Determining the Virtual COM Port

The programming or development tools such as MAX-IDE must be configured to work with the virtual COM
port (VCP) interface provided by the MAXQ2000 USB Thumb Evaluation Kit. First, you must determine which
COM port the operating system assigned to the USB serial port. To do this, click Start 

 Control Panel and

select System 

 Hardware 

 Device Manager. Look in the Ports (COM & LPT) section to determine the

COM port number assigned to the VCP (

Figure 3

).

Figure 3. USB serial-port COM location in device manager.

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.

Installing the MAX-IDE

The MAX-IDE program is a full-featured, application development and debugging environment for MAXQ®
microcontrollers. It works with all MAXQ EV kits and provides the following features.

Project-based development environment for MAXQ assembly applications.
Integrated MAXQ macro assembler, including standard header files for all MAXQ microcontrollers.
In-circuit application loading using the JTAG/TAP interface and ROM bootloader (for MAXQ
microcontrollers with flash or EEPROM program memory).
In-circuit debug features include setting break points, step-by-step program execution, and
memory/register content viewing and modifying.

The MAX-IDE program is installed like the USB drivers by using the MAXQ2000 EV kit USB flash drive.
