Microchip CAN Analyzer Road Test - part 1: First trials

Jan Cumps

I'm reviewing the Microchip CAN Analyzer for a Road Test.

It'll be used in a CAN Bus that I'm designing. This first test is to see if It can capture data in the logic layer.

 

First Impression

 

I've filmed my attempts to install and try out the software.

 

 

Similar to one of my fellow road testers, I had issues installing from the provided DVD. It worked with the version on Microchip's website.

 

First Test

 

I don't have a physical CAN bus yet. That's WIP. My current setup is on the logic level, treading the 3V3 signals directly from the microcontrollers.

I wasn't able to capture data immediately, but after a few hops and bumps I got it working. The Analyzer logs data on the logic level of my CAN setup.

 

 

Here's a video capture of that:

 

 

That's not a bad result for a noon of playing around. I'll try to send some data from the analyzer in the next blog.

  • Hello,

     

    What parameters did you endup changing to actually read the can messages? I have downloaded all the software and installed under administrator ut my screen is blank, I see message traffic under buts sents and received but no hexadecimal r decimal traffic showing. I am using a OBD2 cable connected to the device, any help would be appreciated. Thanks!

    In hardware setup, I set the Mode to Normal, and speed to my CAN bus speed 500000.

    Terminator depending if this is the 1st or last node, then on. Else off.

     

    In the 6-pin connector, I connect Hi and Lo of the bus to 2 and 3 (check the manual) and ground to 6.

     

    Then I see traffic when  it appears on the bus whn opening one of the trace views.
