Split from old (2020), abandoned thread: https://community.st.com/t5/stm32cubemx-mcus/uart-emulation-an4457-is-it-possible-to-use-it-via-cubemx/td-p/310812 for better visibility - and to enable marking a solution...
Hi,
I have the same problem, trying to reverse engineer the AN4457 example for an H7xx MCU using with STM32CubeIDE. Currently my problem is that I need to "#define HAL_UART_EMUL_MODULE_ENABLED " in stm32h7xx_hal_conf.h, but there is not "USER CODE" field, so the define gets overwritten each time I change the IOC file.
I guess the proper approach would be to select the UART_EMUL module in the device configuration tool of the GUI, but I do not know how to make it visible there ...
Did anyone implement this example using an IDE? It would be really helpful for the CubeIDE users.
Thanks!
Solved! Go to Solution.

You could just add it as a Defined Symbol in the Project Properties (Settings) ?
PS:
The above is from right-clicking the Project, and choosing 'Properties'.
You can also get to the Define Symbols setting by right-clicking an individual file, or a folder. I've not tried it myself, but I think that should let you apply it to just an individual file, or just a folder ...
