Jack is at ham fest and has limited access.? I am going to lock variables down for programming safety and try to speed up processing.? I am looking for upgrades also.

Is there a reason why SPI speed to the RA8875 is set to 10 MHz on JackAl?
or is this something that should be explored for better system performance?
This could be a simple oversight in library modification, since it is buried one directory level below and would not affect functionality.
I don't have hardware built to test, but I verified through adding a pragma message that in the lib RA8875\_settings\RA8875UserSettings.h
that?SPI_HAS_TRANSACTION is defined.
MK20 case sets MAXSPISPEED = 22000000UL
MK66 should be able to do the same (pending wire-up limitations, etc)
Currently not defined and it falls through to default.
Might make things a little snappier.? Might be a place to tune out possible harmonic issues. Speed might be limited to wire length and routing. Might be a total don't care. Might be that I am out to lunch figuratively, because I am literally.
Thought I would pass along the observation before I forget, and if this is an area for improvement, that others don't wait until I get around to building.
Also same if/else type statement in "_utility", but that doesn't appear to be used in the JackAl code.
