CircuitPython library for use with the Adafruit AS7341 breakout
Project description
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-as7341To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-as7341To 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-as7341Usage 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))
