    • Screen will not turn on when I add or delete text

      Hello,
      I have been experiencing a problem for the past few days that is driving me crazy. I inherited a project from a coworker which involves a Renesas microcontroller with an 18-bit display. I managed to configure the project, and everything seemed to be working correctly. I made several modifications using AppWizard, and everything appeared to be fine until I attempted to add or remove new text. When I do this, the screen no longer initializes, and I believe the issue might be with the initGUI function. I am not sure what else to try. I am attaching the changes that are causing the screen not to turn on. Could someone please assist me?

    • Hi,

      I can imagine that the AppWizard version doesn't match the emWin version in your hardware project.

      Are you using the same AppWizard version as your colleague?

      If you are using a newer tool you have to make sure you are also using the matching emWin libraries on your hardware.

      Here you will find out how to check if the emWin and AppWizard version match each other.

      segger.com/doc/UM03003_AppWizard.html#AppWizard_version

      You can get access to the correct libraries by clicking "Export libraries" in the "File" menu (seen on the screenshot).

      Currently the AppWizard comes only with GCC libraries for Cortex-M4/M7 and CCRX V2 and V3 libraries.

      Does this solve the issue?

      Regards,
      Sven
