Introduction
Congratulations on your purchase of the AVR® ATAVRMC100 evaluation kit. This document describes the board included in the ATAVRMC100 starter kit dedicated to
AT90PWM3.
1.1
Overview
The ATAVRMC100 is an evaluation kit dedicated to brushless DC motor control, for
both Hall effect sensor control and sensorless control using Back ElectroMotive Force.
The kit includes an evaluation board, a 3-phase BLDC motor and a demonstration software. It allows users to quickly evaluate the capability of the AVR® microcontroller
AT90PWM3 to control high speed brushless DC motor applications.
The kit can also serve as a development platform. Low cost AVR development tools
make debugging easier, and source codes, written in C, can be easily re-used by developers for their own motor control applications.

Quick Start
The evaluation board is shipped with a AT90PWM3 microcontroller. The AT90PWM3 is
already programmed with demonstration code. The default jumper settings will allow the
microcontroller to execute a basic program that runs the BLDC motor of the kit. The
demonstration program in the AT90PWM3 is described in Section “Basic Test Program”, page 19.
Connect the motor as indicated below, motor phases (3 thick wires on pin 1,2 & 3) and
Hall sensors (5 thin wires on pin 4 to 8) .

Section 4
Programming ATAVRMC100
4.1
In-System Programming
The AT90PWM3 can be programmed using specific SPI serial links. This section
explains how to connect the programmer.
The Flash, EEPROM memory (and all Fuse and Lock Bit options ISP-programmable)
can be programmed individually or with the sequential automatic programming option.
WARNING: If debugWire fuse is enabled, AVR ISP can’t be used. If debugWire
fuse is disabled, JTAGICE mkII have to be used in ISP mode to enabled debugWire fuse.
4.1.1
Programming with AVR ISP Programmer
The AVR ISP programmer is a compact and easy-to-use In-System Programming tool
for developing applications with AT90PWM3. Due to the small size, it is also an excellent tool for field upgrades of existing applications. It is powered by the ATAVRMC100
and an additional power supply is thus not required.
The AVR ISP programming interface is integrated in AVR Studio.
To program the device using AVR ISP programmer, connect the 6-wire cable on the ISP
connector of the ATAVRMC100 as shown in Figure 4-1.
Note:
ATAVRMC100 User Manual
See AVR Studio on-line Help for information.

4.1.2
Programming with STK500
The AT90PWM3 can be programmed using the serial programming mode in the AVR
Studio STK500 software. The software interface (In-System Programming of an external
target system) is integrated in AVR Studio.
To program the device using ISP from STK500, connect the 6-wire cable between the
ISP6PIN connector of the STK500 board and the ISP connector of the ATAVRMC100
as shown in Figure 4-2.
Note:

can be programmed individually or with the sequential automatic programming option.
4.1.3
Programming using JTAGICE mkII
The AT90PWM3 can also be programmed using the JTAGICE mkII emulator in debug
Wire mode. In this mode, AT90PWM3 starts running code only when JTAGICE is disconnected. All software is available in AVR Studio.
ATAVRMC100 User Manual

4.2
Debugging
AT90PWM3 has embedded On-chip debugWire that allows emulation with
ATAVRMC1OO using JTAGICE mkII only.
WARNING: If debugWire fuse is enabled, AVR ISP can’t be used. If debugWire
fuse is disabled, JTAGICE MKII have to be used in ISP mode to enabled debugWire fuse.
