Initialising EEPROM

You must initialise your Arduino's EEPROM before this script will work!

The script reads a table of information during setup, so before you run the main Arduino_si5351_VFO_Controller.ino for the first time, you must run the Initialiser script once. If you don't do this, the VFO Controller script will give unpredictable results!

The Initialiser script writes default values into the first few hundred bytes of the EEPROM.

Running Initialiser

Open the file Initialiser.ino and compile and download it. Let it run for a few milliSeconds or so. If you open the Serial window you can see the default values it is writing. Then, download the main VFO Controller script, and it should run as expected, starting on VFO 4, 7090 kHz.
