VESC Firmware

Hello all

Not sure if this is the right place but here goes.

I have recently purchased a vesc from ebay in the uk. I have just tried to connect it and instantly got a message saying firmware is too old, please update with a programmer.

I thought this was the latest model. I am confused and dont know how to resolve this. I am using the new vesc tool and https://www.ebay.co.uk/itm/183433522210  link to vesc ive purchased. 

hi

i have some test mini vescs based on 4.12 hardware but they are with 2 and 3 miliohm shunts

can someone compile latest vesc 4.12 firmware for 2 and 3 miliohm shunts?

thanks

Hi guys,

I downgraded using vesc tool 0.91 and bam it all works again. I repeated and switched between the two to verify. Happens on both my vescs, both my bluetooth adapters and both phones. For whatever reason data isnt being sent on the latest firmware. Im using HK vesc 4.10 and genuine keyes hm-10s. Anyone any ideas why?

I edited the FW and compiled a 100% throttle limit VESC6. Then I ran a motor at 100% throttle and it seems to run fine. However, the current measurements in VESC-Tool are all wrong. The average current at 100% throttle is very different from the average current at 99% throttle. And the sampled data makes no sense at all. Here on the left is the sampled data. On the right is oscilloscope traces of the phases showing the vesc is indeed running at 100%.

Since the generator usecase seems pretty common I wrote a custom app for that:

generator_app.zip

Uzip it to get generator_app.patch (unfortunately ordinary text files are not allowed here, so I had to zip it) and apply to a current firmware (current = 3.40, but older should work too) with

I see that in BLDC control there are two parameters for switching frequency: max and min. Is that because the PWM frequency is adapted on the go?

Can I put max and min the same value to keep a constant frequency?

Hi all.

Apologies if this is a known issue or has been talked about before. 

Hi all,

I have two problems with a motor using FOC.

I'm controlling via PPM mapped into duty cycle. It's a small motor (max 300W) with KV=380.

The first problem is that giving 0.050 ms increments in the ppm (in a range 1-2ms ie steps of 5% of the total range) it happens that the motor stops completely as in the following figure.

Hi,

I see the maximum Switching Frequency I can set is 150k, but can it really work at that frequency the driver?

My goal is to run at 68k, can I test it without problem? I'm using a relatively small motor (max 15A @24V) for multicopters.
