Volt/Ampera SOC and more
by Michael Jochum 01 Dec '12

01 Dec '12

Hi, i implement the following code into the FW: unsigned int soc_largest = 56028; // this is from mark, readout from the logs unsigned int soc_smallest = 13524; // this too unsigned int v; v = (can_databuffer[1]+(unsigned int) can_databuffer[0] << 8); if ((v<soc_smallest)&&(v>0)) v=soc_smallest; if (v>soc_largest) v=soc_largest; car_SOC = (char)((v-soc_smallest)/((soc_largest-soc_smallest)/100)); i got funny Outputs in the iPhone app. Something between 0 and 100%. Not match to the real state. Full can display as 0% or 20, or...... Empty can show as 100%, or something else. This code (org. mark) works: car_SOC = (char)((can_databuffer[1]+((unsigned int) can_databuffer[0] << 8))/644); With this i got 21-87% for the soc. BTW: i thing it is a good idea to deactivate the minSOC warning. It is not nessary for the Volt/Ampera. I activate the internal GPS (OVMS_INTERNALGPS) and get the position from my car. GREAT WORK. I got no Info about the VIN, the OVMS FW and the car type in the iPhone App. 1.3.2 build from the git. Bye michael

1.5.1
by Mark Webb-Johnson 28 Nov '12

28 Nov '12

Firmware 1.5.1 has been built for all platforms and is now on github. The primary focus of this release has been adaptive reporting and simplifying provisioning. Due to the drastic reduction in cellular data usage with this release, and improvements in cellular connection handling, this firmware is recommended for all end users. Github issues addressed (since 1.2.9) are: #93 Car: Notify server/app when charge has completed #92 Try TCP reconnect, rather than full GPRS re-init, if server connection fails #90 AP via SMS #89 Report GSM operator #86 Get ICCID from SIM during startup #84 Detect lack of comms between PIC and modem #82 Adaptive Reporting #80 Make GSMLOCK use short service name #79 SMS/PUSH notify if alarm is activated #78 can_poll0 100 vs 102 check #77 Option for GSM Network selection #76 SMS HELP command #75 Car: Basic (stub only) Renault Twizy Support #74 Car: SETUP (DIAG) mode for firmware #71 Car: Send line voltage level back to server #70 Car: Send hardware version along with firmware version #69 Wakeup temperature subsystem when car is woken up #58 Car: Strange range when low on power #57 Car: Motor temperature overflow Regards, Mark.

Gone quiet...

I've received quite a few OVMS development eMails in my inbox these last few days, and I'm having trouble finding the time to respond properly. Apologies if you are waiting on something from me. I'm also snowed under at my day job with a huge product launch this coming Friday. After that, things should get easier. I'm working through the backlog, so please be patient :-) I should be able to catch-up over the weekend. Regards, Mark.

Some Twizy Graphics
by Mark Webb-Johnson 21 Nov '12

21 Nov '12

Bruce has submitted some nice graphics for the Twizy, and I've just added them to the iOS App and released a version to TestFlight with both Volt/Ampera and Twizy graphics. Many thanks to Bruce for his hard work on this. The other reason for this release is because the provisioning profile is about to expire (8 days) and this release renews it for another year. Regards, Mark. P.S. With all the Michael's working on this project, things were getting confusing. Now, having a Bruce from Australia is so much easy to remember :-) > From: "Bruce McMillan" <brucemcmillan(a)exemail.com.au> > Subject: Some Twizy Graphics > Date: 20 November, 2012 6:37:10 PM HKT > To: <ovmsdev(a)lists.teslaclub.hk> > > > Hi Mark, > > > Although I don't own a Volt at this time, I'm very interested in its progress.

Interesting article forwarded to me today by one of my Linux hackers: https://lwn.net/Articles/518923/ I'd seen the 2010 paper before, but not the 2011 refresh. Regards, Mark.

New features: sufficient charge alerts, ideal max range
by Michael Balzer 14 Nov '12

14 Nov '12

Mark, I just checked in my latest Twizy updates: https://github.com/dexterbg/Open-Vehicle-Monitoring-System/commit/0a70e483b… These contain two extensions that could be generally useful: 1) As the Twizy "ideal" range varies widely depending on your driving, geography and environment, I implemented a feature for that config. 2) If I just need an intermediate charge for a certain SOC or range (to get home for example), I can now activate an alert for one or both values. I used the next three free feature slots for these: #define FEATURE_SUFFSOC 0x0A // Sufficient SOC feature #define FEATURE_SUFFRANGE 0x0B // Sufficient range feature #define FEATURE_MAXRANGE 0x0C // Maximum ideal range feature I know, feature slots are getting full... what do you think?

Joining forum without a TMC account
by John Hatchett 13 Nov '12

13 Nov '12

I was wanting to join the forum at openvehicles.com but the form for creating a new user account requires "TMC Forum User" . Now that OVMS is expanding beyond the Tesla, can the requirement be removed or do I need to go get a TMC Forum account as well?

General issue: metric system ;-)
by Michael Balzer 09 Nov '12

09 Nov '12

I hesitate to touch anything outside the can module yet, but I would like to store range values in kilometers. Reason: my car uses km and I'm losing precision if converting them to integer (!) miles. 1 mi = 1.609 km Are there any thoughts on this? Could it be just a labeling switch or does the server/app protocol need miles? Regards, Michael -- Michael Balzer * Paradestr. 8 * D-42107 Wuppertal Fon 0202 / 272 2201 * Handy 0176 / 206 989 26
