7-segment led - Digit display on car windshield

Hi, I want to display number by 7-segment led in reverse order like this, please advise if there is already library to use. by the way I use this unit http://www.seeedstudio.com/wiki/Grove_-_4-Digit_Display


Thanks, I have configured out how it works and made changes to the library. it works.

I am facing another problem that the 7 segment led display in ITALIC. this means its reflection looks urgly thru the windshield.

where can I buy 7 segment led NOT in italic? its best if i can buy leds designed especially for this purpuse.

Yes you can buy straight ones look at a major distribuitor like Farnell or Digikey or Mouser.

Or a supplier of LED displays like http://www.kingbrightusa.com/
