Introduction

Congratulations on your purchase of the ATMEL ATAB542x “Wireless BlackBird“ Trans­ceiver Demonstration Kit. This kit is built around the ATA542x RF transceiver IC and the
ATmega3290 AVR

This User Guide describes the Demonstration Kit features and provides two versions of
the menu system in the demo software – (1) an abridged version which gives the top
two tiers of the menu, and (2) an exhaustive version which gives the menu in full detail,
including the resulting action from all possible joystick movements at each point in the
menu.

For the most rapid path to executing a working demo with the transceiver pair, see the
Quick Start Card included in the package. It shows how to execute the Link Quality
demo – a demo in which each transceiver in the pair measures and displays the relative
signal strength of the other transceiver’s RF transmission.

1.1 Purpose The Wireless BlackBird kit, consisiting of a pair of transceivers, was designed with a

positive out-of-the-box experience in mind. Using the Quick Start Card included in the
package, an end-user can, within a matter of minutes, have a demonstration running.
This User's Guide outlines the demo-software menu, providing a complete, single docu­ment which the end-user can reference while becoming intimately familiar with the many
features of the demo.

micro-controller.

Equally so, this kit is suitable for a developer who wishes to explore the full capabilities
of the ATA542x radio and the AVR micro-controller. Through the ISP, UART, or JTAG
interface, the developer has complete control.

1.2 Description The ATMEL Wireless BlackBird is a 2" x 3.5" PC-board transceiver using the ATA542x

UHF transceiver IC and the ATmega3290 AVR micro-controller, as shown in Figure 1-1.
It is offered in five frequencies: 315, 345, 434, 868, and 915 MHz. The BlackBird is
UART-, ISP-, and JTAG- ready. It has a custom LCD display, a 4-way joystick, and is
powered by 2 AAA batteries.

The UART, ISP, and JTAG I/Os allow end-users to load software into the AVR and to
interface with the ATA542x radio. With the joystick, the end-user can navigate through
menus and select functions to execute. The LCD displays the menus, as well as show­ing transceiver activity during each of the various demo functions.

Section 2

Operating the Transceivers

This section contains remarks about how the Menu Guides, both abridged and exhaus­tive, are set-up and how to use them. Then, both versions of the Menu Guide,
respectively, are given.

2.1 Menu Guide Description

These menu guides are intended to provide the user with two views of the demo-soft­ware menu. First, the abridged version shows a top-level view of only the first two tiers
of the menu system. At a glance, the user can see what features are demonstrated in
the pre-loaded software. Second, in the exhaustive version, the user has a simple-to­navigate outline with complete details about each feature in the software. Additionally,
in the exhaustive version, short instructions are given for the demonstrations whose
execution is not intuitively clear from simply the outline material alone.

The following are comments important to understanding these guides and navigating
the Demo software menu:

1. anything that appears on the LCD display is highlighted in the outline with bold
text. This helps the user to more quickly spot the place in this outline that corre­sponds to the current position in the menu system while using the Wireless
BlackBird.

2. there are 5 possible movement of the joystick:

P - press

L - move left

R - move right

U - move up

D - move down

that result in some action. Each is described in the exhaustive version.

3. where reasonable, a few sentences of explanation either complement or replace
the abbreviated descriptions of the joystick movements.

4. unless otherwise stated, these actions apply to each menu item:

L - backs out of the menu item

P - starts/ends/selects the menu item

So, a very important action that the user MUST remember is:

only by pressing (P) the joystick will a selected menu item be stored in
memory!

Operating the Transceivers

5. the letters "X" or "x" are used in this outline to indicate display of a number that
has a variable value.

2.2 The Abridged Menu Guide

There are 6 main menus:

DIAGNOSTICS
LINK QUALITY
TEMPERATURE SENSOR
LIGHT SENSOR
FREQ HOPPER
SYSTEM SETUP

They are accessible by moving the joystick downward (not to be confused with pressing
it) or upward after power-up. At each main menu which has sub-menus, these sub­menus can be accessed by pressing the joystick. Moving the joystick leftward backs out
of the currently-selected sub-menu.

These 6 main menus and each one’s sub-menu are described here:

DIAGNOSTICS - provides transmit and receive functions for testing and evaluation.
The sub-menus are:

MARK - transmits a continuous logic "1" (the upper FSK frequency)

SPACE - transmits a continuous logic "0" (the lower FSK frequency)

TOGGLE - generates a continuous square wave by toggling between MARK and

SPACE (FSK mode)

RSSI - indicates received signal strength

PKT TX - transmits packet data

PKT RX - receives packet data

S LINK - serial link mode; permits two PCs to communicate over an RF link

LINK QUALITY - two transceivers exchange data packets with one-another. Each trans-

ceiver displays the relative strength of the signal it receives.

TEMPERATURE SENSOR - two transceivers exchange with one-another the tempera­ture measurement made by each’s on-board sensor. The temperature measured by a
transceiver’s own sensor, as well as that reported by the other transceiver, is displayed.

LIGHT SENSOR - two or more transceivers exchange with one-another the light inten­sity measurement made by each’s on-board sensor. This is a multi-transceiver
demonstration with a single MASTER and one or more REMOTEs. The intensity mea­sured by a transceiver’s own sensor, as well as that reported by the other transceiver, is
displayed. NOTE: the REMOTEs communicate only with the MASTER – not with other
REMOTEs.

FREQ HOPPER - two transceivers exchange data packets, in either single or continu­ous mode, as they hop among pre-set channels.

HOW TO EXECUTE THE “S LINK” FEATURE: Connect the BlackBird's 3-pin UART
header to a PC with a suitably-modified serial RS232 cable. (NOTE: For "RF sniffer"
applications, only one such set-up is required. To communicate between two PCs via
an RF link, do two set-ups.). Using the Terminal Emulator included on the CD (or,
another suitable one), configure the serial port for 38.4k, N, 8, 1. In the S LINK menu,
select the desired CH x, ASK or FSK, x KBPS, and ASCII mode for one of the trans­ceivers. When the LCD displays SL ON with a blinking antenna icon in the lower left­hand corner, the device is ready for communication. Repeat this with the 2nd trans­ceiver. Now, type on one PC and observe the packet data displayed on the other PC.
NOTE: in order to command the transceiver to transmit the message, one must hit
<ENTER> on the keyboard.

L - goes to TEMPERATURE SENSOR

R - puts transceiver into MASTER mode

HOW TO EXECUTE THE “TEMPERATURE SENSOR” FEATURE: One transceiver
should be left as a REMOTE at the *WAIT*, antenna icon (blinking) display. When
the other transceiver is put into MASTER mode, it starts sending packets and estab­lishes communication with the REMOTE. The MASTER cycles through 3 screens: (1) M

TEMP, with AVR lo g o and antenna icon (blinking), and a thermometer icon, (2)
LOCAL, the measured temperature at the MASTER, and the thermometer icon, (3)
REMOTE, the reported measured temperature at the REMOTE, and the thermometer
icon. The REMOTE will cycle through the same 3 screens as the master, displaying R
TEMP instead of M TEMP.

During any of these 3 screens, on either the MASTER or SLAVE:

L - returns TEMPERATURE SENSOR

U - toggles the displayed temperature between F and C

2.3.4 LIGHT SENSOR Exchanges and displays measured light intensities

P - sets number and puts radio into MASTER mode

L - puts radio into MASTER mode

U,D - changes number of sensors to poll (1 - 254)

HOW TO EXECUTE THE “LIGHT SENSOR” FEATURE:

SINGLE-SENSOR mode: After one transceiver is put into MASTER mode, the MAS­TER polls the REMOTE with ID #1. The MASTER starts sending packets and
establishes communication with the REMOTE. The MASTER cycles through 3 screens:
(1) M LIGHT, with AVR l ogo and antenna icon (blinking), and a 4-digit number, (2)
LOCAL and a 4-digit number, (3) REMOTE and a 4-digit number. The REMOTE
cycles through the same 3 screens as the master, displaying R LIGHT instead of M
LIGHT and no 4-digit number.

MULTI SENSOR mode: This mode is similar to the SINGLE SENSOR mode except that
each successive transmission addresses the next incremental REMOTE ID, up to the
largest ID # set in the MULTI SENSOR menu. In order to do this mode successfully, a
specific power-up sequence is required. For example, if the largest ID # is set to 3, the
MASTER will poll REMOTE 1, then REMOTE 2, then REMOTE 3, and the repeat con­tinually until the demo is terminated.

Operating the Transceivers

HOW TO EXECUTE THE “FREQ HOPPER” FEATURE:

SINGLE-EVENT mode - at the M HOP screen, pressing the joystick sends a packet on 3
of the 5 pseudo-randomly-selected pre-set channels. The display shows M HOP, AVR
logo, and CH-x. CH-x displays the channels on which it received a valid return packet
from the REMOTE. Conversely, "----" indicates the data on that channel was not valid.
During this mode, the REMOTE displays a 4-digit number if it receives at least one
good packet of the three.

CONTINUOUS mode - at the M HOP screen, moving the joystick up (until the snow-
flake is visible) continuously sends packets as the MASTER hops among the 5 pre-set
channels. The display shows M HOP, AVR l o g o, snowflake, and CH-x. During this
mode, the REMOTE displays a 4-digit number if it receives at least one good packet of
the three.

In this demo, the REMOTE scans the 5 pre-set hop channels, goes to sleep, then
repeats. These pre-set hop channels are not to be confused with the channel number­ing in other user-selectable menus.

2.3.6 SYSTEM SETUP contains ten “house-keeping” functions

sub-menus: PWR DWN, CHANNEL ADJUST, UNIT ID ADR, SET DATE/TIME, PWR

HOW TO EXECUTE THE “CHANNEL ADJUST” FEATURE: when the transceiver is
transmitting, change the 4-digit number with the joystick movement until the desired
operational frequency is reached. Each increment in the hexadecimal number trims the
transmit frequency about 1kHz.

2.3.6.3 UNIT ID ADR Assigns a unit ID to the transceiver

Note: for REMOTEs only -- the MASTER is always assigned ID #0

Note: this utility can be used to manually set the REMOTE IDs for the LIGHT SENSOR

Appendix

3.1.1 Software re-load and FUSE settings

If at any time the software for the BlackBird needs to be re-loaded, please use the file:

CD:\software\IARSRF_B100.hex

In addition to programming the BlackBird with the executable software, the FUSEs must
be correctly set. Here are the FUSEs which need to be checked, in text and with snap­shots of the pop-up from AVR Studio.

brown-out detection @ 1.8v

JTAG interface enabled (optional)

SPI enabled (may be ghosted – that’s OK)

boot reset vector enabled

divide clock by 8 internally

boot flash section size = 2048

int RC oscillator: 6CK + 65ms

Note: if minimum current-consumption is desired, uncheck “brown-out detection @ 1.8v” and

“JTAG interface enabled”.

3.1.2 Software documentation

To facilitate understanding the source code, it is recommended that DOXYGEN soft­ware (http://www.doxygen.com) be used to generate documentation. A file called
“Doxyfile” is on the CD in the software directory. This file will be helpful when generating
documentation with DOXYGEN.
