Hi all, I am connecting to my Sevcon Gen4 2 using an Arduino, Seeed Studio Can Bus Shield, and TwizyCfg (with some slight modifications). I am going through the CANOpen OD and trying to find something that will let me output/export all of the settings. I found some stuff on the 0x1010 (STORE)...

I got it all working now that I got a working can bus shield! Now for the crazy CANOpen learning curve.

See my last post. I'll try it out when I get the new one, but even if I had a good board, I'd expect the readsdo(0x1018,0x02) to work, at a minimum, so that the returned value could even be checked against the Twizy version. I think I spent so much time thinking I was doing something wrong...

Well, crap. After searching for a while, I ran across a few forums with people with similar issues. Most of them seemed to be discussing bad boards or soldering issues. Then, of all places, a 1-star review on Amazon was discussing how his CAN Bus board came with NO jumpers connected. I...

According to the Sevcon Calibration manual, it can autodetect the baud rate by listening to the heartbeat. From the manual: This implies, to me, that there has got to be some initial commands that can be sent before logging in. So, in a master-slave configuration, where the master is...

I don't actually have a Twizy, but my EV (EcoSpin Raptor) uses a Sevcon Gen 4. I am attempting to use Twizy config code with some minor mods. I am not even able to send a read-only command. I've also tried other CANOpen arduino monitors. At a minimum, I'd expect some command to work, namely...

Hi all, To start, I am completely new to this world. With that said: I have a 3-wheeled 48v EV that uses a master-slave Sevcon Gen4 configuration (S2 36/48V 275A AC Motor Controller). The company that made it is out of business and I am trying to connect to the CAN bus. I have an Arduino UNO...

Hi all, First post, so to start off, I have been reading/searching here and everywhere for possible answers to my question(s). I am completely new to BMS's, don't have an EE background, but tinker enough that I can hack my way through stuff. Anyway, I'll try to make a long story short. My...
