I'm reviewing the Microchip CAN Analyzer for a Road Test. It'll be used in a CAN Bus that I'm designing. This blog checks how to inject traffic from the Analyzer  |
An Analyzer that Generates Traffic
I'm using the Microchip CAN Analyzer as a development tool. One of the interesting things is that it can also generate CAN messages.
This is very useful as a debug tool. You can configure a CAN receiving mailbox on your microcontroller, then use the analyzer to shoot messages that the mailbox should capture or ignore.
You can generate that traffic from the GUI.
You can define the ID, extended ID, payload, repeat count and delay.
I'll use that mechanism to check if my interrupt based CAN firmware on a Hercules microcontroller fires when needed, ignores when not applicable.
The message ID and extended ID define if this is the case or not.
It 'll also help to see if collision detection and handling works as expected.
Now that I know how to generate that traffic, it'll make my work easier.

I like your simple testing steps.
Learn to walk before you try anything stressful.

Yay, a message sent from the analyzer triggers the read handler on the microcontroller that I programmed.
This analyzer turns out to be very useful. Both for reading traffic and for generating test messages…
