1 Linux CAN Driver (LinCAN) version 0.2 snapshot
2 Pavel Pisa <pisa@cmp.felk.cvut.cz>
9 The LinCAN is an implementation of the Linux CAN-bus device driver supporting
10 more CAN controller chips and many CAN interface boards. Its development
11 has long history already. The OCERA version of the driver has new better
12 designed internal structure, adds new features (as support for open by multiple
13 applications, select system call) and other enhancements.
15 The driver consist of four main layers:
16 - chip level manipulation routines
17 - board specific support
19 - user-space API and ABI character device interface
25 The driver originates in The Linux Lab Project
26 http://www.llp.fu-berlin.de/
27 then it has been first rewritten by Arnaud Westenberg
28 http://home.wanadoo.nl/arnaud/
29 now it is developed and maintained as part of OCERA framework
32 I am unable to contact previous maintainer Arnaud Westenberg
33 (arnaud@wanadoo.nl). If you know something about him, I like
38 can-0.7.1 latest driver version version published
41 can-0.7.1-tm5 the enhanced version with better support of
42 SJA1000 PeliCAN mode and CAN Ethernet proxy
43 contributed by Tomasz Motylewski <T.Motylewski@bfad.de>
45 can-0.7.1-pi1 the import and usage of previous version for
46 (Dec 2002) OCERA group purposes
48 can-0.7.1-pi3.4 enhanced version with select support and rewritten
49 (Mar 2003) make system for Linux kernels (2.2.x,2.4.x,2.5.x),
50 interrupts service cleanup and partial redesign
53 lincan-0.2-pre heavily rewritten infrastructure of the driver based
54 (Aug 2003) on atomic slot management of queues
56 The actual version of driver have been latest tested it with
57 - PC104 Advantech PCM3680 dual channel board on 2.4 RT-Linux enabled kernel
58 - PiKRON ISA card on 2.4.and 2.6 Linux kernels
59 - BfaD DIMM PC card on 2.4 RT-Linux enabled kernel
60 - KVASER pcican-q on 2.6 Linux kernel
61 - virtual board tested on all systems as well
62 It takes more time to test it with more cards and polish
63 support for 2.2 and 2.6 kernels, but these should be mainly
64 cosmetic changes (I hope ;-), infrastructure and original
65 support for more than 17 boards with more variants is in.

104 Just type 'make' at the command line and driver module should compile
105 without errors for current running kernel.
107 More information can be found in driver documentation at
108 http://cmp.felk.cvut.cz/~pisa/can/
109 http://cmp.felk.cvut.cz/~pisa/can/lincan-X.Y.pdf
113 Type 'make install'. The driver should be copied into actual kernel version
114 modules directory "/lib/modules/x.y.z/kernel/drivers/char".
119 To load the driver type:
120 # insmod can.o hw='your hardware' irq='irq number' io='io address' <options>
121 Example: # insmod can.o hw=pip5 irq=4 io=0x8000
123 The hw argument can be one of:
124 - pip5, for the pip5 computer by MPL
125 - pip6, for the pip6 computer by MPL
126 - pccan-q, for the PCcan-Q ISA card by KVASER
127 - pccan-f, for the PCcan-F ISA card by KVASER
128 - pccan-s, for the PCcan-S ISA card by KVASER
129 - pccan-d, for the PCcan-D ISA card by KVASER
130 - pcican-q, for the PCIcan-Q PCI card by KVASER (4x SJA1000)
131 - pcican-d, for the PCIcan-Q PCI card by KVASER (2x SJA1000)
132 - pcican-s, for the PCIcan-Q PCI card by KVASER (1x SJA1000)
133 - nsican, for the CAN104 PC/104 card by NSI
134 - cc104, for the CAN104 PC/104 card by Contemporary Controls
135 - aim104, for the AIM104CAN PC/104 card by Arcom Control Systems

138 - m437, for the M436 PC/104 card by SECO
139 - bfadcan for sja1000 CAN embedded card made by BFAD GmbH
140 - pikronisa for ISA memory mapped sja1000 CAN card made by PiKRON Ltd.
141 - template, for yet unsupported hardware (you need to edit src/template.c)
142 - virtual, CAN channel for testing of software and driver without CAN hardware
144 options can be one of:
145 - major=<nr>, major specifies the major number of the driver.
146 - minor=<nr>, you can specify which minor numbers the driver should use for your
148 - extended=[1|0], configures the driver to use extended message format.
149 - pelican=[1|0], configures the driver to set the CAN chips into pelican mode.
150 - baudrate=<nr>, sets the baudrate of the device(s)
151 - clock_freq=<nr>, the frequency of the CAN quartz
152 - stdmask=<nr>, sets the standard mask of the device
153 - extmask=<nr>, sets the extended mask of the device
154 - mo15mask=<nr>, sets the mask for message object 15 (i82527 only)
156 There's still a lot of work to do, have a look at the TODO file for more
