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

Industry Attempting To Stop DIY EVSE

Some interesting developments in the UK with an attempt by the UK EVSE Manufacturers to prevent DIY EVSE; http://speakev.com/threads/industry-attempting-to-stop-diy-evse.1615/ I intend to fight this but suspect it might be something for OVMS to watch closely.

Firmware 2.6.5
by Jack West 19 Mar '14

After upgrading to 2.6.5 (V2/TR) I am experiencing some trouble using ACC. Is there a revised document detailing commands and usage? I suspect user error. I downloaded 2.6.5 from Git and compiled myself. ACC PARAMS would not set an ACC location until I used the ACC HERE command. After successfully loading PARAMS and enabling ACC the charge appeared to start as planned. However the charge did not complete as it seems the car overrode the ACC command with a previously defined timed charge. It looks like virtually no charging took place even after the car's timer should have started. Possibly unrelated but maybe relevant is that the car would not start after unplugging charge cable. Charge port door had to be cycled and then car would start. I also notice what appears to be garbage in PARAMETER 15 (COOLDOWN). No cooldown commands have been issued and the garbage looks very similar to data in ACC location#1. No other ACC locations have been defined. Jack

Compilation issues, OVMS.X/v2_RT with Battmon and Cfg

Hi, Willing to use Michael’s last commit featuring "save/load sevcon profile » commands, I pulled the latest code and went to MPLab X IDE v2 (c18 v3.40). Alone it compiles fine. But if I add OVMS_TWIZY_BATTMON and OVMS_TWIZY_CFG (to a duplicated from V2_RT_Production conf) to the definitions I end up on a : "/Applications/microchip/mplabc18/v3.40/bin/mplink" -p18f2685 -w -m"build/memorymap" -u_EXTENDEDMODE -z__MPLAB_BUILD=1 -u_CRUNTIME -l "/Applications/microchip/mplabc18/v3.40/bin"/../lib -o dist/Copy_of_V2_RT_Production/production/OVMS.X.production.cof build/Copy_of_V2_RT_Production/production/UARTIntC.o build/Copy_of_V2_RT_Production/production/crypt_base64.o build/Copy_of_V2_RT_Production/production/crypt_hmac.o build/Copy_of_V2_RT_Production/production/crypt_md5.o build/Copy_of_V2_RT_Production/production/crypt_rc4.o build/Copy_of_V2_RT_Production/production/led.o build/Copy_of_V2_RT_Production/production/net.o build/Copy_of_V2_RT_Production/production/net_msg.o build/Copy_of_V2_RT_Production/production/net_sms.o build/Copy_of_V2_RT_Production/production/ovms.o build/Copy_of_V2_RT_Production/production/params.o build/Copy_of_V2_RT_Production/production/utils.o build/Copy_of_V2_RT_Production/production/inputs.o build/Copy_of_V2_RT_Production/production/diag.o build/Copy_of_V2_RT_Production/production/vehicle_twizy.o build/Copy_of_V2_RT_Production/production/vehicle.o build/Copy_of_V2_RT_Production/production/vehicle_none.o build/Copy_of_V2_RT_Production/production/logging.o MPLINK 4.40, Linker Device Database Version 1.3 Copyright (c) 1998-2011 Microchip Technology Inc.

PS: Twizy ravaged friday night, they took everything but the OVMS, breaking the glovebox, including half of the smartphone holder making it useless even for the stealer… cool :( -- Julien (JaXX) Banchet
