You can disregard this warning from the other user, it's BS.By the way, I am french as well as my answer isn't due to a lack of understanding of that text.Regards,Laurent, I wanted to point out to the author: You mention "coloumbs" several times... Based on the context it should be "columns". I now have a working system (but not yet installed in my car.) on Introduction, It looks like the centre console from a modded ricer (no, not racer, ricer!!!) The demo code entitled “Demo 3” will allow you to send custom messages using joystick of the Sparkfun shield to the change the values live. My "be nice" and "constructive comment" is for you to keep your post up and encourage the curiosity to learn and explore the world around us. SuperSniffer is a software tool built specifically for analysis of CAN bus. Though there are many cost-effective devices for communicating with the CAN bus, the software needed to interact with these devices can be lacking, so you’ll often need to write your own. Jul 20, 2020 #1 Hello all, So let's start: - I want to add an input option to my old car stereo. Almost complete freedom is afforded in the design, and the result is easy to duplicate. Advertisement. The same with eye protection , hearing and such. Where the tutorial gives you example code, simply replace the example code with this code. Tis a scary thing when I get people thinking , I do want to see your ver. You can use an oscilloscope and count the time between pulses to determine the baud rate of the CAN bus network, depending on your oscilloscope, standard baud rates are 125 kbit/s, 250 kbit/s, 500 kbit/s and 1 Mbit/s. Read part 4 then if you are unfamiliar with CAN bus frames. Incidentally, it was observed that the frame that enabled the dials also happens to contain the channel for oil temperature, engines status, the mileage counter and the indicator lights thus solving the missing values problem. Should you wish to compare different channels or different frame ID’s at the same time without changing the values in code, you will need to add additional functions to the code. [online] Available at: http://www.obdsol.com/knowledgebase/on-board-diagnostics/what-is-obd/ [Accessed 29 Nov. 2017]. The other wires can be whatever colour the manufacturer chooses as they aren’t standardized. on Introduction. Plug up everything , Put on the side cover ( s ). Once you have the process of retrieving data and processing it using the aforementioned processes, you may wish to try using SuperSniffer. you already have a cd drive, and that computer probably came with powered speakers. If you are unable to figure out which lines are CAN bus, try probing the matching pairs of wires with the oscilloscope to see pulses of data like those seen when practising, if you are still unable to locate the CAN lines, there may not be CAN lines going to that specific device. I'm wondering if anyone is familiar with any sort of hacks for custom firmware or customizing of any kind of dvd head unit. you done it well done it looks nice and do be honest i have never seen a car stereo installed to a computer what psu are you using for your computer?
