Introduction

Congratulations on your purchase of the AT43DK355 USB Development Kit. The

AT43DK355 is a complete starter kit and development system for Atmel's AT43USB35x

family of AVR®based USB microcontrollers (MCUs). It provides all of the necessary

hardware and firmware components to facilitate rapid prototyping and firmware develop-

ment of the AT43USB35x applications.

1.1 Features The AT43DK355 Development Kit consists of the following:

Development Board for the AT43USB35x USB MCUs featuring

– An AT43USB355 full-speed USB controller programmable as a compound

device, a hub only device or a function only device

– One internal and two external downstream HUB ports

– 1 Kbytes on-chip program SRAM

– 24 Kbytes of program memory

– Parallel interface to PC for In-System firmware programming

– 8 push buttons and 8 LEDs for general use

– Pin header connectors for access to all available GPIO pins

Hardware design files (schematics and PCB layout)

USB 2.0 compliant USB firmware library

USB Wizard firmware source code generation utility

In-System Programming tool

Complete User Guide

1.2 Device Support The AT43DK355 Development Kit and the accompanying software tools are intended to

support firmware development and prototyping for the AT43USB35x family of USB func-

tion controllers, including the

– AT43USB355

– AT43USB353M

– AT43USB351M

Introduction

1-2 AT43DK355 USB Controller Dev. Kit User Guide

3429C–USB–7/04

Binary compatibility across the AT43USB3xx family ensures that only one set of devel-

opment tools (development kit, compilers, etc.) is needed for all of the AT43USB3xx

based applications. Firmware written for one member of the family can be re-used for

another member without modification as long as only features available on both parts

are used.

1.3 Documentation The AT43DK355 Development Kit is accompanied by the following two documents:

– AT43DK355 User Guide

– USB Wizard User Guide

Atmel recommends its customers read the AT43DK355 User's Guide prior to reading

the USB Wizard User Guide.

1.4 Free Downloads The latest version of the USB Wizard can be found in the USB section of the Atmel web

site at http://www.atmel.com. Please refer to the same section for up-to-date informa-

tion on new USB product announcements, software releases and tool upgrades.

–128MBRAM

– 10 MB free hard disk space

– Windows®98/2000/ME/XP

– Parallel printer port

2.4 Software

Requirements

The following third party software are needed to access and modify the documents and

source code in the CD-ROM:

–OrCAD Capture®from www.orcad.com for the .dsn file

–IAR or GNU C Compiler for the sample C source code

–Microsoft®Word from www.microsoft.com for the .doc files

–Acrobat®Reader®from www.adobe.com for the .pdf files

–Winzip®from www.winzip.com to open the .zip files

2.5 Connecting the

Hardware

Atmel has taken great care in creating a reliable demonstration kit for its customers. The

AT43DK355 Development Board is USB bus powered and requires no external power

supplier. In order to ensure proper operation, the supplied components in the kit must be

used in the setup shown in Figure 2-1. Atmel does NOT recommend substitution of

these components.

Connect the AT43DK355 Development Board as follows:

1. Verify that Jumper JP8 and Jumper JP11 are closed.

2. Connect the USB cable from J1 Series B USB receptacle on the Development

Board to the USB Series A receptacle on the PC.

3. Connect the DB25 parallel cable from J4 on the Development Board to the paral-

lel port on the PC.

2.6 CD-ROM

Contents

The CD-ROM has a top directory \355_evx\ where xindicates the version of the firm-

ware. All the directory paths used in this User Guide fall under this top directory. There

are three major subdirectories:

–BOARD: hardware design documentation

–Docs: datasheets, tutorial, and user guide

–USBWizard: USB Wizard software tool and examples

2.6.1 USB Wizard Utility USB Wizard utility is a GUI based development tool that facilitates rapid USB application

development for the AT43USBxxx family of AVR USB controllers. It allows the user to

generate firmware templates in ANSI C for USB and AVR®peripherals with few clicks of

the mouse.

This utility is located in \USBWizard\USBWizard direcotry. This directory contains the

USB Wizard executable file and other dependencies files.

Please refer to the Readme file on the release CD for the installing instructions. The

USB Wizard executable file is supported on Windows®98/2000/ME/XP.

Source code generated by the USB Wizard cannot be programmed directly into the on-

board SEEPROM device. It must be compiled and linked first. The USB Wizard currently

supports IAR and GCC compilers.

Refer to the Atmel “USB Wizard User Guide” and “USB Wizard: Application Examples

and Demos” for detailed descriptions of this utility.

Figure 2-2. USB Wizard Application Window

2.6.2 Code Base Directory This is the directory where all code base needed by USB Wizard are taken from. The

name of this directory is \USBWizard\Codebase. There are two main groups of code

base within this directory. The first one is IARbase, which provides necessary code for

IAR. The second one is GCCbase which contains the code for the GCC compiler. The

following is a brief summary of directory tree of this code base.

Code base

|------------ IARbase

| |------ AT43USB35x

| |------ AT43USB326

| |------ AT43USB325E

|------------ GCCbase

|------ AT43USB35x

|------ AT43USB326

|------ AT43USB325E

2.6.3 Application Example The application examples are also included within this package. They are located in

\USBWizard\Examples\ directory. This directory contains USB Wizard configuration files

(*.usw files) and the corresponding C files for application examples. There are five sub-

directories in this directory:

1. PWM_ADC_GPIO

2. OCR1A

3. OCR1B

4. SPI

5. Hub_Disabled

2.6.4 In-System

Programming Tool

The SEEPROM Loader allows developers to program the SEEPROM device through

the standard parallel port. The tool is located in \USBWizard\ISP\ directory.

Please refer to the Readme file for installation instructions.

Please read Section 4 of this document or Section 3 of Atmel USB Wizard: Application

Examples and Demos on how to use this utility.

Figure 2-3. SEEPROM Loader Tool Window

2.6.5 Atmel USB HID

Demo Utility

This tool, located in \USBWizard\Demo_Utility\, is purposed to exercise the functionality

of application examples.

To install it, copy and paste the executable file in this directory to the desired location.

How to use this utility will be fully explained in Atmel USB Wizard: Application Examples

and Demos especially for example 1 (PWM, ADC, and GPIO).
