Twizy controller configuration / CANopen SDO protocol
by Michael Balzer 19 Jan '14

19 Jan '14

Hi everyone, sorry for dropping behind/off last months, lots of work. I've not been able to catch up on the framework advances yet, but nevertheless wanted to announce a major Twizy update I'm currently working on. This update enables access to the SEVCON controller configuration of the Twizy. Low level commands allow read and write access to all SDOs. Macro commands allow to easily change common settings like maximum speed, maximum torque, power and recuperation levels and drive profile characteristics. There is a potential benefit for other vehicles from this development: I've done a basic CANopen SDO protocol implementation for this. The implementation is specific to the Twizy only because it's limited to addressing just node #1 and currently only supports expedited SDO transfers, not segmented. The node id could easily be made variable, and segmented transfers should be not much of a problem. It still is nowhere near a complete CANopen protocol implementation, but allows SDO reading and writing. Tell me if this sounds useful for other vehicles. As I've not yet integrated your latest work, I've pushed this into my Github repository first: https://github.com/dexterbg/Open-Vehicle-Monitoring-System I'll also wait for some more user feedback before going on, and I also want to implement support for the Twizy 45 before merging this in. Just wanted to let you know in case you wonder about rising OVMS hardware sales lately ;-) Oh, and I wish you all a happy new year!

Ampera end of charge notice
by Paul Churchley 19 Jan '14

19 Jan '14

I have noticed that when I leave the Ampera plugged in but already fully charged I seem to be getting messages through saying that the charge has finished. Does the Ampera start charge at regular intervals even if it is already at 100%? Paul

Twizy release 3.1.2 / CANopen segmented SDO reads
by Michael Balzer 18 Jan '14

18 Jan '14

Release 3.1.2 is now online. I skipped checking in 3.1.1 as that was more or less just an intermediate step for the log access functions. There's now the readsdo_buf() function which does a segmented SDO read into a buffer. So this can be used to fetch strings and domain data (binary) from the SEVCON. The new log and alert functions use this to retrieve error descriptions, which the SEVCON fortunately provides... I love this controller :-) Regards, Michael -- Michael Balzer * Paradestr. 8 * D-42107 Wuppertal Fon 0202 / 272 2201 * Handy 0176 / 206 989 26

Yes, that's annoying. Partcularly when you want ti demo the app. Denis. Paul Churchley <paul(a)churchley.org> a écrit : >_______________________________________________ >OvmsDev mailing list >OvmsDev(a)lists.teslaclub.hk >http://lists.teslaclub.hk/mailman/listinfo/ovmsdev

Re: [Ovmsdev] Ampera end of charge notice
by Denis KRAUTH 17 Jan '14

No, that's probably a bug. When I plug in my Ampera with delayed charging, I also used to get warnings every couple of minutes, so I had to turn the notifications off. It would be nice if it could be fixed. Denis.

Development

Now I have taken my first look at the Github I feel rather dejected. I thought I was a reasonable PHP programmer but looking at the code for the vehicle and server I find that I am hopelessly out of my depth from a coding perspective. I know php so the fact it is perl doesn't help. There is a lot of commonality but it is sufficiently different to make it difficult for me right now. It isn't that the code is bad... it isn't bad - it looks great! No, it is just that I think I am so out of practice combined with it being perl I think I am not going to be as much help as I had imagined (hoped)... well, not for quite a while anyway :-( Still, I am sure there are many things that need doing that I can do so I look forward to helping with those. I perhaps just need a bit of guidance on what needs doing that I am actually able to do! I think a crash (or not so crash!) course on perl is my starting point. My php and general programming background will mean I pick up the basics pretty quickly but it is the finer points that will take a while I reckon. I'll start on that this week and then at least I might be able to understand what has already been coded and maybe tackle bugs etc even if I find it difficult to code from scratch. In the meantime, I am also getting to grips with Github... it is also not as easy as I had imagined and I am a little scared that I might do something that corrupts the origin repo! Heeeelp! I am using command line Git and Windows Github at the moment but I am about to install Eclipse so I shall hopefully use that for Git instead as it is all nicely integrated. Does anyone else use Eclipse? I also have Visual Studio 2013 for Windows development. I am wondering if I might be able to create a version of the phone app for Windows phones... would that be useful? I am not a Windows developer but creating Windows phone apps is something I would like to get to grips with so again, it wouldn't be quick but I might be able to come up with something useful. Something else I could probably do is a web interface (or develop the existing one if it already exists) to bring the phone app functionality to the web? Any use? I am very comfortable with databases and mySQL so if there is any database stuff that needs doing I would be keen to be involved. There is so much for me to do to get me up and running it is almost overwhelming! I must just take it a stage at a time. Any guidance/advice on where you think I would be wise to start would be very much appreciated. Any suggestions? Paul PS I am not trying to "muscle in" on any aspects of OVMS... I am just in "brain-dump" mode for now until I find my place in the team... where ever that happens to be! I am cool with doing anything I am able to do... or nothing, if that is preferred :-)

Web App?
by Paul Churchley 14 Jan '14

Hi All, I provisioned and installed the OVMS module on my Vauxhall Ampera today and although it seems a little intermittent I suspect that it is nothing more than dodgy phone signal as when it works it works superbly. So, now it is up and running and that my Pickit 3 programmer will be arriving tomorrow I feel that I want to start to learn a little bit more. To that end, can I ask a few questions that came up through the install: - Installation documentation I have read the installation manuals for the Twizy and Roadster. They helped me a lot during the install (thanks) but I feel that there is so much common ground across all models that we could benefit from a single installation and user manual for the common bits rather than separate manuals for each model. There will be so many models that can potentially install OVMS that having a manual for each model would probably be untenable. A single manual with a section for the common bits and perhaps appendices for the model specific parts might work well? Setting up the module for the Ampera was not at all obvious. I had to read the forum to discover how to set the CARTYPE to VA and CANWRITE to 1. Did I miss that bit somewhere in the documentation? - Android app Installing and getting the Android app running was straight forward but again it really needs some basic documentation. The app seems not to configure itself differently depending on the car type. The app seems to be configured with functionality that is not implemented on the Ampera (e.g. setting charging current, temperatures that aren't appropriate for the Ampera (?) etc). It would be good to have the app configure itself appropriately with only those functions that are implemented for the car type. It would be nice to be able to get all the same functionality that is available from SMS commands through the app including the setting of the car type etc. I suppose it is possible that you can already do that but it isn't obvious how without there being some basic documentation :-) - Web app Is there a web app (web site) to give you access to OVMS functionality through a web page interface? I would imagine that this would be most useful. As with the Nissan Leaf CarWings which has a phone app and a web interface allowing people control of their car through a normal web page interface. I am a web developer (rusty!) so this is an area I might best be able to contribute. - Programming API Given that there are Android and IOS apps and potentially a web interface it makes sense if there was a published API. Is there one? As I say, these are in no way criticisms... just observations/comments on my experience and things that have occurred to me whilst doing the installation. So, next step I suppose is to set up a development environment and to learn how to use Github. Is there a TODO on Github? What is the best way to get involved? Should I just pick something on the TODO and get stuck in or is there someone coordinating the development? How does it work? Paul

Hi All, In addition, when I use the Android App for my Ampera, I first see a grey Tesla Roadster for a couple of seconds, before I see an Ampera. The app is very sleek, but this is a little embarrassing when I want to make a demo of OVMS. Just my 2 cents... Denis.

Model S Data connector
by Otmar Ebenhoech 13 Jan '14

13 Jan '14

Hello OVMS creators, I'm new to the group, but some of you know me already. I'm doing crazy things with a Model S and a VW camper which you can see via the link in my sig. I'd love to have service access to the Model S similar to what the service techs have with the TDS software. Without that tool I can't even bleed the brakes or cooling system. I don't like the idea of trailering my out of warranty vehicle to a service center every time I need to do simple maintenance. I realize that kind of access may never happen, but I figure I have to start somewhere and I assume that would be sniffing the CAN bus. As a small start in that direction I wanted a connector for under the center console with all the pins populated. Mark was kind enough to offer the parts: 173631-1 and 173851-2 which are not common and in stock in the US. I had already found that it looks just like the car side stereo connector for Mazdas from the 1990's and those can be had on ebay for $6 delivered so I bought a couple. http://www.ebay.com/itm/330520850374?item=330520850374&viewitem=&sspagename… They arrived today, and though the quality seems poor and the fit is snug, the connector does fit. The other non matching connector can be used for extra terminals to fill out all the holes, but getting them out without damage is a challenge without a proper tool. It's clear that you all have already made great discoveries in EV monitoring and control. I'm looking forward to sharing what we learn here. -Otmar Otlist09(a)evcl.com Stretchla Project: http://cafeelectric.com/stretchla/ Zilla Support is still at: http://cafeelectric.com/Ssupport.php
