APPLICATION NOTE 3688
Using the MAXQ2000 with the MAX6960 to Create a
Stock Quote Display System
By: Ted Salazar, Applications Engineering Manager
Dec 23, 2005
Abstract: This application note provides everything you need to implement a stock quote display system
based around the MAX6960 display driver and the MAXQ2000 microcontroller (MAXQ20 core). Included are
schematics, Windows software, and microcontroller firmware. The example firmware is an assembly program
written and assembled specifically for the MAXQ2000 using the free MAX-IDE. (Version 1.0, Build Date: Nov
18 2004). Download the free MAX-IDE from Maxim's website.
The stock quote display system.
MAX6960 Overview
The MAX6960 is a graphic LED, tile display driver capable of driving 8x8 LED tiles. This application note
uses twenty MAX6960 devices to drive twenty 8x8 LED tiles to display the Maxim stock price. The Windows
software and microcontroller firmware can be easily modified to display your company's stock price and
symbol.
Hardware Overview
The application circuit utilizes five cascaded MAX6960EVKITs and one MAXQ2000-KIT. Figure 1 shows the
hardware system block diagram for this setup.
