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 .env
source .env/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)
