Luna BBSHD Ludicrous V2 controller documentation

[bizango]

Is anyone willing to take my Ludi V2 controller and flash it/re-program it? It’s been sitting on a shelf since summer because I tried upgrading the firmware, and it stopped communicating via Bluetooth after it was finished. I probably made a mistake somewhere in the process, and it’s a brick now.

I contacted Luna, and I got some instructions that didn’t help me get any further. They said they can’t do it for me though, and I just can’t afford to spend any more time trying to learn what to do myself. I am knowledgeable in a lot of things, but this just ain’t one of them.

I’ll pay a reasonable service charge for for someone competent to help me get this sorted out. And to make the process even easier I’ll include a pre-paid return label with the package so you can just pack it back up, slap
on the label and put it in your mail box to return to me.

Thanks.

I just wonder how you came to own one of these? Random people can't get them. Many people would love the chance to get their hands on one, so you may not want to let it out of your sight.

Marcos, I will try to get the log from the android , and posted here
And yes I saw it on the android app, turn yellow first and them red and motor stop until get cooler, I pretty sure i need to program the controller better, but let me see how I can get the logs out of the phone and put in my laptop, using Mac , and never have an android .
Still love the controller, i have 2 luna bananas, one 1 of them have the ludi2, and I can see the difference . But I am sure I doing something wrong, because after 2 miles it stop because the temperature

Hi Maro, here are some questions:
1) Was that 120°C?
2) Controller temperature or motor temperature?
3) Can you get a log of that?

I assume you saw 120°C in the android app gauges, that's motor temperature and I think is possible, kinda strange from PAS only but I guess possible if gearing was low. 50Amps for enough time can get the motor to 120°C

So yeah I would need to see some logs to see if there is a problem or not, and you would learn a lot from your own logs to optimize your power delivery as well.

My luvi2 get to hot to fast, I drove 2 miles and controller get to 120 and shut down, even if I only pedal, Any one know what is wrong?? or where I can find the best set up??
Which tempeture you guys get on the controller??
Which is a good average tempeture??

I have a bunch of non-potted controllers here that can't be sold but its up to luna management to decide if they want to distribute them as dev kits or not. Feel free to ask the luna crew though

One side project at a time

I've been doing an stm32 based radio linked remote sensing system for "fun" and stm32 failure analysis for business... but it's likely a good time to go hunting for a ludi2 code development platform - please let me know if you hear of anything

[marcos]

If you go that way let me know so I can send you the latest source code. I've been sloppy and too busy to get the ludi v2 code merged into the official vesc branch, but if a v2 user requests the source code I can (I have to) deliver it.

[AZguy]

Hahaha

... if you do manage it, definitely let me know... I'd love to hook one up and fiddle code

[Tonerider]

Sure wish I could get my hands on one of these controller!

[xcnick]

give me time.

[AZguy]

Does anyone have a blown V2 controller that still communicates?

[brokejaw]

Anyone wanna sell me their v2 controller?

[AZguy]

Oooooo goody... I've definitely been grooving on the STM32's lately, great ecosystem

ChibiOS is new to me but fun to learn new things, even for this old dog...

[marcos]

ah its STM32F405 running ChibiOS :)

Yeah - I would think that your brain sort of knows by feel the pedal cadence but for some reason it's the one field on my display I look at very often. I nearly always pedal so it's mostly for that but it is nice on the very seldom occasions I'm going throttle only... not so much for shifting since I'll run in much lower gears when throttle only with the ring spinning faster than I can turn but when I wish to re-engage my pedaling I can shift to the appropriate higher gear for that.

For me it's no big deal since I've got a GPS with a big beautiful display that has one of the pages with ten user defined data fields along with several other predefined fields and I've got a wireless pedal cadence sensor (and wheel speed sensor, temperature and heart rate) that I can display. I didn't think I'd pay much attention to pedal cadence but like I say I'm oddly drawn to that field more than any other. I almost don't care about speed and the other useful ones are there but not looked at so frequently...

I had to look up spaceballs - that's old... looks like a star wars parody... during that time frame when I wasn't consumed with all kinds of activities/sports I was traveling all the time so no wonder I didn't get the reference... hmmm... maybe we'll give it a whirl on popcorn nite =]
