API for the TM1637 7-Segment Display. More...
TM1637 is a display controller for LED-based 7-segment displays. It can be used to address and write data to multiple display digits. This driver is based on the Grove version of the TM1637 display that uses 4 digits, thus making it ideal for clock displays, timers, counters, or even score displays in a two-player arcade game.
