Yes to all of those– and thanks!
A few more points of interest, too:
– PD7 is “designated” as a place for an extra LED, but is actually also available for hacking in any way that you like.
– PD0 and PD1 go to an extra serial interface (J5). We plan to use this for serial data out, for daisy-chained displays, in the next firmware revision, but you’re also welcome to repurpose those in any way that you see fit. :)
– O10 – O15 can potentially be used to drive additional LED “segments,” should that happen to come in handy.
