tm1637-fpga

4-Digit 7-Segment Display for FPGAs

Module uses functionally reduced Version of I2C (no bus identifier number)

This "bit-banging solution" was developed by sniffing on example communication with an Arduino board with a Logic-Analyser, a pen and a piece of paper.

For the most recent version have a look at: https://opencores.org/projects/tm1637
