CPCI CAN Interface

The CPCI-CAN/400-4 is a CompactPCI board in 3U format that features four electrically isolated CAN High-Speed interfaces according to ISO 11898-2. CAN is driven by the esd Advanced CAN Core (esdACC) CAN controller implemented in the Xilinx Spartan 3e FPGA. The CPCI-CAN/400-4 provides high-resolution hardware timestamps.

IRIG-B

The CPCI-CAN/400-4 optionally features an IRIG-B interface that offers inputs for analog or RS-422 IRIG-B coded signals. Both are electrically isolated. An additional microcontroller controls IRIG-B evaluation. This module uses the IRIG-B directly for CAN timestamping.

Connectivity

A 25-pin DSUB connector in the front panel connects all I/Os.

PXI Interface

The CPCI-CAN-400-4 optionally features a PXI interface. The signals TRG 0-7, CLK 10 and STAR are controlled via the FPGA. The signals LBL/LBR1-12 are looped through. The PXI interface is available on request.

Software Support

CAN layer 2 (CAN-API) software drivers are available for Windows, VxWorks, QNX, RTX1 and Linux supporting up to 24 CAN nets. Drivers for other operating systems are available on request. The CANopen software package is available for Windows, VxWorks, Linux, QNX, and RTX. ARINC 825 as another higher layer protocol is available as an option for Windows, VxWorks, QNX, Linux, and RTX.

Driven by esdACC (Advanced CAN Core)

Basic Product Features:

• CAN ISO 11898-1 protocol compatibility
• 11-Bit and 29-Bit CAN IDs
• Bit rates from 10kbit/s up to 1 Mbit/s supported
• Receive buffer (64 CAN messages 2)
• Complete access to CAN error counters
• Programmable error warning limit
• Error code capture register
• Error interrupt for each CAN bus error
• Arbitration lost interrupt with detailed bit position
• Single-shot transmission (no re-transmission)
• Listen only mode (no acknowledge, no active error flags)
• Automatic bit rate detection (software supported bit rate detection)
• Acceptance filter (4-byte code, 4-byte mask)
• Self-reception mode (Reception of ‘own’ messages

Superior esdACC Features:

• Operating system independently programmable via esd’s NTCAN-API
• 32-Bit register interface optimized for CAN needs
  • Easy to program
  • Transmission and reception of CAN frames with a minimum of register accesses
• RX and TX timestamping (64-Bit wide, bit accurate, resolution may vary with input clock, in any case = 62.5 ns, usually 20.833 ns)
• TX FIFO (8 CAN frames deep 2)
  • Providing the means to generate 100% busload even with non-realtime operating systems
  • Providing the means for real back-to-back transmission
• Reactive and frame accurate abortion of transmissions
  • e.g. for driver timeouts
  • ISO11898-1 conform
  • Aborted frames in FIFO not blocked by low priority TX
• Hardware timer to provide accurate software timeouts beyond operating system accuracy
• Bus mastering in RX direction takes the load off host CPU (needs bus master capable local bus to host interface)
• Optional integration w/ 32-Bit microcontroller to give further relief to host CPU
• Optional sources for timestamps (e.g. IRIG-B)
• FPGA technology allows tailoring features to customer needs, incl. optional integration w/customer FPGA content.
• Driver Availability: Windows, Linux, QNX 1, VxWorks 1, RTX 1
• Available higher-level protocols: CANopen, ARINC825, J1939
