I was wondering if anyone knows how to repeatedly send the same can bus message such as one to control the hvac fan speed to keep it on. I tried the playback feature and it didn’t work. Anyone have an arduino sketch I could use to complete this task?
There’s a couple of options. One, you can create javascript files that do whatever you want. There are lots of examples included in the windows version or you can find them on github here: https://github.com/collin80/SavvyCAN/tree/WIP/examples
Also, there is the custom frame sender. If you fill out the fields properly it’ll send the same frame over and over at a specified interval. Yes, it’s kind of complicated to use. The help files haven’t made it to a binary release yet but they’re also on github: https://github.com/collin80/SavvyCAN/blob/WIP/docs/source/customsender.rst
Or, you can use the fuzzing window. Set the upper and lower ID to the same, set the bits black and white to give you the data bytes you need, set the time interval, and go for it.
