3 bytes to char
by Nikolay Shishkov 02 Jul '15

02 Jul '15

I have a situation where I need to convert a value that is stored as 3 bytes to a char.The can be for example 7ED95, which is reported in 3 consequtive bytes 07, ED, 95.This value in decimal is 519573, which corresponds to a 51.9% SOC. Is the proper way to do this conversion (from the 3 bytes to the value of 51) like this: char soc = (char)(((unsigned long)value[1]<<16 + (unsigned long)value[2]<<16 + (unsigned long)value[3])/10000); I have been doing stuff like that before with unions, but can't remember how either. Thanks, Nikolay

Re: [Ovmsdev] web api

If you ever need to test your connection to anything (web/smtp/databases etc) try using a telnet client (an installable feature on windows) telnet <hostname> <port> If you get a timeout then the host or port is not accessible to you (firewalled). A blank screen on the other hand indicates a successful connection.

I could use some help integrating Tasker-support
by Jille Berends 25 Jun '15

25 Jun '15

Hi all, I'm in the process of integrating Tasker support in OVMS for Android. For those who don't know about Tasker: "Tasker is an application for Android which performs *tasks* (sets of actions) based on *contexts* (application, time, date, location, event, gesture) in user-defined profiles or in clickable or timer home screen widgets. " Currently I use it to automate all kinds of things, like turning on the lights of my house when my phone sees my access point. But it can also be used to add additional intelligence to our cars. For instance: - User gets the possibility to charge by schedule. For instance: When at a certain location, charge at 16A from 1:00 to 5:00. charge at 32A at other times. - OVMS-triggered events: Upon charge done, have something happen on the phone. For instance: play a song, send an email, tweet or whatever. Also, in case you're driving and OVMS reports a SOC below a certain value, start the app that finds the nearest charger - Open up variables (like temperature/SOC) for use in Widget-tools like Zooper. - Even more advanced ACC: Set the "charge done by" time according to a given day/time/location. - Log location/charge/speed/temperature data to phone/web - Enable voice control of charging - et cetera My devskills aren't that advanced, so I hope there's someone here I can team up with to get this thing going. Some basic info on enabling Tasker support: http://tasker.dinglisch.net/developers.html http://tasker.dinglisch.net/plugins-intro.html

Some more Android Wear progress
by Jille Berends 23 Jun '15

23 Jun '15

See attachment. At the moment I'm using data I get from the API by tasker, so not yet directly from the OVMS app. Not sure if anyone is interested in Android Wear support, but hey...it's the closest thing I can get to a KITT at the moment ;)

Nissan Leaf breaking changes
by Nikolay Shishkov 22 Jun '15

22 Jun '15

Hi all, For my project I have changed the Nissan Leaf code to support connection with normal OBD cable. There are still some bugs to sort out but the code seems to function. This is a breaking change for those that use the special OBD cable for Nissan Leaf, and I am wondering if I should branch this off as a separate vehicle file? A "CAR CAN Nissan Leaf" instead of the "EV CAN Nissan Leaf"? Is anyone using the current Nissan Leaf code? Nikolay

understanding polling
by Nikolay Shishkov 22 Jun '15

22 Jun '15

Hi , I am trying to make nissan leaf work with normal cable - on the CARCAN. I am trying to figure out the polling mechanism and I have trouble understanding what the different parameters in the configurations are. In the ampera file I can see: | rom struct | | | { | | | unsigned int moduleid; | | | unsigned char polltime; | | | unsigned int pid; | | | } vehicle_voltampera_polls[] | | | = | | | { | | | { 0x07E0, 10, 0x000D }, | | | { 0x07E4, 10, 0x4369 }, | | | { 0x07E4, 10, 0x4368 }, | | | { 0x07E4, 10, 0x801f }, | | | { 0x07E4, 10, 0x801e }, | | | { 0x07E4, 10, 0x434f }, | | | { 0x07E4, 10, 0x1c43 }, | | | { 0x07E4, 10, 0x8334 }, | | | { 0x07E1, 100, 0x2487 }, | | | { 0x0000, 0, 0x0000 } | | | }; | While in the nissan leaf file I can see the following: | rom vehicle_pid_t vehicle_nissanleaf_polls[] | | | = | | | { | | | { 0x797, 0x79a, VEHICLE_POLL_TYPE_OBDIICURRENT, 0x0d, { 10, 10, 0 } }, // Speed | | | { 0x797, 0x79a, VEHICLE_POLL_TYPE_OBDIIVEHICLE, 0x02, { 10, 10, 0 } }, // VIN | | | { 0, 0, 0x00, 0x00, { 0, 0, 0 } } | | | }; | I can kind of guess some of it. I also found an old e-mail from Mark that describes a structure similar to the one in the nissan leaf file, but the leaf has one extra parameter - I think it is the return message can Id. Any info/advice is appreciated! Nikolay

OVMS hardware sold out at fasttech
by ralph.radmacher＠mac.com 15 Jun '15

15 Jun '15

Dear Dev-Team, I just started adapting OVMS for the Smart ED (fortwo electric drive v3) and ordered an OVMS module for the development. The module arrived, but now fasttech lists the hardware as sold out (at least temporarily). Before I continue with my efforts I would like to know more about the availability of the module for other users. I gathered a lot of data about the CAN bus of the Smart ED (including battery diagnostics) and think the port would be interesting for all drivers of this car. Are you producing other batches or do you switch to other hardware? A perspective of the platform would be great! Please kindly advise. Yours faithfully Ralph Radmacher -Germany-

Fwd: Re: App for Windows Phone?
by Christopher Cook 10 Jun '15

I've thought about this before but not being an OVMS user means I just don't have the motivation (sorry!) A long term cross platform solution would be to develop using Xamarin then much of the (C#) code could be shared across platforms. A basic shared UI can be done using Xamarin Forms but the tricky part of an OVMS app isn't really the UI, it's the server comms/decoding/encoding. Another alternative is allow an HTML UI for the app (as we use for Open Charge Map) which would require a native Cordova plugin for each supported platform to do the low level comms/translation. The plugin would expose a high level api to the app to pass in/out JSON objects that the javascript based app can then use. Alternatively a full HTTP or Websockets based server API that any app can use would remove the need for a native component (standard javascript can't talk to normal sockets).
