basically SPI.transfer does `while (!(SPSR & _BV(SPIF)))` and for some reason this spin locks never returning. (suspected bad firmware that does not ack properly?) changed to use the demo code's method of transmitting SPI data and it worked fine.

Also ran into an issue with SPI.transfer, (again possibly due to how the new avr-gcc does some things and the current firmware not being up-to-date but kinda workable?) made a work around that I can't see any issues with so far. |
…k?)" Turns out that something else is causing issues and my fix was only intermittent? gah...
…right time. My testing of trying to fix it before hand was actually setting up SPI in the wrong order, hence how I missed it. And how that other commit got by me: stale data in the matrix from other testing (I *thought* I had reset it...)

Due to an update in 4.6.1 of avr-gcc prog_* and friends kinda broke.
this fixes that issue and makes all the data sets
constas they should have been.
