Today's passenger vehicles can utilize about 70 onboard computers (ECUs, actuators, and so forth). So let's consider this group an extended family, and just like any family, communication means a lot.

First off, let's establish the basics of how a CAN-Bus network operates. What CAN-Bus does is turn analog, switched voltage signals and sweeps into digital code. Let's take the speedometer, for ...

An engineer asked me a question about how to implement a CAN-bus circuit with the Texas Instruments SN65HVD251 transceiver. He had already studied data sheets and application notes. His key question ...

After I wrote about the CAN bus in a previous blog entry, I decided to get a few CAN-bus transceivers and run several basic experiments. I obtained samples of the SN65HVD251 transceiver from Texas ...
