Introduction

Introduction

This page gives an overview of can driver which is available as part of the Xilinx Vivado and SDK distribution.

How to Enable

Source path for the driver:

https://github.com/Xilinx/embeddedsw/tree/master/XilinxProcessorIPLib/drivers/can

The driver source code is organized into different folders. The below diagram shows the can driver source organization can.
|

  • - Doc - Provides the API and data structure details

|

  • Examples - Reference application to show how to use the driver APIs and calling sequence

|

  • Source - Driver source files

Features Supported

Controller Features:

  • Industrial (I, –40 to +100°C junction temperature) and automotive/defense Q-Grade (Q, –40 to +125°C junction temperature) device support.

  • Supports both standard (11-bit identifier) and extended (29-bit identifier) frames

  • Supports bit rates up to 1 Mb/s • Transmit message FIFO with a user-configurable depth of up to 64 messages

  • Transmit prioritization through one high-priority transmit buffer

  • Automatic re-transmission on errors or arbitration loss • Receive message FIFO with a user-configurable depth of up to 64 messages

  • Acceptance filtering (through a user-configurable number) of up to four acceptance filters

  • Sleep mode with automatic wake up

  • Loopback mode for diagnostic applications

  • Maskable error and status interrupts

  • Readable error counters

Driver Supported Features

The CAN Standalone driver support the below things.

  • All controller features supported.

Test cases:

         In AXI CAN, we are running below examples

  • xcan_polled_example.c

                 It configures the CAN controller in loop back mode with no interrupt enabled and verifies the data received with data sent.

                https://gitenterprise.xilinx.com/embeddedsw/embeddedsw/blob/master/XilinxProcessorIPLib/drivers/can/examples/xcan_polled_example.c

  • xcan_intr_example.c

                 It configures the CAN controller in loop back mode with interrupts enabled and verifies the data received with data sent.
