  • [SOLVED] Hard Fault While Trying to Execute GUI_CURSOR_Show()

    Hi,

    I am using emWin v5.26/v5.28 with RA8875 and STM32F2. The display works fine.

    However, when I add the function GUI_CURSOR_Show() right after GUI_Init(), the program just halts.

    Please assist. Thank you.

    Edit #1:
    Could it be the GUIDRV_FLEXCOLOR_F66721 requests touch panel data directly from RA8875? (in which case I need to initialize the RA8875 properly first?)
    ---
    Edit #2:
    Forgot to implement pfReadM16_A0(), now working properly.
