I added an LED module and controlled the on and off of the LED through MY_CUSTOM_COMMAND0 and MY_CUSTOM_COMMAND1. When I input MY_CUSTOM_COMMAND0, it works fine, but when I input MY_CUSTOM_COMMAND1, an error occurs and the MCU shuts down.

FWIW,
Your code defines and controls things in the wrong way, so you get an error.
Specifically, you set up max duration (which is used for heaters mostly) and then use API for gpio toggle.
If you take a peek at led module, you will notice, that there are: mcu_pin.setup_max_duration(0.)

In general, it is better to use existing code and existing modules or at least read them to get an idea how things are done.

Hope it helps.

Thank you. I’ll try to use the output pin to achieve the function I need. This seems to be more convenient.
