Introduction

1.1 AVR STK100

Starter Kit

The STK100 Starter Kit is designed to support the AVR Microcontroller from Atmel Cor-

poration. The system will help tiny AVR users to get started designing with AVR

Microcontrollers.

The STK100 incorporates an In-System Programming unit and an applications board.

For late breaking news and any manual errata always check the README.TXT file

included with the software or check the Atmel web site for any updates.

1.2 Device Support The system software currently has support for the following devices.

■AT t i n y 1 0

■AT t i n y 1 1

■AT t i n y 1 2

■AT t i n y 1 5

■AT t i n y 2 2

■AT t i n y 2 8

■AT90S2343

Upgrades for new devices will be available via the Internet at www.atmel.com.

Getting Started

2.1 Unpacking the

System

You will find the following items in the pack:

■STK100 main board

■1 disk set

■Parallel/printer port cable

■ATtiny11 sample + AT90S2343

■Atmel CD-ROM

2.2 System

Requirements

The minimum computer hardware and software requirements are:

■80486 processor or above

■16 MB RAM

■2 MB free hard disk space

■Windows 95/98 or Windows NT

2.3 Power Supply 9.5 - 15-volt DC power supply with 3.5 mm barrel connector, center positive or 7 - 13-

volt AC power supply with 3.5 mm barrel connector.

Note: If the regulator or other IC runs too hot, reduce the input voltage. The specially

formulated ink used on the STK100 will turn darker if subjected to heat to indi-

cate hot spots. It will turn lighter when the heat source is removed.

2.4 Connecting the

System

The system has two separate connections to the PC either of which may be used for

running or programming Tiny AVR devices on the STK100. The connectors for serial

and parallel port are next to each other on the STK100 board.

The two connections are serial 9-pin “D” connector connecting to the serial port or paral-

lel 25-pin “D” connector connecting to the parallel/printer port. The programmer software

must be configured for the correct connection. This is described in Section 6, “How to

Use the Software”.

Note that in order to update the internal firmware on the STK100 for new device support,

the system must be connected to the parallel port.

Getting Started

2-2 STK100 Starter Kit User Guide

Updates will be added to the Atmel web site as new parts become available.

A parallel port cable is supplied with the system to allow this port to be used for

upgrades. If you prefer to use the serial port, a straight-through serial cable is required.

Do not use a null-modem cable with crossed connections.

The software must be configured for either serial or parallel port operation, and the

correct port chosen: LPT1, COM1, etc. See Section 6, “How to Use the Software”for

details.

Please read the next section, “Hardware Description”, before using the programmer in

STK100.

Section 4

Device and Jumper Information

Please refer to Figure 9-2, “Targets and Interfaces Schematic”, found in Section 9,

“Appendix A –STK100 Schematics”.

The system has four sockets for devices:

■28-pin socket

■20-pin analog socket

■8-pin digital socket

■8-pin analog socket

These sockets have been configured to accept all of the current and future AVR Tiny

devices. Please choose the correct socket for the device to program.

The STK100 features two types of programming. It will use either low-voltage In-System

Programming (ISP) or high-voltage parallel programming, depending on the part. There-

fore, it is essential that the user inserts the device into the correct socket and chooses

the correct device type from the programming menu on the PC. Failure to do so may

result in damage to the device and possibly the system.

4.1 Device

Orientation

Before programming a device using the programming module, the device must be

inserted correctly into the programming unit. The AVR device itself has an arrow printed

on it, which points towards pin 1 of the device. Below are the three types of sockets and

their orientation.
