Arduino + 4x MAX 7219 + 7-Segment

I want to build the displays of my MCP with Arduino Mega and the MAX7219 shift registers. Each shift register controls a six-digit seven-segment display with common cathode.

Seeking a Arduino sketch that reads the values from the serial port and outputs to the respective seven-segment displays. Unfortunately I have not found on the various websites Arduino, this helps me. I dont want to use a system like MobiFlight.

Hi,

Check out my software: http://737ng.info/post/73

I'm using it with my MCP to control 3 daisy chained MAX7219.

Thank you for your post but I'm done with both the software and the hardware to 90%.
