Description

CPC-PCIe low profile is a passive CAN plug-in board for PCIe x1 slots. CPC-PCIe low profile was designed for industrial series application and has a robust and cost efficient construction. CPC-PCIe low profile supports either one or two CAN channels that can be operated independently with different data rates. The interface comes with the NXP CAN controller SJA1000, that offers good diagnostic attributes.

CPC-PCIe low profile maps the CAN controller(s) directly in the address space of the PC and allows access of the CAN messages with low latencies. Existing software for the supported CAN controller can easily be adapted. For the operating systems Windows and Linux software development kits with identical API are available free of charge.

The CAN communication with CPC-PCIe low profile may be handled either in interrupt controlled mode or in polled mode, interrupt channels are assigned automatically (Plug & Play).

Optionally, CPC-PCIe low profile is available with galvanic separation between PC and CAN bus. A galvanic separation between the CAN channels is also possible by separate DC/DC converters.

Programming Interface

Configuration and CAN communication with CPC-PCIe are done by accesses to the memory address area of the PC. The appropriate data areas are mapped by CPC-PCIe and „plug&play” software into the memory address space. Due to the direct access to the CAN controllers the CAN communication takes place with low latency time.

The memory used by CPC-PCIe is divided in several sections. The control registers allow the detection of the interface type similar to the interfaces CPC-Card, CPC-XT and CPC-104 and the generation of hardware resets for the CAN controllers. The access to the CAN controllers occurs via a separate memory space for each interface. In these memory spaces, the sending and receiving buffers as well as the control registers of the CAN controller are accessible.

A specification describing the access of the CAN controllers and drivers for Windows and Linux are available separately.
