The Raspberry Pi is a low cost device which is found in many households. A powerful feature of the Raspberry Pi is the row of GPIO (general-purpose input/output) pins along the top edge of the board. These GPIO pins can be used to interact with the LoctekMotion control box.
In the end I believe the Raspberry Pi is overkill for this scenario, but if you have a spare one or if you want to experiment, give it a try. The Python script in this part is limited, but can easily be extended to fix your scenario.
- Raspberry Pi (with GPIO headers)
- Material to connect to the RJ45 port
Connect the GND, TX, RX and PIN20 (see README) to the Raspberry Pi. In the Python script we use the following pins, but you can adapt this to your wishes.
| Raspberry Pi | Loctek Motion |
|---|---|
| 6 | GND |
| 8 (GPIO 14) | RX |
| 10 (GPIO 15) | TX |
| 12 (GPIO 18) | PIN 20 |
Run raspi-config to turn on the serial connection. Go to Advanced Options -> Serial and enable the serial connection. You don't need to enable it for login.
sudo apt-get install python3-rpi.gpio
Browse to the folder where you placed the flexispot.py file.
python3 -m venv venv
