First version of serial SPI loading code
First version of SPI serial loading that works.
Cleaning up the load code. Fixed alignment issues
Test code before more code removal
Works when latching flag is declared as a register
Work in progress
Now have CPU divider set in the makefile
Simplified the latching function
Testing code
Fixed loading errors
Finished testing program checkins
Cleaned-up version of the working serial loader: blanks are not set yet.
In a single-unit environment the graphic data is now loaded correctly (finally!)
Now walking backwards in the channels, palette order is RGB again
this version illustrates volatile problems
Cleaner version of non-working code
Fixed two multi-unit bugs
Change SPI speed to maximum
272 -> 38 speed improvement by changing nBitsSent to be 16 bits instead of 32
38 -> 22 clocks speed improvement in load function
by changing nBitsSent to nBytesSent
and changing its type to 8 bits.
