\section{Introduction}
CanFestival is an OpenSource (LGPL and GPL) \canopen{} framework.
\subsection{The CanFestival project}
This project, initiated by Edouard TISSERANT in 2001, has grown thanks to
Francis DUPIN and other contributors.
Today, CanFestival focuses on providing an ANSI{}-C platform independent
\canopen{} stack that can be implemented as master or slave nodes on PCs,
Real{}-time IPCs, and Microcontrollers.
CanFestival is a project supported by Lolitech.
\subsection{What is \canopen{}}
CANopen is a CAN based high level protocol. It defines some protocols to
:
\liststyleLi
\begin{enumerate}
\item Configure a CAN network.
\item Transmit data to a specific node or in broadcast.
\item Administrate the network. For example detecting a not responding
node.
\end{enumerate}
The documentation can be found on the CAN in Automation website :
\href{http://www.can-cia.de/canopen}{http://www.can{}-cia.de/canopen}
The most important document about \canopen{} is the normative CiA Draft
Standard 301, version 4.02. You can now download the specification from the
CAN in Automation website at no cost.
To continue reading this document, let us assume that you have read some
papers introducing \canopen{}.
\section{CanFestival Features}
\subsection{Tools }
The \canopen{} library is coming with some tools :
\liststyleLii
\begin{enumerate}
\item Object Dictionary editor GUI. WxPython Model{}-View{}-Controler
based GUI, that help a lot in generating object dictionary source code
for each node.
\item A configure script, that let you chose compile time options such
as target CPU/HOST, CAN and TIMER drivers.\newline
This script has not been generated with autoconf, it has been made
keeping micro{}-controller target in mind.
\end{enumerate}
\subsection{Standard conformance}
\paragraph{Multi{}-Platform}
\liststyleLiii
\begin{enumerate}
\item Library source code is C{}-ANSI.
\item Driver and examples coding conventions merely depend on target
specific contributor/compiler.
\item Unix compatible interfaces and examples should compile and run on
any Unix system (tested on GNU/Linux and GNU/FreeBSD).
\end{enumerate}

\end{center}
\bigskip
\subsection{CanFestival CAN interfaces}
Because most CAN controllers and drivers implement FIFOs, CanFestival
consider sending message as a non bloking operation.
In order to prevent reentrent calls to the stack, messages reception is
implemented differently on {\textmu}C and OS.:
\liststyleLvi
\begin{enumerate}
\item {\textmu}C must provide interuption masking for timer and can
receive TI\newline
\begin{center}
\includegraphics[width=12cm]{Pictures/10000201000003CA0000016604E6A5EF.png}
\end{center}
\item OS must provide a receive thread, a timer thread and a mutex. CAN
reception is a bloking operation.\newline
\begin{center}
\includegraphics[width=12cm]{Pictures/10000201000003F9000002CF8B0CDAEA.png}
\end{center}
\end{enumerate}
\subsection{CanFestival events scheduling}
A \canopen{} node must be able to take delayed actions.
As exemples, periodic sync emission, heartbeat production or SDO timeout
need to set some alarms that will be called later and do the job.
{\textmu}C generaly do not have enough free timers to handle all the
\canopen{} needs directly. Moreover, CanFestival internal data may be
corrupt by reentrant calls.
CanFestival implement a micro{}-scheduler (timer.c). It uses only one
timer to mimic many timers. It manage an alarm table, and call alarms
at desired time.
\begin{center}
\includegraphics[width=12cm]{Pictures/100000000000022C000000DEDAD2140C.png}
\end{center}
Scheduler can handle short clock value ranges limitation found on some
{\textmu}C. As an example, value range for a 16bit clock counter with
4{\textmu}s tick is crossed within 0.26 seconds... Long alarms must be
segmented.
Chronogram illustrate a long alarm (A) and a short periodic alarm (B),
with a A value {\textgreater} clock range {\textgreater} B value.
Values t0...t8 are successive setTimer call parameter values. t1
illustrates an intermediate call to TimeDispatch, caused by a delay
longer than clock range. Because of long alarm segmentation, at the end
of t1, TimeDispatch call will not trig any alarm callback.
\begin{center}
\includegraphics[width=12cm]{Pictures/1000000000000396000000FFC42573DA.png}
\end{center}
\section{Linux Target}
Linux target is default configure target.
\subsection{Linux Compilation and installation}
Call ./configure {--}help to see all available compile time options.
After invoking ./configure with your platform specific switches, just
type make.
{\ttfamily
./configure [options]}
{\ttfamily
make}
{\ttfamily
make install}
\subsubsection{Standard Linux node}
Configure switch:
{\ttfamily
{}-{}-timers=unix}
To do a \canopen{} node running on PC{}-Linux, you need :
\liststyleLvii
\begin{enumerate}
\item A working linux distribution
\item One or more Peak system PC CAN interface and the last Peak Linux
driver installed.
\end{enumerate}
\subsubsection{Real{}-Time Linux node}
Configure switch:
{\ttfamily
{}-{}-timers=xeno}
To do a \canopen{} node running on PC{}-Linux, you need :
\liststyleLviii
\begin{enumerate}
\item A working Linux distribution patched with XENOMAI 2.1 or greater.
\item One or more Peak system PC CAN interface and the last Peak Real
Time Linux driver installed.
\end{enumerate}
\subsubsection{Linux kernel node}
To do a CANopen node running on PC-Linux in kernel space, you need:
\paragraph{A working Linux distribution with pre-built 2.6.x.x kernel sources}
\paragraph{A CAN card driver compatible with CanFestival}
\subsubsection{CAN devices}
Curently supported CAN devices and corresponding configure switch:
\paragraph{Peak systems}
Configure switch:
{\ttfamily
{}-{}-can=peak\_linux}
PeakSystems CAN interface is automatically chosen as default CAN
interface if libpcan is present in the system.
Please download driver at
\href{http://www.peak-system.com/linux}{http://www.peak{}-system.com/linux}
and follow instructions in order to install driver on your system.
\paragraph{Socket{}-Can (http://socketcan.berlios.de)}
Configure switch:
{\ttfamily
{}-{}-can=socket}
\paragraph{LinCan}
Configure switch:
{\ttfamily
{}-{}-can=lincan}
\paragraph{Virtual CAN interfaces (for test/debug)}
Configure switch:
{\ttfamily
{}-{}-can=virtual (in user space)}
{\ttfamily
{}-{}-can=virtual\_kernel (in kernel space)}
Virtual CAN interface use Unix pipes to emulate a virtual CAN network.
Each message issued from a node is repeat to all other nodes. Currently
only works with nodes running in the same process, and does not support
work with Xenomai.
\subsection{Testing your CanFestival installation}
Sample provided in /example/TestMasterSlave is installed into your
system during installation.
{\ttfamily
TestMasterSlave}
Default CAN driver library is libcanfestival\_can\_virtual.so., which
will simply pass CAN messages through Unix pipes between Master and
Slave.
You may also want to specify different can interface and define some CAN
ports. Another example using Peak{\textquotesingle}s dual PCMCIA
(configure and install with {--}can=peak) :
{\ttfamily
TestMasterSlave {}-l libcanfestival\_can\_peak.so {}-s 40 {}-m 41}
{\ttfamily
example/kerneltest}
It's based on TestMasterSlave example and has the same functionality. Uses virtual can driver as default too. After successfull installation you can insert the module by typing:
modprobe canf\_ktest
Module control is done by simple console 'canf\_ktest\_console' which is used to start/stop sending data.
\section{Windows Targets}
CanFestival can be compiled and run on Windows platform. It is possible
to use both Cygwin and win32 native runtime environment.
\subsection{Object Dictionary Editor GUI installation.}
Please refer to
\hyperlink{a821UsingDictionaryEditorGUIoutline}{8.2.1)Using Dictionary
Editor GUI}
\subsection{CYGWIN}
\subsubsection{Requirements}
Cygwin have to be installed with those packages :
\liststyleLix
\begin{enumerate}
\item gcc
\item unzip
\item wget
\item make
\end{enumerate}
Currently, the only supported CAN devices are PeakSystems ones, with
PcanLight driver and library.
Please download driver at
\href{http://www.peak-system.com/themen/download_gb.html}{http://www.peak{}-system.com/themen/download\_gb.html}
\space and follow instructions in order to install driver on your system.
Install Cygwin as required, and the driver for your Peak CAN device.
Open a Cygwin terminal, and follow those instructions:
\subsubsection{Cygwin configuration and compilation}
\paragraph{A single node with PcanLight and Peak CAN{}-USB adapter}
Download the PCAN{}-Light Zip file for your HW ( URL from download page
):
{\ttfamily
wget http://www.peak{}-system.com/files/usb.zip}
Extract its content into your cygwin home (it will create a ``Disk''
directory):
{\ttfamily
unzip usb.zip}
Configure CanFestival3 providing path to the desired PcanLight
implementation:
{\ttfamily
cd CanFestival{}-3}
{\ttfamily
export PCAN\_INCLUDE=\~{}/Disk/PCAN{}-Light/Api/}
{\ttfamily
export PCAN\_HEADER=Pcan\_usb.h}
{\ttfamily
export PCAN\_LIB=\~{}/Disk/PCAN{}-Light/Lib/Visual{\textbackslash}
C++/Pcan\_usb.lib}
{\ttfamily
./configure {}-{--}can=peak\_win32}
{\ttfamily
make}
In order to test, you have to use another CanFestival node, connect with
a CAN cable.
{\ttfamily
cp \~{}/Disk/PCAN{}-Light/Pcan\_usb.dll .}
{\ttfamily
./examples/TestMasterSlave/TestMasterSlave {\textbackslash}}
{\ttfamily
{}-l drivers/can\_peak\_win32/cygcan\_peak\_win32.dll
{\textbackslash}}
{\ttfamily
{}-S 500K {}-M none}
Then, on the other node :
{\ttfamily
./TestMasterSlave {}-l my\_driver.so {}-S none {}-M 500K}
Now messages are beeing exchanged between master and slave node.
\paragraph{Two nodes with PcanLight and Peak dual PCMCIA{}-CAN adapter}
Download the PCAN{}-Light Zip file for your HW ( URL from download page
):
{\ttfamily
wget http://www.peak{}-system.com/files/pccard.zip}
Extract its content into your cygwin home (it will create a ``Disk''
directory):
{\ttfamily
unzip pccard.zip}
The configure CanFestival3 providing path to the desired PcanLight
implementation:
{\ttfamily
export PCAN\_INCLUDE=\~{}/Disk/PCAN{}-Light/Api/\newline
export PCAN\_HEADER=Pcan\_pcc.h\newline
export PCAN\_LIB=\~{}/Disk/PCAN{}-Light/Lib/Visual{\textbackslash}
C++/Pcan\_pcc.lib\newline
export PCAN2\_HEADER=Pcan\_2pcc.\newline
export PCAN2\_LIB=\~{}/Disk/PCAN{}-Light/Lib/Visual{\textbackslash}
C++/Pcan\_2pcc.lib}
In order to test, just connect together both CAN ports of the PCMCIA
card. Don{\textquotesingle}t forget 120ohms terminator.
{\ttfamily
cp \~{}/Disk/PCAN{}-Light/Pcan\_pcc.dll .}
{\ttfamily
cp \~{}/Disk/PCAN{}-Light/Pcan\_2pcc.dll .}
{\ttfamily
./examples/TestMasterSlave/TestMasterSlave {\textbackslash}}
{\ttfamily
{}-l drivers/can\_peak\_win32/cygcan\_peak\_win32.dll}
Messages are then exchanged between master and slave node, both inside
TestMasterSlave{\textquotesingle}s process.
\subsection{Visual Studio C++}
\subsubsection{Requirements}
Minimal Cygwin installation is required at configuration time in order
to create specific header files (config.h and cancfg.h). Once this
files created, cygwin is not necessary any more.
Project and solution files have been created and tested with Visual
Studio Express 2005. Be sure to have installed Microsoft Platform SDK,
as recommended at the end of Visual Studio installation.
\subsubsection{Configuration with cygwin}
Follow instructions given at
\hyperlink{Cygwin configuration and compilation}{Cygwin
configuration and compilation}, but do neither call make nor do tests,
just do configuration steps. This will create headers files accordingly
to your configuration parameters, and the desired CAN hardware.
\subsubsection{Compilation with Visual Studio}
You can either load independents ``*.vcproj'' project files along your
own projects in your own solution or load the provided
``CanFestival{}-3.vc8.sln'' solution files directly.
Build CanFestival{}-3 project first.
\paragraph{PcanLight and the can\_peak\_win32 project.}
Chosen Pcan\_xxx.lib and eventually Pcan\_2xxx.lib files must be added
to can\_peak\_win32 \space \space project before build of the DLL.
\subsubsection{Testing}
Copy eventually needed dlls (ie : Pcan\_Nxxx.lib) into Release or Debug
directory, and run the test program:
{\ttfamily
TestMasterSlave.exe {}-l can\_peak\_win32.dll}
\subsection{MSYS}
\subsubsection{Requirements}
Download from : http://sourceforge.net/project/showfiles.php?group\_id=2435
\begin{enumerate}
\item MSYS-1.0.10.exe
\item MinGW-5.1.3.exe
\item mingwPORT (which contains wget-1.9.1)
\end{enumerate}
Please download driver at http://www.peak-system.com/themen/download\_gb.html
and follow instructions in order to install driver on your system.
Install MSYS and MingW as required, and the driver for your Peak CAN
device. Open a MSYS terminal, and follow those instructions:\\
\begin{itemize}
\item extract wget-1.9.1-mingwPORT.tar.bz2
\item copy wget.exe in c:\textbackslash{}msys\textbackslash{}1.0\textbackslash{}bin\textbackslash{}
\item start MSYS and check the file /etc/fstab contain the line c:/MinGW
/mingw
\end{itemize}
\subsubsection{MSYS configuration and compilation}
Instructions for compilation are nearly the same as CYGWIN part.
\paragraph{A single node with PcanLight and Peak CAN-USB adapter}
Download the PCAN-Light Zip file for your HW ( URL from download page
):
\texttt{wget http://www.peak-system.com/files/usb.zip}~\\
Extract its content into your MSYS's home (it will create a \char`\"{}Disk\char`\"{}
directory):
\texttt{unzip usb.zip}~\\
Configure CanFestival3 providing path to the desired PcanLight implementation:
\texttt{cd CanFestival-3}
\texttt{export PCAN\_INCLUDE=\~{ }/Disk/PCAN-Light/Api/}
\texttt{export PCAN\_HEADER=Pcan\_usb.h}
\texttt{export PCAN\_LIB=\~{ }/Disk/PCAN-Light/Lib/Visual\textbackslash{}
C++/Pcan\_usb.lib}
\texttt{./configure -{}-can=peak\_win32}
\texttt{make}~\\
In order to test, you have to use another CanFestival node, connect
with a CAN cable.
\texttt{cp \~{ }/Disk/PCAN-Light/Pcan\_usb.dll .}
\texttt{./examples/TestMasterSlave/TestMasterSlave \textbackslash{}}
\texttt{-l drivers/can\_peak\_win32/cygcan\_peak\_win32.dll \textbackslash{}}
\texttt{-S 500K -M none}~\\
Then, on the other node :
\texttt{./TestMasterSlave -l my\_driver.so -S none -M 500K -m 0}
Now messages are beeing exchanged between master and slave node.
\paragraph{Two nodes with PcanLight and Peak dual PCMCIA-CAN adapter}
Download the PCAN-Light Zip file for your HW ( URL from download page
):
\texttt{wget http://www.peak-system.com/files/pccard.zip}~\\
\\
Extract its content into your MSYS's home (it will create a \char`\"{}Disk\char`\"{}
directory):
\texttt{unzip pccard.zip}~\\
\\
The configure CanFestival3 providing path to the desired PcanLight
implementation:\\
\texttt{export PCAN\_INCLUDE=\~{ }/Disk/PCAN-Light/Api/}
\texttt{export PCAN\_HEADER=Pcan\_pcc.h}
\texttt{export PCAN\_LIB=\~{ }/Disk/PCAN-Light/Lib/Visual\textbackslash{}
C++/Pcan\_pcc.lib}
\texttt{export PCAN2\_HEADER=Pcan\_2pcc.h}
\texttt{export PCAN2\_LIB=\~{ }/Disk/PCAN-Light/Lib/Visual\textbackslash{}
C++/Pcan\_2pcc.lib}~\\
In order to test, just connect together both CAN ports of the PCMCIA
card. Don't forget 120ohms terminator.
\texttt{cp\~{ }/Disk/PCAN-Light/Pcan\_pcc.dll ~.}
\texttt{cp \~{ }/Disk/PCAN-Light/Pcan\_2pcc.dll ~.}
\texttt{./examples/TestMasterSlave/TestMasterSlave \textbackslash{}}
\texttt{-l drivers/can\_peak\_win32/cygcan\_peak\_win32.dll -m 0 -s
1}~\\
Messages are then exchanged between master and slave node, both inside
TestMasterSlave's process.
\section{Motorola HCS12}
The examples have been tested on a MC9S12DG255 mounted on a
Elektronikladen HCS12 T{}-board.
Beware that there are few differences in the MSCAN module of the
68HC12 and HCS12 microcontroller. For a HC12, you must adapt the driver
that we provide for \space the HCS12.
For the difference MSCAN HC12/HCS12, see the Motorola application note
AN2011/D.
Configure switch:
{\ttfamily
{}-{}-target=hcs12}
To do a \canopen{} node running on a microncontroller Motorola MC9S12DP256,
you need :
\liststyleLx
\begin{enumerate}
\item The compiler GNU gcc for HC11, HC12, HCS12 : m6811{}-elf. \newline
Download the \textbf{release 3.1} at :
\space \href{http://m68hc11.serveftp.org/m68hc11_pkg_rpm.php}{http://m68hc11.serveftp.org/m68hc11\_pkg\_rpm.php}
\item A board with this chip. We are using the T{}-board from
Electronikladden.
\item At least about 40 kBytes of program memory.
\item A tool to flash the memory. (We are using the hight cost
Lauterbach debugger).
\end{enumerate}
\subsection{Running a HCS12 node}
\subsubsection{Compiling Canfestival:}
{\ttfamily
./configure {--}target=hcs12}
\subsubsection{Compiling and building an example}
Enter in the folder of an HCS12 example,
{\ttfamily
make all}
\subsubsection{Flashing the memory :}
Use your prefered loader ! If you are using a debugger Lauterbach, you
can load the bash file : trace32\_flash\_programmer.cmm. It loads
directly the elf file.
\subsubsection{Connecting to a serial RS232 console :}
Connect the portS(TxD0) of the HCS12 to a console configured at 19200
bauds 8N1, via a Max232 chip to adapt the electricals levels. On Linux,
you can use minicom. Connecting to a console is usefull to read the
messages, but not required.
\subsubsection{Connecting to the CAN network :}
Connect the port CAN0 (pin PM0, PM1) to the network via a CAN
controller. On our board, the CAN controler is a PCA82C250 chip.
\subsubsection{starting the node :}
Press the reset of your HCS12 board.

Notes for Concise DCF :}
\bigskip
{\sffamily
In this example, Master configure \space heartbeat producer time at 1000 ms
for slave node{}-id 0x02 by concise DCF according DS{}-302 profile. }
{\sffamily
}
{\sffamily
Index 0x1F22 , sub{}-index 0x00 of the master OD, correspond to the
number of entries. This equal to the maximum possible nodeId (127).
Each sub{}-index points to the Node{}-ID of the device, to which the
configuration belongs. }
\bigskip
{\sffamily
To add more parameters configurations to the slave, the value at
sub{}-index 0x02 must be a binary stream (little{}-endian) following
this structure :\newline
\{
(UNS32) nb of entries\newline
(UNS16) index parameter 1\newline
(UNS8) sub{}-index parameter 1\newline
(UNS32) size data parameter 1\newline
(DOMAIN) data parameter 1\newline
(UNS16) index parameter 2\newline
(UNS8) sub{}-index parameter 2\newline
(UNS32) size data parameter 2\newline
(DOMAIN) data parameter 2\newline
\space \space \space \space \space ....\newline
(UNS16) index parameter n\newline
(UNS8) sub{}-index parameter n\newline
(UNS32) size data parameter n\newline
(DOMAIN) data parameter n\newline
\}
}
{\sffamily
So the binary value stream to configure heartbeat producer time must be
:\newline
0100000017100002000000e803}
{\sffamily
The slave node is configured just before the Master entering in
Pre\_operational state.}
\subsection{gene\_SYNC\_HCS12 :}
This is a simple \canopen{} node that only send cyclic SYNC message. It
demonstrate implementation on HCS12 based board.
\bigskip
\subsection{kerneltest :}
Example based on TestMasterSlave slightly modified to suit kernel space requisites. It will do the same as TestMasterSlave but in kernel space sending kernel messages (displayed by dmesg for example). It is designed as external kernel module implemented as character device. There is a shell script called 'insert.sh', which will insert the module and create a new device file /dev/canf\_ktest (used to sending commands to module). To actual sending commands you can use simple console named 'canf\_ktest\_console'.
The module is dependent on a another separate module 'canfestival.ko' implementing CanOpen stack which exports requisite functions. Canfestival.ko module is then dependent on CAN card driver module, by default CAN virtual driver will be loaded. After installing modules (make install), all dependencies are solved automatically by kernel.
To run the example type:
{\ttfamily
sh run.sh}
It will insert required modules, start console, and after quitting console it'll remove modules from kernel.

\section{Developing a new node}
Using provided examples as a base for your new node is generally a good
idea. You can also use the provided *.od files as a base for your node
object dictionary.
Creating a new \canopen{} node implies to define the Object Dictionary of
this node. For that, developer has to provide a C file. This C file
contains the definition of all dictionary entries, and some kind of
index table that helps the stack to access some entries directly.
\subsection{Using Dictionary Editor GUI}
The Object Dictionary Editor is a WxPython based GUI that is used to
create the C file needed to create a new \canopen{} node.
\subsubsection{Installation and usage on Linux}
You first have to download and install Gnosis XML modules. This is
automated by a Makefile rule.
{\ttfamily
cd objdictgen}
{\ttfamily
make}
Now start the editor.
{\ttfamily
python objdictedit.py [od files...]}
\subsubsection{Installation and usage on Windows}
Install Python (at least version 2.4) and wxPython (at least version
2.6.3.2).
Cygwin users can install Gnosis XML utils the same as Linux use. Just
call make.
{\ttfamily
cd objdictgen}
{\ttfamily
make}
Others will have to download and intall Gnosis XML by hand :
{\ttfamily
Gnosis Utils:}
{\ttfamily
http://freshmeat.net/projects/gnosisxml/}
{\ttfamily
http://www.gnosis.cx/download/Gnosis\_Utils.More/Gnosis\_Utils{}-1.2.1.win32{}-py24.exe}
{\ttfamily
Get latest version.}
Download CanFestival archive and uncompress it. Use windows file
explorer to go into CanFestival3{\textbackslash}objdicgten, and
double{}-click on objdictedit.py.
\subsubsection{About}
The Object Dictionary editor GUI is a python application that use the
Model{}-View{}-Controller design pattern. It depends on WxPython to
display view on any supported platform.

\subsection{Generating the object Dictionary}
Once object dictionary has been edited and saved, you have to generate
object dictionary C code for your CanFestival node.
\subsubsection{With GUI}
Menu entry ``File/Build Dictionary''.
\begin{center}
\includegraphics[width=4cm]{Pictures/10000201000000B7000000C66AF89CD5.png}

\section{FAQ}
\subsection{General}
\subsubsection{Does the code compiles on Windows ?}
Yes, with both Cygwin and Visual Studio C++.
Because \canopen{} layer is coded with C, put a compilation option /TC or
/TP if you plan to mix C++ files. See the MSDN documentation about
that.
\subsubsection{How to fit the library to an other microcontr\^oler ?}
First, be sure that you have at least 40K bytes of program memory, and
about 2k of RAM.
You have to create target specific interface to HW resources. Take model
on bundled interfaces provided in drivers/ and create your own
interface. You also have to update Makefile.in files for target
specific cflags and options. Choose {--}target= configure switch to
compile your specific interface.
You are welcome to contribute{}-back your own interfaces! Other
Canfestival users will use it and provide feedback, tests and
enhancements.
\subsubsection{Is CanFestival3 conform to DS301 v.4.02 ?}
Thanks to Philippe Foureys (IUT of Valence), a slave node have been
tested with the National Instrument \canopen{} Conformance Test. It passed
the test with success.
Some very small unconformity have been found in very unusual situations,
for example in the SDO code response to wrong messages.
\subsection{LINUX}
\subsubsection{How to use a Peaksystem CAN board ?}
Just install peak driver and then compile and install Canfestival. Peak
driver is detected at compile time.
\subsubsection{How to use an unsupported CAN board ?}
You have to install the specific driver on your system, with necessary
libs and headers.
Use can\_peak.c/h or can\_virtual.c/h as an example, and adapt it to
your driver API.
Execute configure script and choose {}-{}-can=mydriver
\subsection{Win32}
Compatibility:
\liststyleLxi
\begin{enumerate}
\item Code was compiled MS VisualStudio 2003.NET and VisualStudio
2005.NET for WindowsXP \space with ANSI and UNICODE configurations and for
WindowsCE 5.0.
\item Some preliminary testing was done, but not enough to be used in
mission critical projects.
\end{enumerate}
Additional Features:
\liststyleLxii
\begin{enumerate}
\item Non{}-integral integers support implementation UNS24, UNS40, UNS48
etc.
\item When enable debug output with DEBUG\_WAR\_CONSOLE\_ON or
DEBUG\_ERR\_CONSOLE\_ON, you can navigate in CanFestival source code by
double clicking at diagnostic lines in VisualStudio.NET 200X Debug
Output Window.
\end{enumerate}
Custom size integral types such as INTEGER24, UNS40, INTEGER56 etc. have
been defined as 64 bits integers. You will need to replace sizeof(TYPE)
operators to sizeof\_TYPE definitions in generated code, i.e. replace
sizeof(UNS40) with sizeof\_UNS40.
\bigskip
\subsection{HCS12}
\subsubsection{Which board are you using ?}
A T{}-board from elektronikladen with a MC9S12DP256 or MC9S12DG256.
\subsubsection{Does the code compile with an other compiler than GNU gcc
?}
It is known to work with Metrowerks CodeWarrior. Here are some tips from
Philippe Foureys. :
\paragraph{Interrupt functions}
\subparagraph{Code for GCC:}
{\ttfamily
// prototype\newline
void \_\_attribute\_\_((interrupt))timer3Hdl(void):\newline
// function\newline
void \_\_attribute\_\_((interrupt))timer3Hdl(void)\{...\}}
\subparagraph{Code for CodeWarrior}

\subsubsection{Does the code works in banked memory ?}
No. Today it seems that the port of gcc is bogged for using the banked
memory. So, unfortunately, we are limited to 48 Kbytes of memory code.
\subsubsection{What GCC version are you using ?}
We are using the stable RPM release 2.2 :
\liststyleLxiii
\begin{enumerate}
\item GNU Gcc 3.0.4. Build 20030501
\item Newlib 1.10.0 Build 20030421
\item GNU Binutils 2.12.1 Build 20030427
\end{enumerate}
