Materials

Hardware

Raspberry Pi and any other cables you'll need!
Wireling Pi Hat
(1) Wireling Cable
Rotary Switch Wireling

Required Software

Python 3 (Python 2 is not supported!)
All Python packages mentioned in the Pi Hat setup tutorial (tinycircuits-wireling, Adafruit-Blinka, adafruit-circuitpython-ads1x15, and adafruit-circuitpython-busdevice)
SX1505 Python Package (Used for both the Joystick and Rotary Wireling)
Rotary Python Example

Hardware Assembly

Plug your Wireling into the port you plan on using! The default in the included program is port 0.

If you want to use a different port, you just need to change the port value in the program mentioned later.

Programming

Install the necessary Python package:

pip3 install tinycircuits-sx1505

Then you can download (above under Software) the Rotary Wireling example:

rotary-example.py

# Rotary Wireling Example
# This example will print out the numbered direction the Rotary is toggled
# Written by: Laverena Wienclaw for TinyCircuits

import tinycircuits_sx1505
import tinycircuits_wireling
import time

wireling = tinycircuits_wireling.Wireling()
wireling.selectPort(0)

rotary = tinycircuits_sx1505.SX1505()

while True:
    position = rotary.getRotaryPos()
    print("Number direction: {}".format(position)) 
    time.sleep(.5)

Run Program

Navigate in the terminal to the directory with the file parent to the examples folder.

python3 rotary-example.py

Once the program is running, the number the rotary is pointing to will be printed out.
