    The issue about QSPI communication with TFT

    Hello, everyone.

    I have tried to work TFT lcd on TC237 app-kit since 2 weeks ago.
    I have used the demo code for TC237 app-kit which is provided from infineon.
    It has worked well. but I only wanna extract the code for operating TFT because of My project.
    So, I have tried to extract TFT function codes from the demo files.

    However, My TFT has displayed continuous thin black lines like below.
    I copied and pasted this exact same codes on new project for TFT test.
    I think it has QSPI communication problems by unknown errors. but I have exactly copied the TFT code work-well .

    Please give me your opinion about this problem.
    How can I solve this problem?

    IDE used for TFT Lcd ?

    Hi
    Can you please tell me which IDE you have used for initializing TFT LCD?
    I am using Aurix IDE, but unable to lit my LCD. I don't have any sample code.
    My hardware is TC387QP.

    If you have any sample code for that for Aurix IDE, can you please share it with me?

    Thanks in advance.
