To use this code, only custom.py needs to be modified. This code uses device model MCU_board as an example, that is, the IDFs/ODFs are

def odf():
    return [  # ('odf_name', (param_strings in tuple))
      ('D2-O', ('int', )),
      ('D3-O', ('int', )),
      ('D4-O', ('int', )),
      ('D5Pwm-O', ('int', )),
      ('D6Pwm-O', ('int', )),
      ('D7-O', ('int', )),
      ('D8-O', ('int', )),
      ('D9Pwm-O', ('int', )),
    ]

def idf():

    return [  # ('idf_name', (params in tuple))
      (('A0-I', ('int', )),
      ('A1-I', ('int', )),
      ('A2-I', ('int', )),
      ('A3-I', ('int', )),
      ('A4-I', ('int', )),
      ('A5-I', ('int', )),
