CAN Sample Application

The following C++ application demonstrates use of the ADS PeliCAN driver driver.

The application is intended to be run on two devices connected on a CAN bus. One device becomes the 'sender' and the other the 'receiver'. CAN messages are cycled from the sender to the receiver and then back to the sender. The sender checks that the messages returned to it contain valid data. The sender also tracks throughput statistics, which it displays when the transmission is complete.

See below for app, source code and information about using CAN with managed code.

Requirements

Requires ADS PeliCAN v1.1 compliant CAN driver (or later)

Usage

Instructions:

Compile and run SampleCAN on two devices that are connected on a CAN bus.
Select the same baudrate for both devices.
Designate the first device as the 'receiver'.
Designate the second device as the 'sender'.
On the 'sender' device, select the number of message cycles to run.
When all cycles have completed, throughput statistics will be displayed.
Press 'q' to quit the application at any time.

Update
We've updated the application to use the 1.2 version of the PeliCAN driver. The sample will continue to work with version 1.1 of the driver, but the call new IOCTL to query the driver version will fail.
