Introduction

Simple assembler to convert pioasm to bytes

Dependencies

This driver depends on:

• Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-pioasm

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-pioasm

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-pioasm

Usage Example

import time
import rp2pio
import board
import adafruit_pioasm

squarewave = """
.program squarewave
    set pins 1 [1]  ; Drive pin high and then delay for one cycle
    set pins 0      ; Drive pin low
"""

assembled = adafruit_pioasm.assemble(squarewave)

sm = rp2pio.StateMachine(
    assembled,
    frequency=2000,
    init=adafruit_pioasm.assemble("set pindirs 1"),
    first_set_pin=board.LED,
)
print("real frequency", sm.frequency)

time.sleep(120)
