In order to enable it, you must: In order to enable it, you must:
- Install Circuitpython version > 7.2, - Install Circuitpython version > 7.2,
- add the `adafruit_pioasm.mpy` library to the lib or root folder of the boards, - pass `use_pio=True` into the `Split()` constructor.
- and pass `use_pio=True` into the `Split()` constructor.
The file is available [on the library release page](https://github.com/adafruit/Adafruit_CircuitPython_PIOASM/releases). From the `adafruit-circuitpython-pioasm-x.y-mpy-0.x.y.zip`, copy the `lib` folder (or its content) to the root of your circuitpython drives. Make sure to get the zip corresponding to your circuitpython version as the mpy format can evolve!
