These files all use decorators (@asm_thumb, @asm_pio) that add names to the function scope, that the linter cannot see. It's useful to clear them in the file not in pyproject.toml as example code will be copied and adapted elsewhere, and those developers may also use Ruff (we hope!)

# Example using PIO to turn on an LED via an explicit exec.

|
# Note: this does not work on Pico W because it uses Pin(25) for LED output.
|

|
|
# Demonstrates:
|
|
# - using set_init and set_base
|
|
# - using StateMachine.exec
