Stm32cube - how to drop default "stm32YYxx_hal_conf_template.h"

vit · October 20, 2021, 12:59pm

On build, ststm32 platform copies stm32YYxx_hal_conf_template.h to stm32YYxx_hal_conf.h.

That works, but only until you need to use custom stm32YYxx_hal_conf.h, generated by stm32cubeMX. For example, if you wish to use HAL callbacks instead of global weak functions.

How can i ignore/drop default stm32YYxx_hal_conf.h? (extra python script would be ok too)

As written in the builder script

          if board.get("build.stm32cube.custom_config_header", "no") == "yes":
              if os.path.isfile(conf_h_path):
                  os.remove(conf_h_path)
          else:
              if os.path.isfile(conf_h_path):
                  return
          
              if not os.path.isfile(template_h_path):
                  sys.stderr.write(
                      "Error: Cannot find peripheral template file to configure framework!\n"
                  )
                  env.Exit(1)
          
              shutil.copy(template_h_path, conf_h_path)

just use

board_build.stm32cube.custom_config_header = yes

in the platformio.ini to ignore PlatformIO’s built-in config file.
