I'd like to capture the CAN traffic while reading the values for analysis later. What's the cheapest way to get data out of the CAN bus?
I purchased the OVMS (v2) with the intent of writing custom firmware that would log CAN traffic. I assumed that I'd need compression, pattern-matching to log only a subset of the data, or some other port to which I could stream the data (DIAG or USB). However, I never did get around to writing any new firmware. I know the memory is limited, but I hold on to some hope that intelligent filtering, or even just a histogram, could provide useful data. In fact, perhaps an initial phase of gathering histogram data, followed by targeted logging, would prove useful - assuming easier options aren't already available. Has anyone worked on custom OVMS v2 firmware for something like this? I'm looking forward to the OVMS CAN-USB, but I suppose that won't arrive soon enough for your project, Tom. Brian
