Nissan Leaf + Dev Environment
Hi, I just got an OVMS for my 2012 Japanese Domestic Manufacture Nissan Leaf. I also ordered the Leaf OBDII cable: https://www.fasttech.com/p/1779000 in my left hand drive car, this cable points towards the driver rather than towards the front of the car, I wonder if it's possible to rotate the socket in the car to make the cable point the other way? I didn't have any trouble setting up and communicating via the app or SMS on New Zealand's 2degrees cell network. I programmed the 2.6.5 firmware as recommended by the "Firmware Easy-Install" link on https://www.openvehicles.com/ which turned out to be a mistake. This I think this firmware expects the Car CAN bus but the Leaf OBDII cable connects the EV CAN bus. For a while I thought I had faulty hardware but the soldering looked good and when I took my oscilloscope out to the car and found CAN data entering the PIC microcontroller. It turns out the 2.6.5 firmware is old and you need a later one to work with the EV CAN bus on the Leaf cable. I'm not entirely sure how I missed that, I just checked out the tag without looking at the other tags. I installed http://ww1.microchip.com/downloads/en/DeviceDoc/MPLABX-v3.20-linux-installer... and //bitbucket.org/simbuckone/simbuckbaseproject/downloads/mplabc18-v3.40-linux-full-installer.run (and verified the md5sum matches http://www.microchip.com/forums/m662617.aspx for whatever that is worth) and have a working development environment and have built and programmed master into my unit and everything seems to be working. Thank you all for your work on this project, I'll post again about improving the leaf support (I do embedded development in my spare time). The cars intended for the Japanese market have CARWINGS, but the telematics module doesn't work in New Zealand (incompatible cell network apparently).
Hi Tom, welcome aboard :-) Good to know Leaf development continues, great car! Regards, Michael -- Michael Balzer * Helkenberger Weg 9 * D-58256 Ennepetal Fon 02333 / 8335735 * Handy 0176 / 206 989 26
