I have to temporarily stop work to buy the KVASER Leaf light ($350). I discovered that I really need a CAN bus analyzer to go faster. Getting the messages right is necessary.

I am at the point where I need to keep track of the bus myself and create message traffic. About a week of so I should be able to finish the sample Fuel Level sender (no address claim) and reader.

Thanks for stopping by. I want do both as a reference system, so the project can be black box tested against a known system.

I ordered an old Tek 11801C (a 50 GHz) that will be connected to some handcoded octave m. code over the GPIB for part of the work on the jitter.

I am guessing that means going 480 Mb HS 2.0 USB over 12 MB Full Speed 2.0 USB .... I haven't ordered yet. The LM3S8962 project board has a FTDICHIP 12 MB USB, though I am not using it for the first project. --- I can always push to IPV6 RT ethernet/ip with a GPS module sync to the IEEE 1588. The Luminary Micro is the best $89 I've spent, but the number of options on the eval board, slows down the decision process. What I want to do vs what I can do makes it hard to keep the focus.

OK, so I should seek a Leaf light semi pro version with the built in galvanic (and opto) isolation. Is that something that Maretron and Actisense buyers should look for in a NMEA specific CAN/USB interface?

BTW do you all use octave or matlab in developing? I hope to post some scripts here. One post (in the works) is a javascript browser GUI interface that works in Matlab, Octave and Freemat on windows.

Thanks ....
