A seven-segment display (SSD), or seven-segment indicator, is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.
This is a simple seven segment library that let you display char / numbers, or any sequance you need to multiple display.
It runs both on common anode, and common cathode display.
I've used a lookup table to convert ascii table. Also a function to display any sequence you want is available.
Below you can find sample schematics to run multiple diasplay.
The full transistor version let you run disaply at your desired voltage.
