CAN-RE-TOOL
by Mark Webb-Johnson 13 Jul '13

13 Jul '13

I've launched a new project on github: https://github.com/markwj/CAN-RE-Tool Background is that I'm pissed how costly CAN-USB adaptors are. For what they are, the cost is too high and the software is terrible. If you want the good software, the hardware cost is beyond ludicrous (thousand of dollars). Bill of materials for these things is around US$20-US$30. Street price is US$150 upwards (excluding shipping). I've got a hardware design (based on PIC32 and MCP2551 chips, plus a little power regulator), and I''m working with China factory to see if we can get these down to US$50-60 (including shipping). On the software side, I've released the CAN-RE-TOOL source code. This is perl code (but with a few libraries necessary), and pretty neat. Still very much a work-in-progress, but very usable. Some notes: It should be cross platform - just textual curses based. But, only tested on OSX so far. Linux should be easy, but not sure about Windows. It works with an Input-Transfrom-Output model, with optional displays. You can define the input as either a disk-based log file (CRTD format) or a CAN-USB adaptor to input from. The output can be discard, disk-based log, or CAN-USB adaptor to output to. The transforms take the input and perform optional transformations. At the start, the main transform is 'Uniques' - which find unique messages and keeps a history of updates to them. The input can be real-time or sped-up/slowed-down. Various real-time displays can be called up, including Cyclic and Scrolling real-time message lists, Unique message display, and coverage (which shows just the parts of the unique messages not currently understood). The uniques system identifies messages by a combination of CAN arbitration IDs plus optional data bytes within the message (an example being Tesla Roadster using byte #1 of ID 0x100 as a unique message). Decoders can be defined, to produce sensors from the messages. These decoders document the protocol and message coverage. Everything is implemented as plugins, so it is very very expandable. I've working on a bunch of experimental plugins to do statistical and heuristic style analysis looking for patterns in the messages captured. Control is via mouse, keyboard commands, or scripts on disk. Here are some screens, to give you an idea of what is possible: Selecting a CRTD log file as the input source: Scrolling CAN message display (input is a CRTD log file being played back in real time): Uniques message display (note the decodes on the right, and message count + interval towards the left): Coverage message display (everything not '*' is unknown): The whole point of this is to provide a system to capture messages from the can bus, work out which messages are unique for that particular car, provide a facility to decode the messages to user-readable sensors (speed, SOC, CAC, odometer, etc), and finally to allow the vehicle message documentation to be produced. It does all this today. Perl is used to make this all scriptable and extremely quick/simple to extend. In future, I'm also interested in providing a facility to simulate a vehicle (we can only do that now by replaying a log file back out). OBDII style support work also be useful (include a PID scanner). This is mostly for me, but I'm putting it out there and sharing it in case anyone else needs this. Regards, Mark.

Twizy to C-Zero
by Nikki Gordon-Bloomfield 02 Jul '13

02 Jul '13

All, I'm just about (hopefully) to sell my Twizy back to the dealer after yet another fault. (Two service light errors and one broken window) I'm likely to switch to either Volt or C-Zero. The latter is my choice, since it's all electric and substantially cheaper to buy. But the Volt may also get a look in if the dealer gives me a good deal. Here in Europe neither have any kind of telematics. I know the Volt is pretty well supported these days. What of the C-Zero? Did anyone start logging? If I do get one, I'm happy to log stuff, but I'll need help decoding it as I'm not very experienced as a coder. I'm more of a…hacker. ;) Nikki. P.S. Renault is trying to blame the two logged errors on my Twizy (multiplexing bus) with OVMS. Know any reason why it would cause any issues? It's not set to write to CAN bus anyway…

Hi Nikki, As an Ampera owner, I have to warn you: if you test drive à Volt, you will order one :-) And the European Ampera/Volt community would love to have you on board: there is still some hacking to do.

DIAG port to bluetooth
by Giannis Bakas 28 Jun '13

28 Jun '13

Hi all, is it possible to use a serial to bluetooth dongle on the DIAG port of the module to get data via bluetooth, requesting data with "MSG commands"? What I want to do is to use OVMS like a bridge between my car and my parrot device (Android device) in order to visualize the data I get to the screen. I want to avoid the SIM card and to get data from the server. Best regards, Giannis

missing the charge connector icon
by Kevin Sharpe ZCW 17 Jun '13

17 Jun '13

I've noticed a number of times that the iPhone app is missing the charge connector icon when a Tesla Roadster standard mode charge has completed. Interestingly, the app is still showing the charge port as white on the 'car' tab indicating (I guess) that power is connected. Removing the connector from the car, closing the flap, opening the flap, and reconnecting will allow the app to recover and continue displaying the connector icon as normal. Sending a chargestart text message will also work (sometimes). I'm using app version 1.3.5 (20130604) and firmware 2.3.1/TR/V2 A stat text returns "Standard – Charging Stopped" Any ideas what's wrong?

Open Vehicles iOS 1.3.5 (20130604)
by Mark Webb-Johnson 08 Jun '13

08 Jun '13

I have just released an experimental build of the Open Vehicles iOS App. This includes Open Charge Map (OCM) integration support. Please note that there is no roll-back procedure for this build. You may be required to un-install and re-install the App again at a later stage (losing settings, and thus having to re-setup your vehicles). We would appreciate your help with testing this build, in particular your participation in this test will allow us to get valuable feedback on any crashes experienced. Regards, Mark. Platform: iOS Version: 1.3.5 (20130604) Team: Open Vehicles Release Date: June 4, 2013 Size: 18.0 MB Expires: 5 months, 2 weeks

Strange Twizy Message.
by Nikki Gordon-Bloomfield 06 Jun '13

06 Jun '13

Hi guys Just got the following message from my car: "Volts: !SD:4075mV !C1:+4075mV Temps: !SD:225C !M1:-1C" It's about 10 degrees C right now, and SOC is reported as 82 percent. Any ideas what's going on? I can tell the voltage is okay… but the temperature warning??? Nikki.

Tesla Roadster - COOLDOWN (not working for me)

Ambient (garage open on 1 side) was 38C. I left it for 8 minutes, after which time the PEM was at 48C, motor at 63C and ESS at 40C. Ambient was 39C. I tried increasing current to 13A (again 220V, range mode), and left it for a while. After 21 minutes, PEM was 48C, motor was 51C, ESS was 37C and ambient was 47C. That is a total of 29 minutes so far, and I've managed to cool the ESS 39C->37C, but heat up my garage 38C->47C. I restarted the range mode charge at 10A and this time left it for about an hour. After that, PEM was 46C, motor 42C, ESS 39C, and my garage a blistering 59C. This pretty much recreates my experiments from last summer. After more than an hour, the ESS temperature was unchanged, but I had managed to heat up my garage from 38C to 59C. Not sure if the term 'cool down' is appropriate for this :-( Does any of you do cool down regularly (manually, or with Tattler)? If you do, what settings do you use (voltage, current, duration) and what sort of temperature drop on the ESS do you see? Last year, it was suggested I try at a higher current, but that seems to defeat the purpose. Any suggestions? Regards, Mark.
