Microcontroller to Scroll Messages
A circuit and program listing for using the MAX6955 LED display driver with
a PIC microcontroller and 14-segment displays.

The MAX6955 is an LED display driver with an I2C-compatible, serial interface capable of
supporting Fast Mode speeds up to 400kHz. It is capable of driving sixteen 7-segment, eight 14-
segment, eight 16-segment or 128 separate LEDs. This application note describes a 14-
segment application circuit and an example program that continuously scrolls the message:

"THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG".

The program, shown in Listing 1, can be modified to scrol……
