Re: Connection problem between ESP and STM: Zombieverter

I had an ST-Link (believe it was a clone), but was able to reflash the Zombieverter. Took a bit of finagling, but it's all good, connecting and showing the latest 2.30 update.

Thank Gawd! Now it's time for some serious parameter settings. :)

Re: Connection problem between ESP and STM: Zombieverter

I was able to solve the issue, I found out that I had a connection between TX and RX that some solder flowed on the underside of the pins that caused a short. I cleaned and put in new pins. Everything is good. It was going good. I had a connection and everything, but I made a huge mistake. While I ...

Re: Connection problem between ESP and STM: Zombieverter

I'm still having this issue. Even with new ESP and soldering reflow of the pins.

I have installed a new D1, made sure all the solder was solid on the pads, and still no handshake from the Zombie. I can access the network interface when the ESP is powered by itself, but once on the Zombie, and yet ...

Re: Fiero Leaf

So far it is doing ok. I apologize for the delay, I had some other projects to get done, mainly residential solar projects and etc, and on the Fiero I was spending time rebuilding and refurbishing everything mechanically, from the frame, suspension, braking and etc. That is all complete. I also been ...

Re: Connection problem between ESP and STM: Zombieverter

I'm having this very issue still. ESP will show the network and web interface just fine, when powered alone. But once I plug into the Zombieverter, I get no such connection. I get activity lights and ESP board is powered, but don't know why there isn't a handshake between the Zombie and ESP for me ...

In need of basic instructions to access Zombieverter

I will have to apologize upfront. I've been watching and re-watching Damien's Youtube Zombie videos, along with combing this support site and the wikis, but it doesn't seem to answer a very basic thing that I need help with. That is, how in the hell do I even access the Zombie via the web interface ...

Re: ZombieVerter dynamic pin assignments and more vehicle support

Are you saying that there is a possibility for the ZombieVerter to turn on the heat pump? Like say a Nissan Leaf one on a Nissan Leaf stack?

I know someone on the forum here was working on it. But if that is cracked, that would be awesome.

IVT-S Shut Inquiry

I did a search on this forum, but didn't get a straight answer.

Is it important to have CAN2 for the shunt or is CAN1 just fine?

I ask, because the IVT-S-1K-U3-I-CAN1-12/24 is in stock from a source I can get from, but not the CAN2 model.

This is in particular for a Zombieverter VCU for a Gen2 ...

Re: ZombieVerter VCU Support

On the new release, at least the notes on 1.06V, I noticed this:

"Regenerative Braking is completely disabled for the time being."

Is the Regen Braking being disabled just for the GS300h/GS450h?

Is the Gen 2 Leaf effected by this?

Tesla N/A charging standard

Looks like that Tesla is releasing their design and specification files to the public to push for a N/A charging standard and to allow other vehicles to use their charging and super charging network.

Re: ZombieVerter VCU Support

I think I have figured out just about everything before I jump into buying the Zom VCU board for the Nissan Leaf Gen 2 stack. Really it was just the ancillaries, like water pump and vacuum pump. I think that is figured out. I know there is probably some work being done for read only display or to ...

I sort of figured. Back to the drawing board, although I've seen a couple of DNR gear selectors (round selector and push button) on Alibaba that are 12v.

Choosing a gear selector is next on my list to-do.

I have a Prius gear selector that I'm curious could be utilize for gear selection on the ZombieVerter? This is to drive a Nissan Leaf stack.

As I watched the ZV videos, the Forward and Reverse are triggered by 12v signals. Could it theoretically be programmed to be triggered by 5V hall effect ...

Giving some updates to the project.

CV axles are now done. I was able to utilize the Fiero CV shafts and had them cut and resplined to fit the Nissan inner CV joints, as to make a hybrid cv axles to mate the Leaf gearbox to the Fiero wheel hubs.
