Check out the forums for all the v2.4 code and documentation.
Note: This code is for the new display type (TM1637 controller). If you have the old display type (HT16K33) from Adafruit, this code will not work.
I'm currently updating the code for the old display type and will publish in a day or so when I get the last bugs worked out. Going forward, I am phasing out the old display. The pin-out is exactly the same if you want to upgrade to the new display type.
