Hello,

I have a problem with running a  TFT. My LCD chip is SSD1289 . I have communication between the board ( stm32f407 - discovery ) and the LCD but there isn't a text on the screen. I attach my code.

    The number of people with your configurations is approaching zero, and to wade through your code lacking much context, is a big ask. I certainly don't have time to waste on it.

    Suggest you start by reviewing your hardware and connectivity, and try writing and reading back the SSD1289 register(s), and confirm things work at that level. And that you can access the frame buffer. Review the panel/chip documentation.

    The peripheral banks have 16 pins, not 8, and I'm really not sure how the free/available pins relate to your implementation.

    I use this code to run the TFT on other chip c8051f021. That why I decide to rewrite it and use for stm32f4.

    Thanks for answer.
