micropython_AS7341: A Python repository from bjones14

Introduction

CircuitPython library for use with the Adafruit AS7341 breakout. NOTE: Due to the size of this library, it may not work on M0 (ex: Trinket M0) and other low memory boards.

Dependencies

This driver depends on:

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-as7341

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

sudo pip3 install adafruit-circuitpython-as7341

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-as7341

Usage Example

from time import sleep
import board
from adafruit_as7341 import AS7341

i2c = board.I2C()  # uses board.SCL and board.SDA
sensor = AS7341(i2c)


def bar_graph(read_value):
    scaled = int(read_value / 1000)
    return "[%5d] " % read_value + (scaled * "*")


while True:

    print("F1 - 415nm/Violet  %s" % bar_graph(sensor.channel_415nm))
    print("F2 - 445nm//Indigo %s" % bar_graph(sensor.channel_445nm))
    print("F3 - 480nm//Blue   %s" % bar_graph(sensor.channel_480nm))
    print("F4 - 515nm//Cyan   %s" % bar_graph(sensor.channel_515nm))
    print("F5 - 555nm/Green   %s" % bar_graph(sensor.channel_555nm))
    print("F6 - 590nm/Yellow  %s" % bar_graph(sensor.channel_590nm))
    print("F7 - 630nm/Orange  %s" % bar_graph(sensor.channel_630nm))
    print("F8 - 680nm/Red     %s" % bar_graph(sensor.channel_680nm))
    print("Clear              %s" % bar_graph(sensor.channel_clear))
    print("Near-IR (NIR)      %s" % bar_graph(sensor.channel_nir))
    print("\n------------------------------------------------")
    sleep(1)
