VESC Tool

Hello !

I've a old VESC 4.12 buyed some years ago in second hand on internet.

The firmware in the VESC is 2.53

When I connect this esc to my PC, Vesc Tool give me a message "the firmware is too hold ..."

When I upload a new version of the firmware, all is good but the firmware version is the same after reboot. I've read a message on the tool about impossible update after upload a bootloader if another bootloader is present. May be this is the update problem.

Does anybody know how to install the VESC tool on Jetson Nano running Ubuntu 18.04? I downloaded the free version from the website and tried installing it after extracting it, but double clicking on the program does nothing.

hello, I am using current control in my system, and I put the motor max current at any value that is above 10A and the vesc never exceeds 10amperes, I put another motor of another specification and it also reaches a certain limitation that seems that the engine limits the amperage on the vesc, would I have better control of this?

I have a vintage ebikes with mods 

Hello,

I am currently using the VESC 100/250 and the following motor:

ME1507 (ME1905) Brushless 14.5kW Cont. 44kW Pk. IPM Motor 48-100V - - Brushless IPM Motors - MOTORS - EV PARTS (electricmotorsport.com)

Edit: the issue turned out to be a broken hall sensor cable adapter, so trying to diagnose it via software was off topic. Works now!

Please help, no clue anymore...

I have a DIY onewheel project and I'm using Flipsky 75100 Foc 75V 100A and a MPU6050..

After calibrating the IMU everything workes great.

When I power cycle it says IMU not working, no data is comming in.

When I change the loop frequency to something like 850 instead of 800 it works again.

Its like when it boots it forgets to start communicating with the VESC or something.

Help

we update the VESC tool yesterday on our iPhone and android and now we have and error saying 

read firmware version 

could not read firmware version. Make sure that the selected port really belongs to the VESC

any advice ?

I have little FOCer 3.0 

Just wasted 2 hours trying to adjust the second VESC on a Motor with the 3.01 Tool.

 I have updated the Firmware 4-5 times to 5.3 but the Flipsky device didn't swallow on the second VESC. 

I tried switching USB ports and connections but didn't work. 

So after my patience was running out I tried the VESC tool 0.94 and after downgrading the Firmware the VESC Tool asked me if I am on Master or Slave VESC. 

With that I was able to Run my Motors, but it was Frustrating after that experience. 

Hi,

everything is in the title, is there a way with the vesc tool to export in csv the efficiency of the VESC itself. Power injected to the motor / Power taken from the battery = VESC efficiency. Then knowing my motor efficiency at a certain RPM, I should be able to estimate pretty precisely my global system efficiency. These would be super helpful for me, I design farming machines and for one of our project, I have planed to use the VESC to power our machine and measure the power consumption of our machine.

Thanks in advance.
