Welcome to the PICAXE forum.
Thanks for the feedback and suggestions.
I have recently added some extra chips to my DIPTRACE library (yet to be uploaded) and will shortly add these to PEBBLE as well. They are/include the MAX7219, WS2801 & WS2803, PT6961.
I have been relatively busy completing work around a new house and in recent months working on a new project involving longer working hours. However, it is my intent to get back into PEBBLE soon and incorporate the bits I have and the suggestions put forward by other members where feasible.
