How is it done, in details? 

Thanks.

Hi, 
I'm re-initializing the hall sensor table for a motor. I got 99-161-126-26-59-199. Now these are supposed to be evenly distributed on 0-200. Would it make sense to improve the running of the motor a little by by taking a 0-33-67-100-133-167 and rotating it (adding a 0-32 constant to all of them) until it matches the measured numbers as closely as possible? I have done that and set the hall table to 28-62-95-128-162-195 now (in the correct order). 

Is there any real benefit in using 3 phase shunt resistors vs 2 other than high current sampling mode? I see in code that in different vectors it use different shunts pair but does it help?

I am currently using all 100v rated components apart from the current shunt amplifiers which only go to 80v. There are no >80v shunt amplifiers avaliable so I need to put something around it to 'float' it at the common mode voltage.

I think this is the most useful app note on the issue http://www.ti.com/lit/an/sboa198/sboa198.pdf

The simplest method is to just add a resistor divider with precision resistors. So I might try that out and see just how bad it is.

I'm using analog brake signal with my HAL sensor brake leaver.

I was wondering. Is brake always REGEN or is there also a active brake? (So always negative current or is there a positive current component too?)

I know there is a handbrake feature that actively holds the wheel. But that is something else of course. But it got me wondering.

Thanks

Hi,

I bought three months ago two VESC from DIYELECTRIC SKATEBOARD (https://diyelectricskateboard.com/products/torque-esc-vesc-bldc-electron...) 
to drive my drone motors. I flashed both of them with Vesc_Tool 0.87 and they worked very well and I was pleased with their performances.

Hi,

Is it possible to increase motor temperature in mainstream VESC Tool to somewhat around 200C? I think 120C is to low for hardcore users. 

Tried to recompile VESC tool from github with no success (missing bluetooth, serial port and some other libraries...). Maybe there is some tutorials how to setup QtCreator? Tried following recommendations from Documentation section.

Hi,

Having some issues with ABS_OVER_CURRENT and can't find "Configurable FOC current filter" in VESC Tool. Can someone give me a hint where to search it (feeling like a newbie :D)?

Hello everyone,
         I am currently working on desgining a VESC 6 pcb,  I want to know some information about the VESC6,  for instance PCB dimension, trace size, via size.

Any help would be appreciated!

VESC 6 - With NRF (EU CUSTOMERS) Premium Silicon cables, XT90 connector & 3.5mm Gold plated Bullet Connectors for Underboard Battery tray

I am new to using VESC. I wanted to attach a potentiometer to my VESC to control the speed of my motor. I know that I have to connect it to the GND, ADC and 3.3V pins but I am lost as to how should I program it on the VESC project program? Any help or guidance would be greatly appreciated, or even links to another forum that may lead me in the right direction. I am just lost as to what I can use to get this working. I am using a 25V power source with a 270V motor and a 500K potentiometer. Thanks for all the help.
