APPLICATION NOTE 4277
Getting Started with the MAXQ2000 USB Thumb
Evaluation Kit
Sep 24, 2008
Abstract: This application note describes the necessary steps to quickly begin using the USB Thumb
Evaluation (EV) Kit for the MAXQ2000 RISC microcontroller. The document explains how to install and
configure the kit's hardware and software, and how to create and load applications that can be executed by
the on-board MAXQ2000 microcontroller. An example program to read and display ambient temperature is
provided.
Overview
The
MAXQ2000 USB Thumb Evaluation Kit
is a proven platform for conveniently evaluating the
MAXQ2000
RISC microcontroller. The evaluation (EV) kit board is a small "thumb drive" form factor with a USB interface
(Figure 1). By installing the MAX-IDE assembly language Integrated Development Environment on a
connected computer, applications can be developed and debugged on this EV kit board. The MAX-IDE
program is available on the USB flash drive included in the kit or by
download
from the Maxim website.

The MAXQ2000 USB board includes a DS18B20 temperature sensor; a 4-digit 7-segment liquid crystal
display (LCD); a 32kHz crystal for the MAXQ2000's internal real-time-clock (RTC); and a prototyping header
that provides access to some of the processor's general purpose I/O pins.
The evaluation kit is shipped with this board plus a USB flash drive containing software, schematics, data
sheets, and other valuable documentation.

Page 2: Software Setup
If the program does not start automatically, explore the drive, and double click the Setup.exe file in the root directory. This will bring up the MAXQ2000 EV kit main menu shown in Figure 2. - Page 3 In this case, the USB serial port was assigned to COM4. When starting MAX-IDE for the first time (or any other program that communicates with the MAXQ2000 EV kit), the IDE must be configured to use this COM port. This configuration process is described in more detail below. For now, simply record the COM port assignment for later configuration.

Page 4: Example Program
To load and execute this example, the files should be copied to a working directory on your PC. This is accomplished by clicking on the Programming Tools button from the main menu of the MAXQ2000 EV kit disk, and then clicking on the Example Code button. This will start an installation wizard (this may take a while),... -

Loading the Executable File There are several ways that an executable program file can be loaded into and run by the MAXQ2000 EV kit board. For instance, one can load a .HEX-formatted file using the Microcontroller Tool Kit (MTK) available on... - Page 6 Figure 5. Project loaded and ready to run. To load and run the application, click the run button at the top of the screen (highlighted in Figure 6) or press F5. The program will be loaded as indicated by the messages at the bottom of the screen, and it will begin execution from address zero.
