Project description

Introduction

CircuitPython library for the Maxim DS3502 I2C Potentiometer

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-ds3502

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

sudo pip3 install adafruit-circuitpython-ds3502

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-ds3502

Usage Example

from time import sleep
import board
import adafruit_ds3502
from analogio import AnalogIn

####### NOTE ################
# this example will not work with Blinka/rasberry Pi due to the lack of analog pins.
# Blinka and Raspberry Pi users should run the "ds3502_blinka_simpletest.py" example

i2c = board.I2C()
ds3502 = adafruit_ds3502.DS3502(i2c)
wiper_output = AnalogIn(board.A0)

while True:

    ds3502.wiper = 127
    print("Wiper set to %d"%ds3502.wiper)
    voltage = wiper_output.value
    voltage *= 3.3
    voltage /= 65535
    print("Wiper voltage: %.2f"%voltage)
    print("")
    sleep(1.0)

    ds3502.wiper = 0
    print("Wiper set to %d"%ds3502.wiper)
    voltage = wiper_output.value
    voltage *= 3.3
    voltage /= 65535
    print("Wiper voltage: %.2f"%voltage)
    print("")
    sleep(1.0)

    ds3502.wiper = 63
    print("Wiper set to %d"%ds3502.wiper)
    voltage = wiper_output.value
    voltage *= 3.3
    voltage /= 65535
    print("Wiper voltage: %.2f"%voltage)
    print("")
    sleep(1.0)
