Hey Mark ,

yes got some of those on the way for a test , this guys has added is own brew of SPI interface to the unit with some custom coded commanded for graphic usage in the pic chip interface , he is very shy when it comes to real details on timing of the interface for the spi , hold times etc , think he just never did the timing charts.

i am hoping that using a graphic display for a fast counter , will refresh quick enough not to jump , and adding a spi to the display wont slow it up to be an issue

strange that a simple glass lcd or digit led is often a easier for large digit display usage still
