Thanks for the suggestions. Wish I could have done the karma button. I'm afraid I am a recent ex Picaxe user and I'm afraid much is still going over my head
Do I leave the crystal in when connecting the jumper to X1?
Could you please explain what (and how) I must run from serial monitor.
I have downloaded the link you posted and clicked on the "board programmer .ino" file. It opened the arduino window and I uploaded the code. A string of serial data should be displayed but only a single letter comes up?
