\defgroup esb The ESB Embedded Sensor Board
|
|
|
|
The ESB (Embedded Sensor Board) is a prototype wireless sensor network
|
|
device developed at Freie Universität Berlin.
|
|
|
|
<img src="img/esb/esb.jpg" align="right">
|
|
|
|
The ESB consists of a Texas Instruments MSP430 low-power
|
|
microcontroller with 2k RAM and 60k flash ROM, a TR1001 radio
|
|
transceiver, a 32k serial EEPROM, an RS232 port, a JTAG port, a
|
|
beeper, and a number of sensors (passive IR, active IR
|
|
sender/receiver, vibration/tilt, microphone, temperature).
|
|
|
|
|
|
The Contiki/ESB port contains drivers for most of the sensors. The
|
|
drivers were mostly adapted from sources from FU Berlin.
|
|
|
|
\section esb-getting-started Getting started with Contiki for the ESB platform
|
|
|
|
The ESB is equipped with an MSP430 microcontroller. The first step to
|
|
getting started with Contiki for the ESB is to install the development
|
|
tools for compiling Contiki for the MSP430.
|
|
|
|
Windows users, see \ref esb-win-setup. FreeBSD users, see \ref esb-freebsd-setup
|
|
|
|
\section esb-win-setup Setting up the Windows environment
|
|
|
|
The Contiki development environment under Windows uses the Cygwin
|
|
environment. Cygwin is a Linux-like environment for Windows. Cygwin
|
|
can be found at http://www.cygwin.com. Click on the icon "Install
|
|
Cygwin Now" to the right to get the installation started.
|
|
|
|
Choose "Install from Internet" and then specify where you want to
|
|
install cygwin (recommended installation path:
|
|
<tt>C:\\cygwin</tt>). Continue with the installation until you are
|
|
asked to select packages. Most packages can be left as "Default" but
|
|
there is one package that are not installed by default. Install the
|
|
following package by clicking at "Default" until it changes to
|
|
"Install":
|
|
|
|
- Devel - contains things for developers (make, etc).
|
|
|
|
<img src="img/esb/cygwin6b.jpg" align="center">
|
|
|
|
When cygwin is installed there should be a cygwin icon that starts
|
|
up a cygwin bash when clicked on. Whenever it is time to compile and
|
|
send programs to the ESB nodes it will be done from a cygwin shell.
|
|
|
|
\subsection winintro-installing-editor C programming editor
|
|
|
|
If you do not already have a nice programming editor it is a good
|
|
idea to download and install one. The Crimson editor is a nice
|
|
windows based editor that is both easy to get started with and
|
|
fairly powerful.
|
|
|
|
Crimson Editor can be found at:
|
|
http://www.crimsoneditor.com/
|
|
|
|
The editor is useful both when editing C programs and when
|
|
modifying scripts and configuration files.
|
|
|
|
\subsection winintro-installing-compiler MSP430 Compiler and tools
|
|
|
|
A compiler is needed to compile the programs to the MSP430
|
|
microprocessor that is used on the ESB sensor nodes. Download and
|
|
install the GCC toolchain for MSP430 (recommended installation path:
|
|
C:\\MSP430\\).
|
|
|
|
The GCC toolchain for MSP430 can be found at:
|
|
http://sourceforge.net/projects/mspgcc/
|
|
|
|
When the above software is installed you also need to set-up the
|
|
PATH so that all of the necessary tools can be reached. In cygwin
|
|
this is done by the following line (given that you have installed
|
|
at recommended locations):
|
|
|
|
<tt>
|
|
export PATH=\$PATH:/cygdrive/c/MSP430/mspgcc/bin
|
|
</tt>
|
|
|
|
This line can also be added to the .profile startup file in your cygwin
|
|
home directory
|
|
(<tt>C:\\cygwin\\home\\\<YOUR USERNAME\>\\.profile</tt>).
|
|
|
|
If your home directory is located elsewhere you can find it by
|
|
starting cygwin and running \c cd followed by \c pwd.
|
|
|
|
\subsection winintro-installing-contiki The Contiki operating system, including examples
|
|
|
|
When programming the ESB sensor nodes it is very useful to have an
|
|
operating system that takes care of some of the low-level tasks and
|
|
also gives you as a programmer APIs for things like events, hardware
|
|
and networking. We will use the Contiki operating system developed by
|
|
Adam Dunkels, SICS, which is very well suited when programming small
|
|
embedded systems.
|
|
|
|
The Contiki OS can be found at:
|
|
http://www.sics.se/~adam/contiki/
|
|
|
|
Unzip the Contiki OS at (for example) C:\\
|
|
and you will get the following directories among others:
|
|
|
|
- contiki-2.x/core - the contiki operating system
|
|
- contiki-2.x/platform/esb - the contiki operating system drivers, etc for the ESB
|
|
- contiki-2.x/platform/esb/apps/ - example applications for the ESB
|
|
|
|
\subsection winintro-testing Testing the tools
|
|
|
|
Now everything necessary to start developing Contiki-based sensor net
|
|
applications should be installed. Start cygwin and change to the
|
|
directory <tt>contiki-2.x/platform/esb/</tt>. Then call <tt>make
|
|
beeper.co</tt>.
|
|
|
|
If you get an error about multiple cygwin dlls when compiling, you
|
|
need to delete <tt>cygwin1.dll</tt> from the MSP430 GCC toolchain
|
|
(<tt>C:\\MSP430\\bin\\cygwin1.dll</tt>).
|
|
|
|
Connect a node and turn it on. Upload the test application by calling
|
|
<tt>make beeper.u</tt>.
|
|
|
|
\subsection winintro-testing-development Development tools
|
|
|
|
- <tt>make \<SPEC\></tt> will compile and make a executable file ready
|
|
for sending to the ESB nodes. Depending on the \c SPEC it might even
|
|
startup the application that sends the executable to the
|
|
node. Typically you would write things like <tt>"make beeper.u"</tt>
|
|
to get the file <tt>beeper.c</tt> compiled, linked and sent out to the
|
|
ESB node
|
|
|
|
\subsection winintro-testing-shell Some basic shell commands
|
|
|
|
- <tt> cd \<DIR\></tt> change to a specified directory (same as in DOS)
|
|
- <tt> pwd \<DIR\></tt> shows your current directory
|
|
- <tt> ls</tt> list the directory
|
|
- <tt> mkdir \<DIR\></tt> creates a new directory
|
|
- <tt> cp \<SRC\> \<DEST\></tt> copies a file
|
|
|
|
\section esb-freebsd-setup Setting up the FreeBSD environment
|
|
|
|
Download the msp430-gcc, msp430-binutils, and
|
|
msp430-libc packages from
|
|
http://www.sics.se/~adam/contiki/freebsd-packages/. Install the
|
|
packages (as root) with <tt>pkg_add</tt>.
|
|
|
|
\section esb-test-compilation Compiling your first Contiki system
|
|
|
|
\section esb-burn-node-id Burning node IDs to EEPRMOM
|
|
|
|
The Contiki ESB port comes with a small program, <tt>burn-nodeid</tt>
|
|
that semi-permanently stores a (unique) node ID number in the ESB
|
|
EEPROM. When the Contiki ESB port boots up, this node ID is restored
|
|
from the EEPROM. To compile and run this program, go into your project
|
|
directory and run
|
|
|
|
<tt>make burn-nodeid.u nodeid=X</tt>
|
|
|
|
Where <tt>X</tt> is the node ID that will be burned into EEPROM. The
|
|
<tt>burn-nodeid</tt> program stores the node ID in EEPROM, reads it
|
|
back, and writes the output
