Support Question of the Week: Using a CAN Interface

Every day, the Total Phase support team receives many questions about our tools as well as working with USB, I2C, SPI, and CAN. Starting this week, Total Phase will feature a “Support Question of the Week” on different tips and tutorials for how our products can be used.

Q: I'm working on a new CAN bus product, and we're currently looking for a CAN interface that supports the following features:

  1. 11-bit and 29-bit CAN identifier
  2. baud rate of 250Kbps and 500Kbps
  3. ability to transmit CAN messages in response to a received message

Do you have any tools that fit these requirements?

A: Thanks for your question! It looks like we have two options to meet your requirements. The Komodo CAN Duo Interface is a powerful two channel USB-to-CAN adapter and bus monitor. The Komodo CAN Solo Interface is a single channel USB-to-CAN adapter and bus monitor. As a two channel device, the Komodo CAN Duo can perform monitoring on one channel while simultaneously transmitting on the second channel. The Komodo CAN Solo is also capable of performing both functions, but is restricted to one at a time.

Both Komodo interfaces support up to 1 Mbps baud rates. With the free Komodo GUI Software (downloadable from our website), we offer support for both 11- and 29-bit CAN IDs. For more information on CAN IDs using the Komodo GUI and Komodo interface, check out the following link here.

The Komodo interface can be used to actively send and receive messages on the CAN bus. Regarding your requirement for a tool that can transmit a CAN message in response to a received message, we would recommend that you use our API for this function with the Komodo interface. The Komodo GUI itself is capable of more simple operations, such as sending periodic messages. However, for more complex processes, we offer our royalty-free API, available in many languages including C/C++, C#, VB, .NET, and Python. You can check out our API files under the Downloads tab here.

Good luck using the Komodo CAN Interface for your new CAN product! Post your comments here, or if you have any questions, feel free to email us at sales@totalphase.com or support@totalphase.com.
