Hello,

The driver is great, however I have been given the Mimio Xi protocol
documentation and it describes what all of the hex is doing. 
Unfortunately I am not at liberty to share the documentation with
anybody due to an NDA, however I would hope that the code will be fairly
clear as to what's happening as a lot of the protocol hex I have setup
as defines.

The initialisation sequence in the current driver is just a series of
hex codes which I am reimplementing as per the Xi protocol.  Also the
board has on-board flash for the boards layout, dpi and firmware based
upgrade methods.  I am going to implement access to these.

I am also, as you state, working on the X side of things. 

I certainly would not want to tread on your toes with regard to the
development of this driver, however as you had mentioned to me in the
past that you did not have the time to devote to this I decided to move
ahead with it myself.  Are you planing on making changes to the existing
driver?

Regards
Phil Hannent
