\section{Introduction} |
393 | 39 |
|
40 |
CanFestival is an OpenSource (LGPL and GPL) \canopen framework. |
|
208 | 41 |
|
42 |
\subsection{The CanFestival project} |
|
393 | 43 |
|
44 |
This project, initiated by Edouard TISSERANT in 2001, has grown thanks |
|
45 |
to Francis DUPIN and other contributors. |
|
46 |
||
47 |
Today, CanFestival focuses on providing an ANSI-C platform independent |
|
48 |
\canopen stack that can be implemented as master or slave nodes on |
|
49 |
PCs, Real-time IPCs, and Microcontrollers. |
|
208 | 50 |
|
51 |
CanFestival is a project supported by Lolitech. |
|
52 |
||
393 | 53 |
|
54 |
\subsection{What is \canopen} |
|
55 |
||
56 |
CANopen is a CAN based high level protocol. It defines some protocols |
|
57 |
to : |
|
58 |
||
208 | 59 |
\begin{enumerate} |
393 | 60 |
\item Configure a CAN network. |
61 |
\item Transmit data to a specific node or in broadcast. |
|
62 |
\item Administrate the network. For example detecting a not responding node. |
|
208 | 63 |
\end{enumerate} |

64 |
The documentation can be found on the CAN in Automation website : |
208 | 65 |
|
393 | 66 |
\href{http://www.can-cia.de/canopen}{http://www.can-cia.de/canopen} |
67 |
||
68 |
The most important document about \canopen is the normative CiA Draft |
|
69 |
Standard 301, version 4.02. You can now download the specification |
|
70 |
from the CAN in Automation website at no cost. |
|
71 |
||
72 |
To continue reading this document, let us assume that you have read |
|
73 |
some papers introducing \canopen . |
|

\subsection{Tools } |
393 | 80 |
|
81 |
The \canopen library is coming with some tools : |
|
82 |
||
208 | 83 |
\begin{enumerate} |
393 | 84 |
\item Object Dictionary editor GUI. WxPython Model-View-Controler based |

|
85 |
GUI, that helps a lot in generating object dictionary source code for |
393 | 86 |
each node. |
87 |
\item A configure script, that let you chose compile time options such as |
|
88 |
target CPU/HOST, CAN and TIMER drivers.\\ |
|
89 |
This script has not been generated with autoconf, it has been made |
|
90 |
keeping micro-controller target in mind. |
|
208 | 91 |

\subsection{Multi-Platform} |
393 | 94 |
|
208 | 95 |
\begin{enumerate} |
393 | 96 |
\item Library source code is C-ANSI. |
97 |
\item Driver and examples coding conventions merely depend on target specific |
|
98 |
contributor/compiler. |
|
208 | 99 |
\item Unix compatible interfaces and examples should compile and run on |
393 | 100 |
any Unix system (tested on GNU/Linux and GNU/FreeBSD). |
208 | 101 |

{\textmu}C generally do not have enough free timers to handle all |
393 | 262 |
the \canopen needs directly. Moreover, CanFestival internal data |
263 |
may be corrupt by reentrant calls. |
|
264 |
||
265 |
CanFestival implement a micro -scheduler (timer.c). It uses only one |
|
208 | 266 |
timer to mimic many timers. It manage an alarm table, and call alarms |
267 |
at desired time. |

||
273 |
Scheduler can handle short clock value ranges limitation found on |
|
274 |
some {\textmu}C. As an example, value range for a 16bit clock counter |
|
275 |
with 4{\textmu}s tick is crossed within 0.26 seconds... Long alarms |
|
276 |
must be segmented. |
|
277 |
||
278 |
Chronogram illustrate a long alarm (A) and a short periodic alarm |
|
279 |
(B), with a A value {\textgreater} clock range {\textgreater} |
|
280 |
B value. Values t0...t8 are successive setTimer call parameter values. |
|
281 |
t1 illustrates an intermediate call to TimeDispatch, caused by a delay |
|
282 |
longer than clock range. Because of long alarm segmentation, at the |
|
283 |
end of t1, TimeDispatch call will not trig any alarm callback. |

Default CAN driver library is libcanfestival\_can\_virtual.so., which |
208 | 439 |
will simply pass CAN messages through Unix pipes between Master and |
393 | 440 |
Slave. |
441 |
||
442 |
You may also want to specify different can interface and define some |
|
443 |
CAN ports. Another example using Peak{\textquotesingle}s dual PCMCIA |

\subsubsection{Requirements} |
393 | 610 |
|
208 | 611 |
Minimal Cygwin installation is required at configuration time in order |
612 |
to create specific header files (config.h and cancfg.h). Once this |
|
613 |
files created, cygwin is not necessary any more. |
|
614 |
||
615 |
Project and solution files have been created and tested with Visual |
|
393 | 616 |
Studio Express 2005. Be sure to have installed Microsoft Platform |
617 |
SDK, as recommended at the end of Visual Studio installation. |
|
618 |
||
208 | 619 |
|
620 |
\subsubsection{Configuration with cygwin} |
|
393 | 621 |
|
622 |
Follow instructions given at \hyperlink{Cygwin configuration and compilation}{Cygwin |
|
208 | 623 |
configuration and compilation}, but do neither call make nor do tests, |
624 |
just do configuration steps. This will create headers files accordingly |
|
625 |
to your configuration parameters, and the desired CAN hardware. |
|

Example based on TestMasterSlave slightly modified to suit kernel |
943 |
space requisites. It will do the same as TestMasterSlave but in kernel |
|
944 |
space sending kernel messages (displayed by dmesg for example). It |
|
945 |
is designed as external kernel module implemented as character device. |
|
946 |
There is a shell script called 'insert.sh', which will insert the |
|
947 |
module and create a new device file /dev/canf\_ktest (used to sending |
|
948 |
commands to module). To actual sending commands you can use simple |
|
949 |
console named 'canf\_ktest\_console'. The module is dependent on a |
|
950 |
another separate module 'canfestival.ko' implementing CanOpen stack |
|
951 |
which exports requisite functions. Canfestival.ko module is then dependent |
|
952 |
on CAN card driver module, by default CAN virtual driver will be loaded. |
|
953 |
After installing modules (make install), all dependencies are solved |

\section{Developing a new node} |
|
393 | 1003 |
|
1004 |
Using provided examples as a base for your new node is generally a |
|
1005 |
good idea. You can also use the provided {*}.od files as a base for |
|
1006 |
your node object dictionary. |
|
1007 |
||
1008 |
Creating a new \canopen node implies to define the Object Dictionary |
|
1009 |
of this node. For that, developer has to provide a C file. This C |
|
1010 |
file contains the definition of all dictionary entries, and some kind |
|
1011 |
of index table that helps the stack to access some entries directly. |
|
1012 |
||
208 | 1013 |
|
1014 |
\subsection{Using Dictionary Editor GUI} |
|
393 | 1015 |
|
1016 |
The Object Dictionary Editor is a WxPython based GUI that is used |
|
1017 |
to create the C file needed to create a new \canopen node. |
|
1018 |
||
208 | 1019 |
|
1020 |
\subsubsection{Installation and usage on Linux} |
|
393 | 1021 |

\subsubsection{Does the code compiles on Windows ?} |
393 | 1204 |
|
1205 |
Yes, with both Cygwin and Visual Studio C++. |
|
1206 |
||
1207 |
Because \canopen layer is coded with C, put a compilation option |
|
1208 |
/TC or /TP if you plan to mix C++ files. See the MSDN documentation |
|
1209 |
about that. |

\subsubsection{How to fit the library to an other microcontr�ler ?} |
393 | 1213 |
|
1214 |
First, be sure that you have at least 40K bytes of program memory, |
|
1215 |
and about 2k of RAM. |
|
1216 |
||
1217 |
You have to create target specific interface to HW resources. Take |
|
1218 |
model on bundled interfaces provided in drivers/ and create your own |
|
1219 |
interface. You also have to update Makefile.in files for target specific |
|
1220 |
cflags and options. Choose {--}target= configure switch to compile |
|
1221 |
your specific interface. |
|
1222 |
||
1223 |
You are welcome to contribute -back your own interfaces! Other Canfestival |
|
1224 |
users will use it and provide feedback, tests and enhancements. |
|
1225 |
||
208 | 1226 |
|
1227 |
\subsubsection{Is CanFestival3 conform to DS301 v.4.02 ?} |
|
393 | 1228 |
|
208 | 1229 |
Thanks to Philippe Foureys (IUT of Valence), a slave node have been |
393 | 1230 |
tested with the National Instrument \canopen Conformance Test. It |
1231 |
passed the test with success. |
|
208 | 1232 |
|
1233 |
Some very small unconformity have been found in very unusual situations, |
|
1234 |
for example in the SDO code response to wrong messages. |
|
1235 |

\subsubsection{How to use a Peaksystem CAN board ?} |
393 | 1241 |
|
1242 |
Just install peak driver and then compile and install Canfestival. |
|
1243 |
Peak driver is detected at compile time. |
|
1244 |
||
208 | 1245 |
|
1246 |
\subsubsection{How to use an unsupported CAN board ?} |
|
393 | 1247 |
|
208 | 1248 |
You have to install the specific driver on your system, with necessary |
393 | 1249 |
libs and headers. |
1250 |
||
1251 |
Use can\_peak.c/h or can\_virtual.c/h as an example, and adapt it |
|
1252 |
to your driver API. |
|
1253 |
||
1254 |
Execute configure script and choose --can=mydriver |
|
1255 |

\item Non -integral integers support implementation UNS24, UNS40, UNS48 |
1272 |
etc. |
|
1273 |
\item When enable debug output with DEBUG\_WAR\_CONSOLE\_ON or DEBUG\_ERR\_CONSOLE\_ON, |
|
1274 |
you can navigate in CanFestival source code by double clicking at |
|
1275 |
diagnostic lines in VisualStudio.NET 200X Debug Output Window. |

Custom size integral types such as INTEGER24, UNS40, INTEGER56 etc. |
1278 |
have been defined as 64 bits integers. You will need to replace sizeof(TYPE) |
|
208 | 1279 |
operators to sizeof\_TYPE definitions in generated code, i.e. replace |
1280 |
sizeof(UNS40) with sizeof\_UNS40. |

\subsubsection{Does the code works in banked memory ?} |
|
393 | 1446 |
|
208 | 1447 |
No. Today it seems that the port of gcc is bogged for using the banked |
1448 |
memory. So, unfortunately, we are limited to 48 Kbytes of memory code. |
|
1449 |

393 | 1450 |
|
208 | 1451 |
\subsubsection{What GCC version are you using ?} |
393 | 1452 |
|
208 | 1453 |
We are using the stable RPM release 2.2 : |
1454 |
