Twizy / 500 kbps CAN lockups
by Michael Balzer 09 Nov '12

09 Nov '12

During my tests I had two times some sort of a CAN lockup, i.e. everything worked except the CAN reception -- was fixed by switching the car off + on. I'm not sure yet what caused that, it (of course) did not happen again since I included a first debug output of the RXERRCNT... I saw the 1 mbps setup does not follow the intrepid timing calculator standard parameters but increases prop delay from 1 to 3 and decreases phase 1 from 5 to 3. A similar change to the 500 kbps parameters though did not work with the Twizy. Do you have any hints on debugging this? My current setup for 500 kbps is: // 500 kbps -- tool recommendation + multisampling: BRGCON1 = 0x00; BRGCON2 = 0xFA; BRGCON3 = 0x07; Thanks, Michael -- Michael Balzer * Paradestr. 8 * D-42107 Wuppertal Fon 0202 / 272 2201 * Handy 0176 / 206 989 26

Last SOC usage range + odometer
by Michael Balzer 09 Nov '12

09 Nov '12

Mark, https://github.com/dexterbg/Open-Vehicle-Monitoring-System/commit/a0fd188a5… contains two change to the STAT SMS I would recommend as a common extension: 1) Odometer status -- very useful if you keep a charging log. (btw, am I blind or does the current Android App lack the odometer info?) 2) SOC current usage min+max: I need to maintain these values for full charge detection and for range calculation during charging. I included this into the SMS for debug at first hand, but now I think this is an interesting info to keep. If you think it's too Twizy specific, here's another idea: As the net modules should not need to know about car specific variables, maybe the new framework could also use some output gathering hooks within the car module, so there's a clean way to add some car specific data to SMS and server output?

Bruce, They look good. I'll try them in the App later. Regards, Mark P.S. Message was too big for the mailing list, and I haven't released, to avoid everyone getting this big message.

Internal GPS now available
by Michael Balzer 05 Nov '12

05 Nov '12

For those driving budget cars without onboard GPS (like the Twizy ;): https://github.com/dexterbg/Open-Vehicle-Monitoring-System/commit/600e08634… Internal GPS integration: - optionally use internal SIM908 GPS instead of car GPS (note: needs GPS antenna) controlled by new compiler switch: OVMS_INTERNALGPS - will poll for GPS data once per second while driving (speed > 0) else once every 5 minutes to be able to trace theft / transportation - reduced Google maps SMS to just coordinates for compatibility with Google Maps App This commit contains no Twizy specific changes, should be suitable for any other car without GPS on CAN bus. @List: I'm a bit frustrated about having to reinvent atof(). I gave up on the lib version, it just produced funny float values (not 0 or something explainable). Found nothing helpful on the web, definitely no type, prototype or linker problem. A new Twizy commit is also there, not much of a change though. Using the internal GPS with a decent antenna works like a charm though, quite accurate and fast. I intend to use the altitude to calculate a better energy usage / range estimation, as the Twizy estimation drops too fast when driving uphills.

Vehicle Images
by Mark Webb-Johnson 04 Nov '12

04 Nov '12

For new vehicles, to get the images into the apps, we need images in a similar size, orientation and layout. The images are: 1] The car front-angle view. 654x302 pixels, high quality PNG format. One for each colour to be supported. The background must be transparent. If you have problems with aspect ratio, try to keep the width the same, and leave space on the top/bottom. 2] The car xray view, 304x606 pixels, high quality PNG format. One for each colour to be supported. The background must be transparent. You should try to keep the wheels in approximately the same position as the attached picture (in particular if your vehicle supports TPMS). If you have problems with aspect ratio, try to keep the height the same, and leave space on the sides. 3] Car map images. 96x96 pixels, medium quality PNG format. One for each colour to be supported. Car must be pointing upwards (north). The background must be transparent. If you have problems with aspect ratio, try to keep the height the same, and leave space on the sides. 4] Name of vehicle type We also need the official name and model of the vehicle type (eg. Tesla Roadster, Nissan Leaf, Volt Ampera, etc). 5] File naming The files should be named as follows: car_<type>_<colour>.png (for the car front-angle view) ol_car_<type>_<colour>.png (for the car X-ray view) map_car_<type>_<colour>.png (for the car map image) The <type> is the vehicle type (e.g.; roadster, ampere, twizy, etc). The <colour> is the official colour name (e.g.; thundergray, crystalred, lithiumwhite, electricblue, etc). Once we have artwork in the correct format, putting it in the apps is trivial. The primary problem is finding artwork of appropriate quality and style, with a transparent background. Regards, Mark.

Debug logging via diag serial port
by Michael Balzer 03 Nov '12

03 Nov '12

I wanted to get some direct debug logging. It took me some time to figure out the diag port only echoes what is sent from the SIM908 to the PIC18, I first thought it tapped RX+TX so I could see the complete communication. Next problem was the modem switches echos off (after COPS I think), so I need to re-enable them at least once in a while. I'm now using this scheme in can_state_ticker1(): #ifdef OVMS_DEBUG // CAN debug log via DIAG port SIM908 command echo: // ATT: could be a problem for running data transfers, // should not be enabled for production/live firmware images! net_puts_rom( "ATE1\r" ); sprintf( net_scratchpad, (rom far char*) "# ERR=%u SOC=%u RNG=%u SPD=%d PWR=%d CHG=%u\r", RXERRCNT, can_soc, can_range, can_speed, can_power, car_chargestate ); net_puts_ram( net_scratchpad ); #endif My questions: am I right with the suspected problem, and is there a better way?

Team Twizy
by Michael Balzer 03 Nov '12

03 Nov '12

Hi everybody, to introduce myself, I'm Michael Balzer from Germany. My regular work is web application and database development, and I'm an electric mobility enthusiast. I fell in love with the Renault Twizy about a year ago and got mine about four months ago. I had been working with some other folks on the german Twizy forum on decoding the Renault Twizy CAN messages (for german results see https://docs.google.com/spreadsheet/ccc?key=0AoKQUT5BY_r5dGJ4c0c2dTBPeGRzMn…) when Thomas Kreisel pointed me to the OVMS about three months ago. I had to wait for the new hardware, but now I'm ready to join :-) I haven't been doing embedded development for some time, and the PIC18 + SIM908 are completely new to me, so please be patient if I ask stupid things. I've just finished a first working can module for the Twizy based on the 1.5.1 code. It's able to read SOC, range, speed and battery power usage. It derives charging states from these and triggers SMS alerts accordingly on charging interrupts etc.. Communication with the Android (market) App is working as well, so this is actually already quite useable... ...thanks to all your great work, of course! :-) Mark, I forked on github as "dexterbg". First commit is checked in, have a look if you like. Now to my questions... Michael -- Michael Balzer * Paradestr. 8 * D-42107 Wuppertal Fon 0202 / 272 2201 * Handy 0176 / 206 989 26

Adaptive Reporting
by Mark Webb-Johnson 12 Oct '12

12 Oct '12

The adaptive reporting now seems as good as it can be. Reduction in cellular data usage is pretty dramatic, and down to about 1/6th of what it was before. Something like 350KB/month (down from 2+MB/month before). Below are some annotated log files from the server for 24 hours with my car running 1.3.8. As well as generally slowing down the reporting interval, and only sending changed records, the code also has re-worked algorithms for linear back-off of data connections. If it loses connection to the server, it will also try to reconnect at the TCP level (if possible) rather than blindly re-establishing the GPRS link, as the cellular providers round-up data usage at the GPRS link level, not the individual TCP connection level. Overall, we try to handle marginal network GSM/GPRS connection areas better. I think this is good to go, so I will build this as end-user suitable firmware v1.5.1 (I live in China, so don't like anything with the number '4' in it), and release later today. Regards, Mark.

GeoSIM
by Mark Webb-Johnson 11 Oct '12

11 Oct '12

Just thought I'd share some results from the geosim (hassle free sims) test that we've been running. We have had the SIM in a roadster on AT&T network in USA, for the past two weeks. Between 27th September and 11th October (15 days), we were billed a total of US$1.39 for data and US$2.95 for SMS. The data was billed at 1.36MB. The SMS charges were for 6 international SMS messages sent by the module on 27th September (kludgy setup with some mis-steps). With my new web-based sms provisioning system that would have been US$0.00. Assuming half the month, the full month data charge would be US$1.39x2 = US$2.78/month, for around 2.72MB. We estimate around 60KB a day (1.8MB/month), so this is a little higher, but the mobile providers round-up connections to the nearest 10KB, so this is to be expected. Yearly, the charges for this SIM should be US$0.00 to setup (or if you do it locally, perhaps US$2.00), then US$33.36 + US$10.00 yearly fee = US$43.36/year. With our new adaptive reporting code in the latest firmware, I'm seeing my data usage go down to about 1/6th. 60KB/day has gone down to <10KB/day. Now, the mobile providers round-up so in poor cellular coverage areas that is not going to be as good, but I think we'll see at least 50% savings. Overall, this seems pretty good to me. We lose SMS control, but the SIM and service itself seems fine. Hopefully the web-based provisioning system should simplify that. We're going to continue the test with v1.5.1 firmware (should be released tomorrow), to see how well the new adaptive reporting algorithms translate to actual usage with the cellular providers rounding up connections to 10KB. Regards, Mark.

SMS Provisioning from www.openvehicles.com
by Mark Webb-Johnson 10 Oct '12

10 Oct '12

I've released the code for SMS provisioning from www.openvehicles.com to the live site. The way this works is as follows: We use a bulk SMS service to send/receive SMS messages, globally. The My Account page on www.openvehicles.com now has the ability to enter a phone number against any of your vehicles. If entered, this is the phone number of the SIM card in the module. A SMS Provisioning form is now provided (reached by the little icon on the My Vehicles page). That form allows the user to enter all the information necessary to provision the module. If the user chooses firmware <= 1.3.5, then the provisioning mechanism will send a REGISTER sms message (to register the global sms provider as the owner), then PARAMS (to configure the module parameters), then optionally PASS (to change the module password, if requested). Each of these messages will result in an SMS reply from the module to the bulk sms service (more on this later). If the user chooses firmware >= 1.3.6, then the provisioning mechanism will send a single AP sms message with all the provisioning parameters. There will normally be no reply to this message. Should the module reply to any SMS messages from the bulk sms service (particularly in the case of firmware <= 1.3.5), then those will be delivered back to us and we will auto-deliver them via eMail to the registered owner. This mechanism is really designed for those using the hassle-free global SIM card we've partnered with. Provisioning it with this mechanism should be very very simple. Open Vehicles is swallowing the cost for these SMS messages. Hopefully it will not get out of hand, and we've got a paypal donate button up there for anybody that uses it and finds it useful. Regards, Mark.
