TM1637_6Digit

This is open source TM1637 6 DIGIT Display , Driver for 6 digit 7-segment display modules, based on the TM1637 chip.
These chips can be found in cheap display modules. They communicate with the processor in I2C-like protocol. The implementation is pure software emulation and doesn't make use of any special hardware (other than GPIO pins). It is assumed that pull-up resistors are present (usually integrated in the display module).
