As mentioned elsewhere the new library for the SI5351 has minor changes to the calls. This causes compile errors if you just download the sketch and library.
I've made a new folder in the files section and added the BitX40 sketch with minor changes to suit the new library calls.? I've also put the library zip file there for completeness.
I hope to make a video of the steps necessary to upload the sketch to the Arduino Nano in the raduino.? That way any glitches requiring a re-program can easily be followed by anyone not familiar with Arduinos.
