I've just pushed to github the code for v2.5.2. This includes a workable ACC module, as well as a bunch of bug fixes. It also includes a re-working of the cooldown feature in the Tesla Roadster, based on many a hot evening spent in my car with a CAN USB adaptor and laptop. For the Tesla Roadster, I managed to find two new id#100 messages related to HVAC - 0x87 and 0x9A. This is now used by the cooldown feature to track HVAC usage and try to make it work better. HVAC HVAC message 0x87 and 0x9A are enabled with: 102 06 D0 07 00 00 80 00 08 and disabled with: 102 06 10 27 00 10 00 00 00 HVAC#1 B1=0x87 B2=Toutside (outside temperature, celcius) B3=Tmaxbrick (ESS temperature, celcius) B4=Tcoolant (coolant temperature, celcius) B5=Requested cooling % B6=Received cooling % B7= LSB \ Compressor RPM B8= MSB / HVAC#2 B1=0x9A B2=? B3=? B4=? B5=? B6=? [ seems to be refrigerent pressure (scaled with ~/4) but not certain ] B7=TcabinOutlet (celcius) B8=? [ seems to be outside temperature (celcius) ] The build configs are restructured, as previously announced. Currently, I haven't been able to fit either LOGGING or ACC in the V1 module firmware - it is just too big. I'll keep working on this, as it would be good to get at least ACC in that firmware. One caveat: this is largely untested and probably very buggy - which is why I haven't done binary builds yet. I'll test and debug over the next couple of days and then release binaries when I've got something working well. Regards, Mark.
