Does any of the currently available 1st and 3rd party firmware have an already implemented I2C:
- scrolling text (marquee) function
- print word (as opposed to single character) function
- whole frame bitmap upload via I2C (as opposed to a row mask)
- support for multiple rainbowduinos/matrices for all of the above?
Thing is, i was thinking of eventually building up a weather/e-mail/notification ticker and wouldn’t like to end up coding the above from scratch and then realising all of it was already done and available
