How to set IO port remapping in STM32F103 series CUBE? What I want is to map tiM3_CH2 from PA7 to PB5. Anyone who can help is greatly appreciated.

Click the corresponding mappable IO port directly on CUBE
This is the default TIM3_CH2
If you want to map to PB5, just click PB5 and select TIM3_CH2.
that's it. . .

I now want to map SPI1 to the corresponding pin of SPI3.
Because part of the program has been written, I don't want to use CUBE_MX to update the project again.
If you want to know what operations are required for remapping?
Now a new project is remapped and SPI1 is remapped, and there are more __HAL_AFIO_REMAP_SPI1_ENABLE() functions in the spi.c file. But I don’t know what else needs to be changed elsewhere.

You can create another project to generate this reprint, and then copy a part of the relevant code from another project.
