PCAN-Light for LINUX is the easy to use software interface for CAN hardware by PEAK-System.

The PCAN drivers for LINUX work with Kernel versions 2.4 up to 4.x The complete package is distributed under the GPL.

If you have any questions about the drivers please contact us.

There's a single API (Application Programming Interface) for all CAN interfaces. This simplifies the software development. The drivers are designed to work with CAN hardware by PEAK-System and 100 percent compatible hardware by OEM vendors. Take care when using third-party hardware, since the drivers use special functions.

Supported Hardware

If you need technical information about the CAN hardware by PEAK-System go to www.peak-system.com.
If you you have any questions, send an e-mail to our LINUX team: linux@peak-system.com

Interested in CANopen® for LINUX?
We support the CANFestival project: http://canfestival.org. CANFestival is an open source CANopen® framework (GPLv2 & LGPLv2) and works with all CAN interfaces by PEAK-System (LINUX/Xenomai/RTAI/WIN32/Cygwin).

Credits

We would like to thank our main developers Klaus Hitschler and Stéphane Grosjean for their excellent work! Also many thanks for the Socket CAN support and the feedback from Oliver Hartkopp and Wolfgang Grandegger. The Xenomai implementation (support only driver up to Version 6.2) was done by Edouard Tisserant and Laurent Bessard - thanks for the great job.

License Information

The driver is linked inside the kernel. This doesn't matter since the driver is GPL'd. However, if you like to customize the driver and distribute it then you must publish the source code of this modification. If you only use the driver's services from your user program it is the same situation like using kernel provided services from a user program. (Note that the driver's services are only of use through kernel services). It does not matter, if your user program is open or closed source and what licence, however. To ease access to the driver's services PEAK provides a library 'libpcan.so'. This library is LGPL'd and therefore can be linked to even closed source programs without any consequences. But if you modify the library you have to give back this modification to the community if you distribute the modified library.

Note to "pcan" users (versions >= 7.5) who want to migrate to mainline linux-can drivers

If you are using "pcan" Linux driver versions >= 7.5 and if you want to migrate to a new Linux system to take advantages of the new linux-can drivers that are part of Kernels >= 3.4, you MUST first uninstall the "pcan" driver (you'll need to be root):

$ cd peak-linux-driver-7.x
$ make uninstall

Uninstalling the "pcan" driver can be made before or after the system upgrade. You'll need to reboot your system, to have the linux-can drivers automatically loaded by the next system start.

IMPORTANT Note on Kernel Versions 2.6.25 and Up

The CAN Network subsystem PF_CAN (aka SocketCAN) became part of the Mainline Linux Kernel starting with version 2.6.25. For this reason the PEAK driver automatically compiles with the recommended netdev support, when CONFIG_CAN is set in the Kernel configuration (see NET=AUTO_NETDEV_SUPPORT setting in driver/Makefile). The automatic detection can furthermore be changed with NET=NETDEV_SUPPORT (force netdev) or NET=NO_NETDEV_SUPPORT (force chardev). To compile the PEAK Linux driver with the former (default) PEAK chardev interface, please invoke

make clean; make NET=NO_NETDEV_SUPPORT

See the /proc/pcan print:

Attention!
When using the netdev driver interface, the chardev driver test tools ("cat /dev/pcanXX", "receivetest", "transmittest") will not work correctly. Receiving of messages won't be possible - these tools are only for the chardev driver.

Release Version 8.4.0

Driver Download Version 8.4.0 (14.06.2017)

Driver Download Version 8.3 (10.01.2017)

Updates: Support of the new PCAN-USB X6 USB to CAN adapter 64-bit driver supports now 32-bit applications built with 32-bit libpcan ($ make -C lib all32) Better netdev support with handling (auto-)restart mechanism in case of Bus Off Dynamic allocation of Tx and Rx msgs fifos on open(). Release on close(). Set fdusemsi module option back to default 1 (MSI used only if not shared) (writing onto a not-connected channel caused loosing MSI for the the other connected channel) Fixed that Tx/Rx fifo status bits were reset in the exported CAN status pcanfdtst: improved Xenomai RT by fixing usleep() usage Support of the OEM PCI/PCIe device ID 0x0019 Removed some spurious DEBUG msgs uCAN (CAN FD) cmds unused bits are set to 0

Driver Download Version 8.2 (08.11.2016)

Updates: Fixed netdev lock/unlock around device_write() Added information read from linux-can into /sys/class/pcan Increased Tx fifo up to 500 entries Fixed typo in Udev script: ctrl_number is actually ctrlr_number Added two new ioctl to get bit timing ranges as well as available clocks from the driver (pcanfd.h, libpcanfd.h, and libpcanfd.c impacted) Sample_point ratio is taken into account now, when computing bit timings specs Added rtai and xeno as new Makefile targets Removed OFD_DSAMPLEPT bits (pcanfd_open() only): if sample_point is given then it must be given for both nominal and data bit rates The driver now considers the bit rate value only if BRP is not 0 Fixed handling of some errors cases from CAN-FD adapters pcanfdtst(RTAI): creates a better unique task ID Removed forgotten DEBUG logs for PCAN-PCI Express FD Usage of RX_BARRIER mechanism in PCAN-PCI Express FD to prevent from any spurious interrupts Added some control on channel index received from PCAN-PCI Express FD Added PCANFD_BUS_ERROR as a new STATUS message to give SJA1000 applications BUS_ERROR interrupt notifications Added the STATUS message software ACTIVE for SJA1000 based devices. It occurs as soon as the bus is set up Added support of MSI for the PCAN-PCI Express FD (see also new "fdusemsi" module parameter) The SJA1000 interrupt handler is not entirely locked anymory. Only write access is locked The global init of PCAN-PCI-like boards was moved to _probe() function Fixed usage of "irqmaxloop" and "irqmaxrxmsg" when they're 0 on cmd line Speed up of the way Rx frames are read and saved from the SJA1000 Rx buffer Fixed a bug concerning the limitation of STATUS messages, which could cause that further status changes of the bus were not notified Added the new module parameters "usemsi" and "fdusemsi" to ctrl if MSI should be enabled (0=INTA mode only, 1=MSI mode tested, 2=shared MSI mode tested). "usemsi" default = 1 and "fdusemsi" default = 2 Makefile: Added KBUILD_EXTRA_SYMBOLS def to remove 'undefined symbols' messages when building the driver with RTAI libpcan.c: Added const qualifier to each pointer that cannot be modified Posted a soft STATUS msgs when the driver exits from any error cases, to notfiy user application of the end of the error status Fixed how DMA is handled in PCAN-PCI Express FD: now Rx DMA is set once for all while Tx DMA is setup each time the device is opened Fixed the netdev way of copying clocks from pcan (no more intern_prescaler usage) Enlarged bit timing ranges of any CAN-FD PC interface to their max Fixed computation of bitrate_real field when setting bit rate using BRP

Driver Download Version 7.13 (20.10.2014)

Updates: Added a new feature that exports the "Device ID" which might be written into some PCAN devices (such as the PCAN-USB family devices) to sysfs so that it can be read by Udev system and used for creating /dev nodes names. See the new 45-pcan.rules file which now gives examples on how to use it. This "Device ID" may also be used in the "canx" name of the "netdev" (socketCAN) interfaces, by the mean of the "assign=devid" module parameter Please note: the "Device ID" value is ONLY used if its value is not the default value (-1). It can be changed with: "pcan-settings /dev/pcanusbX -d new_value" Please note: column "ndev" of cat /proc/pcan has been enlarged to display canXYZ strings Fixed udev rules for correct naming of /dev/pcanxx symlinks to USB CAN devices: USB CAN devices /dev/pcanxx names start from xx=32, what ever CONFIG_USB_DYNAMIC_MINORS Kernel configuration is Fixed pcan-settings tool to be able to handle 32-bits Device IDs Added support for Kernel 3.17 Added support of the new PCAN-ExpressCard 34 Minor changes in the user manual

Update: From now on, the complete driver will be distributed under the GPL. The 'obfuscated' code for the USB Interface is removed. The Xenomai RealTime Core was inegrated to the driver (at the moment the PCAN-USB and the PCAN-PCC did not support this feature). A new initialisation parameter was added: "bitrate". from now on it is possible to set the default bitrate of the hardware Some smaller BugFixes
