I’ve searched a lot, but to no avail. I’ve been trying to use the Adafruit HX8357 TFT LCD display for some time now and I’m out of ideas. Nothing seems to work - the display powers up to a dead, white screen, and then nothing happens.
Here’s some specifics:
I’m using the SPI side of the display. I know that the display and solders are good, because the display works fine when used with my Arduino Uno.
I am running at 5V, sometimes 4.8-ish. I keep a 1000uF 16V capacitor in my breadboard power bus as a filter.
I’m using the Adafruit_HX8357 and Adafruit_mfGFX libraries, and I’m attempting to run the GraphicsTest.ino example file included in the HX8357 library.
My Connections are as follows:
CORE —> DISPLAY
A7 —> D/C
A6 —> CS
A5 —> MOSI
A4 —> MISO
A3 —> CLK
I’m really confused. I’ve used the ILI9341 display with no problem, but the project requires a larger display. I thought for sure with an SPI interface and a web IDE library that this was a perfect choice, but now I’m starting to second guess myself.
Hopefully I’m doing something incredibly obviously wrong that I’m not aware of, but you are!
