2.8 inch TFT Touch Shield v2.0(Seeed) not working! Please answer me.
I'm going to connect the nucleo-f401re board with the LCD specified in the title. It used a jumper wire to connect the LCD to the board. Below is the code I used, but when I debugged it on the board, the LCD only had a white screen, but the contents of the code did not appear. I tried other examples, but only the same white screen appeared. Does anyone know how to solve this problem? Thank you for your reply in advance.
If you need any other information, let me know.
When debugging to the source on the top page, only a white screen appears.

The LCD is white means it is powered, but the first line in main loop will set the background to black. There are some troubleshootings I think you can keep debugging. 1. Re-confirm the pins are connected correctly. 2. Use LA to monitor the SPI and TFT_CS signal and check if it's correct. 3. Check if those code lines in main loop are really executed.
