Peak PCAN PCI QNX Resource Manager

QNX resource manager for PEAK-System PCAN-PCI CAN bus interface cards.

This project provides a native QNX resource manager implementation for PEAK PCAN-PCI devices, enabling real-time CAN communication in embedded systems running QNX Neutrino RTOS.

The CAN frame format is defined in can.h, based on the Linux SocketCAN specification (https://github.com/torvalds/linux/blob/master/include/uapi/linux/can.h):

/*
 * Controller Area Network Identifier structure
 *
 * bit 0-28 : CAN identifier (11/29 bit)
 * bit 29   : error message frame flag (0 = data frame, 1 = error message)
 * bit 30   : remote transmission request flag (1 = RTR frame)
 * bit 31   : frame format flag (0 = standard 11 bit, 1 = extended 29 bit)
 */

struct can_frame {
    canid_t can_id;   /* 32-bit CAN_ID + EFF/RTR/ERR flags */
   uint8_t    len;      /* Data Length Code (0..8) */
   uint8_t    __pad;    /* padding */
   uint8_t    __res0;   /* reserved / padding */
   uint8_t    len8_dlc; /* optional DLC for 8-byte payload length (9..15) */
   uint8_t    data[CAN_MAX_DLEN] __attribute__((aligned(8)));
};

includes cansend and candump utilities similar to Linux can utils.

ready to build as QNX projects with project files or Boost build

Build using your target SDP Set the environment variables for the appropriate QNX SDP version: Windows: Run the qnxsdp_ver-env.bat script. Linux: Source the qnxsdp_ver-env.sh script.

In the Project's root directory, type make. This command build all binaries for all target platforms.

# Start resource manager
canrmd -d can1 -s 800

# Send a CAN message
cansend can1 123#DEADBEEF

# Dump CAN messages
candump can1

• -d device : Specify PCAN device node (e.g., can0)
• -s bus_speed : Bus speed in kbit per second (e.g., 125 for 125kbit/s)

Possible speeds: 10, 20, 50, 100, 125, 250, 500, 800, 1000

• Requires PEAK PCAN-PCI hardware
• Tested on QNX 7.0, 7.1 and 8.0 with x86 platforms
