Re: Buy VESC

eBay, Aliexpress, Hobbyking all stock VESC v4.12s
You can also buy an official Trampa VESC v6 here: https://www.trampaboards.com/vesc-6-com ... 24166.html
But the VESC 6 is rather overpriced.

Re: Remote control for VESC

Having never done this you may need to do a bit more searching around, but I think so.

Re: Remote control for VESC

Usually people set one VESC as the master, this is controlled by the RF remote, the master then controls the slave VESC over CANbus.

Re: UART connection to Arduino (RollingGecko)

I don't have access to my code right now, but I think that's that I did. Try it and see.

Re: Problems flashing

You're not powering the STM32F405.

The critical line is:

Code: Select all

Info : Target voltage: 1.528413


The STMLink is seeing +1.53V on the +3V3 rail. That's not going to work.

Re: High Power VESC

I used the default VESC 6 firmware, v3.37 I believe. which should have the `HW_HAS_3_SHUNTS` already set. Unfortunately by using that firmware I ended up setting my self up for some failures down the line. I'm using 200uOhm shunts, the VESC 6 uses 500uOhm shunts so the current readings are lower tha...

Re: High Power VESC

So I've got it all connected, getting reasonable readings for temperature and bus voltage but the current sensors are way out. I'm running VESC 6 firmware so it should be all set up for 3 phase current sensing but It seems to be subtracting phase 1 and 2 and assigning this negative value to phase 3....

Re: High Power VESC

Another quick update on this. I tried to plumb in a Chinese VESC logic PCB from the 2 PCB variant on to the driver shim. That didn't go well as I had a lot of difficulty soldering wires to the STM32F405. I ended up abandoning this plan mainly due to this but also due to the fact this would limit me ...

Re: General questions

MOSFET vs Diode

MOSFET drops ~0.075V
Diode drops 0.6V

That 8 times difference means you've got 8 times less current flowing to get the same power dissipation.

Re: VESC as multirotor ESC?

I saw it mentioned here or on the other forum. I can't upgrade my Chinese VESCs so I don;t know which firmware versions exactly.
