 Note that this software has it's own small wrapper for the config file, e.g. to have instant access to an LCD object generated on the fly. These are all documented in the [utils.py](utils.py) file! When setting configuration options from your custom code, keep in mind that doing this via the `Config().<ATTR_NAME>` way just means writing the value directly to the file, while getting it goes through the wrapper to make e.g. the pin a machine.Pin object. But you just can't write a pin back into an attribute.
