TFT Display Showing White Screen Issue

[mercy-joyce]

Hi Guys,
I connected my 1.8 TFT SPI 128x160 display to an ESP8266, and installed the required libraries. then i uploaded a graphics test code from the example menu in the IDE provided by Adafruit. The code uploaded successfully, but all I get is a white screen and nothing else.

I have been trying to troubleshoot this issue for the past 3 days with no luck. Can anyone help me figure out what's wrong and how to fix?

Display part number ? Possibly post the schematic of the whole system/interface
to LCD.

Does display have any power up sequencing constraints ?


Regards, Dana.

The ESP8266 is a 3.3 V device. What about your TFT? If it is a 5 V device, then you may have interface issues.

Have you ensured the code matches the display? Not all TFTs are made equal. Other TFTs will require different code.

@Harald Kapp,
Thank you so much for taking the time to help. White Screen

I had the same white screen issue, and it was caused by incorrect wiring and pin setup. Double-checking the connections, especially SCK, SDA, CS, DC, and RESET, and matching them with the code fixed it for me. Also, make sure you're using the right display driver.
