The loop controller automatically tunes a magnetic loop antenna, using a variable capacitor, maintains tuning as the VFO changes, and much, much more.
A complete description as well as documentation is available at Loftur's main loop controller page

These instructions will get you a working environment to compile and upload the controller firmware to a Teensy 3.2 microcontroller.
For Visual Studio Code and Platformio
- Install VS Code.
- Install the Platformio extension from the VS code marketplace.
For Arduino IDE
- Install the Arduino IDE
- Install the Teensyduino extension
- Select all libraries when installing.
- Install the TMCStepper library.
- Download the repository as a .zip file. Name it TMCStepper.zip.
- In the Arduino IDE, navigate to Sketch -> Include Library -> Add ZIP library and select the ZIP file downloaded.
Connect the teensy to the computer running your development environment.
VS Code Open the repository folder in VS Code. Platformio should load and install all required modules automatically.
From the platformio menu, click Build and/or Upload.
Arduino IDE Open ML_v4.ino in the Arduino IDE
Click the Verfy (check box) or Upload (arrow) buttons in the arduino IDE.
- Verify compiles the code.
- Upload compiles and uploads the code to the teensy.
