I loaded your code and it works fine.
What is the voltage from pin 19 to 4?

This is kind of interesting might be able to get some ideas here.

First your decoupling capacitor must be placed as near as possible to the power pin to ground on the 7219.
Give us a link to the display.

I am curious, how will this board be used?

EDIT:
If you enlarge the PCB add 6-32 mounting holes in the corners then you would have room for both the controller names and the IDE name side by side.

Your code works fine.

What display are you using?
Can you show us your wiring?

Windows 7 finds the driver good, getting the driver from China not sure if I would.

Not sure where to get the CH340 driver.
23  Using Arduino / Microcontrollers / Re: New Mega2560 Layout on: July 20, 2014, 01:16:17 am
I think the way you have it is best.
Would you want a jumper option on +5 on the the FTDI?
24  Using Arduino / Project Guidance / Re: 8 digit 7 segment display on: July 19, 2014, 07:40:43 pm
Use SPI.
See:

Also look into the 7 segment library.

Double check your wiring.
I don't see any de-coupling, do not omit them !

What is the frequency you measure on the scope.

Whenever I want to make a bezel for a project I do it up using Setchup.
Print off a 1:1 image of the layout on a full sheet on 8 1/2 by 11 inch Avery self stick label, stick it on the cover, drill, cut the hoes you need to.

What do you get if you print "data" right after you set it?

  if(Serial.available() == 25){
This doesn't read any characters!
Check into how you red a serial value if there is one to be read.

Turn on a high pressure water hose sweep it back and forth over the road surface for a period of time.

Put up a 1 foot high mesh fence on either side of the road . May be electric.
