Summary of ALPHANUMERIC DISPLAY DRIVERS CIRCUIT WITH PIC16F874 HI TECH C
This project describes an alphanumeric LED display driver circuit using a PIC16F874P microcontroller. The design integrates 74HC238 decoder chips and a MAX233 for communication, powered by an LM2940 regulator and a 9V battery. The system drives custom 15-segment displays via HiTech C compiler code with interrupt support, utilizing Eagle PCB designs and PALCE16V8 logic.

PICMICRO 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.
