ok.. lets discuss the communication format/protocol they all use..
When I messed with the MAX7221 a 'little' bit..
the LedControl lib (for MAX72xx chips) is pretty easy/nice.. but someone showed me some SPI code to work with it as well..
(passing in binary 10011000 to create the 'pattern' I want to have on the led matrix/segment..etc..
one of my future projects is to try and mimic these animation effects:https://www.youtube.com/watch?v=I_KGca_g96U&noredirect=1
(they are using .net arduino (netduino) variant and a MAX chip I believe)..
(in the end I have questions about adding this type of functionality to my project as it basically is a nArduino & Waveshield.. which uses SPI /timers to play audio..etc)
anyways.. so I have a bit (tiny amount) of familiarity with workign with the MAX chip.. are there pre-made libraries for these other chips as well? and since they didnt note as being SPI format.. how do you control the chip? bring some pin hi/low.. write/edit some values..then bring the pin back hi/low so it 'upates' this data?
(sounds like SPI to my noob mind?)
