Alphanumeric Display Driver

The display pictured below is driven by a PIC microcontroller programmed to interface 15 segment LED displays.

LED displays on Digikey for fun but soon realized I’d need a driver chip to make use of them. Maxim offers many nice drivers for matrix displays and 7 segment displays, but if you need a custom driver for a random display (such as the 15 segment displays I bought) you may have to design your own. It’s not difficult, and here you can find some code to work with the PIC series microcontrollers using interrupts.
