Introduction

CircuitPython driver library for AMS TCS3430 / TCS34303 XYZ tri-stimulus color sensor.

Dependencies

This driver depends on:

• Adafruit CircuitPython
• Bus Device
• Register

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.

Purchase one from the Adafruit shop

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-tcs3430

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

sudo pip3 install adafruit-circuitpython-tcs3430

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .env/bin/activate
pip3 install adafruit-circuitpython-tcs3430

Installing to a Connected CircuitPython Device with Circup

Make sure that you have circup installed in your Python environment. Install it with the following command if necessary:

pip3 install circup

With circup installed and your CircuitPython device connected use the following command to install:

circup install adafruit_tcs3430

Or the following command to update an existing version:

circup update

Usage Example

import time

import board

from adafruit_tcs3430 import TCS3430, ALSGain, InterruptPersistence

i2c = board.I2C()
tcs = TCS3430(i2c)

print("TCS3430 Basic Test")
print("TCS3430 found!")

# --- Tweak these settings for your environment ---
tcs.als_gain = ALSGain.GAIN_64X  # 1X, 4X, 16X, 64X, or 128X
tcs.integration_time = 100.0  # 2.78ms to 711ms

# Enable ALS interrupt so we can poll AINT for data ready
tcs.als_interrupt_enabled = True
tcs.interrupt_persistence = InterruptPersistence.EVERY
tcs.clear_als_interrupt()

while True:
    # Wait for new data
    if tcs.als_interrupt:
        x, y, z, ir1 = tcs.channels
        print(f"X: {x}  Y: {y}  Z: {z}  IR1: {ir1}")
        tcs.clear_als_interrupt()

    time.sleep(1.0)
