The design for the Display module has been kept as simple as possible, so that it does not limit the possible display types.

Just the interface to the Core module is defined:

Power:

  • Vcc (5V)
  • GND

Datalines:

  • SER
  • RCLK
  • SRCLK
  • SRCLR

The naming convention was taken from the Texas Instruments Data Sheet for the SN74HC595 shift register, which was the IC driving the first LED display modules.

The data transmission order is Row data [Least Significant Bit first], Coloumn data [Least Significant Bit first].
