OVMS logo

We need to change the OVMS logo, to better reflect the vehicle independence. The existing logo is too much Tesla. Felix has kindly prepared a couple of options for us, attached below. My preference is for the one with the car outline (even though it retains a hint of Tesla), as it emphasizes the vehicle comms aspect. This is quite urgent, as the Teslive people are pushing for artwork. What do you guys/gals think? Regards, Mark

OVMS v3
by Mastro Gippo 19 May '17

19 May '17

Hi all, I'd like to resurrect an old conversation. As we know, the current PIC is quickly running out of resources and maybe it's time to switch to a better platform. Two CAN buses are now desirable too. A microSD slot and direct USB connectivity wouldn't hurt either. I will probably have to design a similar hardware for myself, so I'd like to contribute to the OVMS by sharing the HW platform if you want; no strings attached of course, if you decide that there's no need for the upgrade, I'll keep on working on my project by myself! :) That said, I'd like to throw a few ideas to the table. - MCU: I'd like to use an STM32 micro. They seem to be emerging as the standard choice for diy ARM projects, and this offers a few interesting opportunities: -Programming it in c/c++ with the manufacturer CMSIS standard libraries (boring) -Programming it with the mbed.org SDK. Unfortunately no dev boards are available with dual CAN bus, but it will be easy to move to the correct micro of the same series once most of the software is ironed out on a dev board like the https://mbed.org/platforms/ST-Nucleo-F302R8/ -Programming it with an RTOS. NuttX would be my choice, as it's the one used in the Ardupilot Pixhawk platform, and I'd like to learn it. This would mean a steeper starting curve, but a lot of flexibility later as a lot of stuff is handled on the OS level (network stacks, SD card & filesystems, multitasking...). FreeRTOS is a nice option too. I'd like to use the STM32F405RG as it's the most similar to the one found on the Pixhawk, but of course I'm biased because of that, and that micro is quite overkill for the task. We can of course use a lower specced part and lose some RTOS fuctionality as long as it has 2 CAN buses. - MODEM: I have no experience in this field; is the SIM908 still a good choice or does anyone think that we should try new platforms? I like this, but I don't know if the price puts it out of budget: http://www.telit.com/telit/Pulsar/en_US.Store.display.1001./ge864-gps On the bright side, it can be programmed in python, so we can offload some of the work to the modem. This *could* allow us to free some space on the PIC, and keep that platform without changing MCU.. - Enclosure: I think that, even with the new MCU, we can still fit the old enclosure. Is that ok, or should we think about a more automotive-friendly one? Maybe waterproof for the twizy? And that's it. I think that the core SW developers should voice their opinion, as there is a lot of work to be done on that front. A huge problem will be keeping backwards compatibility to add features for the v2 users, so we should discuss about this too. Regards MG

Building with free C18 compiler
by Matt Beard 19 Nov '15

19 Nov '15

Have I missed a decision to no longer support the free C18 compiler - or has it been like that for ages? I am trying to fix an issue in the iMiev code, but can no longer build 2.6.5 due to needing the full compiler and no way am I paying £300 for it. Matt Beard

C2DM is deprecated, no new sign-ups
by Lee Howard 16 Nov '15

16 Nov '15

I've got my own OVMS server going. However, I wasn't seeing notifications on my phone (Android) since moving away from tmc.openvehicles.com. Looking at the ovms_server.pl code it appears that ovms_server.conf requires this section: [c2dm] email=<email> password=<password> accounttype=<unknown> [This "c2dm" section, along with the "server", "master", and "log" sections are undocumented in the docs/HOWTO.server.txt file.] Okay, so it would seem that I need to set-up a C2DM account with Google and put that info into the conf file. But, Google has deprecated C2DM in favour of Google Cloud Messaging (GCM), and Google is not granting any new C2DM accounts... http://developer.android.com/google/gcm/c2dm.html Is the C2DM account used by tmc.openvehicles.com a generic account that can be used by other OVMS servers? I suspect that it is a private account. If so, then push notifications for Android users on independent servers will necessarily require a transition to GCM.

Hi, this brings back cellular usage statistics, using hellocharts lib -- not sure about the previous implementation, there was just a button remaining from that. I chose hellocharts because of it's looks, performance and functionality. I'll try to implement some history data views using it as well -- if there are no problems with the lib. Please test and tell me... https://github.com/openvehicles/Open-Vehicle-Android/commit/a48d3f7bfbe206f… APK: |http://dexters-web.de/f/tw/oVMS-release-3.4.0.apk| Regards, Michael -- Michael Balzer * Paradestr. 8 * D-42107 Wuppertal Fon 0202 / 272 2201 * Handy 0176 / 206 989 26

Leaf info?
by Lee OVMS 08 Feb '15

08 Feb '15

Hi All, I'm Lee, I've just picked up an OVMS unit from Kevin Sharpe, with a view to doing some development for the Nissan Leaf. So I've got a few questions I'd like to ask/clarify surrounding the current state of OVMS on the Leaf if I may. Does the current firmware include all the stuff found during last years Hack-a-Leaf day in the UK? Either way, are there any notes from the day that may help me get up to speed? Or pointers as to directions to head in? Is the "Leaf ODB-II" cable that FastTech now sell different to the old ODB2 left/right cables? Can the older cable be modified into a Leaf cable? I assume the new firmware needs this new Leaf cable? Does the Leaf firmware use the internal GPS from the car or is it better to get an external GPS antenna plugged directly into the OVMS module? What programmer should I buy? The PicKit 2 or the PicKit 3? I've read the 2 is easier to use, but I need the 3 if I'm developing and it's more complicated. Is this still the case? If it's the 2, does anyone have the software, as it's gone from Microchips site (seems to be discontinued). If it's the 3, is there a similar guide to using the 2 covering the extra complexity? Does anyone have a modifiable form of the Tesla Roadster User Guide PDF? As I'd like to convert it into the Leaf User Guide, but it gets a little bit broken when I edit it in LibreOffice. On the same note, the Twizy Guide appears to be a broken link on the site. Is there is decent/easy to understand ODBII spec/site somewhere that is being used to get cribs/pointers to reverse engineering the recorded CANbus chatter? Or is it just knowledge in devs heads? :( Lastly does the CAN Re Tool work OK with the Leaf? As there are mentions Tesla rules in the other files? I thin k that will do for now, more questions as I run into problems! :) All the best, Lee

Android update 3.3.3
by Michael Balzer 08 Feb '15

Hi, some minor rework on notifications: https://github.com/openvehicles/Open-Vehicle-Android/commit/e10a15f850fa3e8… - Dropping duplicate notifications - Fixed notification icon - Immediate display of new notifications if App open - Notification list displays line breaks as sent The duplicates got really bad lately, I think due to multiple test installs. C2DM currently sends the same notification 7 times. I think that may be some issue with unregistering on deinstallation, but as C2DM needs to be replaced by GCM in the near future I just added a duplicate filter in the message processing.
