done!
The graphics tests seem to run, but the display remains white. I'm using an Arduino Uno with the following pin configuration:
VCC-5V
GND-GND
CS-10
RST-8
DC-9
MOSI-11
SCK-13
MISO-12
also backlight to 5V !
I would appreciate any guidance or suggestions on what might be causing the issue and how to resolve it.
Thank you in advance!
