Subject: Issue with Displaying Speedometer Values on STM32H747XIH6 Board
Dear ST Community,
I am currently working on a project involving the STM32H747XIH6 DISCO board, using TouchGFX to create a speedometer display. I am facing difficulties where the speedometer values are not being displayed on the screen. Additionally, I am encountering some errors during the build and execution process.
Project Setup:
- Board: STM32H747XIH6
- IDE: STM32CubeIDE with TouchGFX integration
- Peripherals: FDCAN for receiving data (speed values)
- Middleware: FreeRTOS and TouchGFX
Problems Encountered:
- The speedometer values are not updating on the display, despite the data being received via FDCAN.
- During the build process, I am receiving the following errors:
- Undefined reference to __sf_fake_stdin, __sf_fake_stdout, and __sf_fake_stderr in FreeRTOS.
- Undefined reference to HAL_FDCAN_Init.
Actions Taken:
- Verified the initialization of FDCAN in both STM32CubeMX and in the code.
- Checked that the necessary HAL drivers are included and compiled.
- Ensured that the FreeRTOS configuration supports standard input/output, as indicated by the errors.
- Cleaned and rebuilt the project, but the issues persist.
I would greatly appreciate any guidance or suggestions to resolve these issues. I am particularly interested in:
- Resolving the linker errors mentioned above.
- Ensuring that the FDCAN data correctly updates the speedometer widget in TouchGFX.
Best regards.
