A quick note to let you know that courtesy of David Mills, G7UVW, the Etherkit Si5351 Arduino library has now been ported to the Mbed platform. He reports that it seems to be behaving the same as the Arduino library, so if you’re an Mbed user, definitely go check it out. I was giving some consideration to making this port, but I’ve got so much other stuff on my plate at the moment that I just hadn’t got around to it yet.
Three cheers to David for this! Huzzah! Huzzah! Huzzah!
