VESC_default_no_hw_limits

Hi Im new to VESC.

I have purchased a Flipsky VESC 6.6 with the firmware (VESC_default_no_hw_limits).

I am trying to interface using B Vedder's (VESC® Tool 1.08).

I am getting an error message saying firmware not compatible.

I need to know if I am using the correct version of B Vedder's VESC tool? or will I have to change the firmware on my new VESC ( which I am reluctant too)?

Any advice appreciated

Thanks

VESC 4.12 firmware 3.38 flash back to firmware 2.18

Submitted by Arm007 on Thu, 2019-04-11 08:30

Hi all,

 

i want to buy a vesc 4.12 with the firmware 2.18. But i only can find the vesc 4.12 with a newer firmware (i.e. firmware 3.38)

Well, my question is:

If i buy a vesc 4.12 with the firmware 3.38, can i flash back the vesc to the firmware 2.18? Is that possible? And how can i do that?

 

I did not work with the vesc in the past. So i am very new.

 

Thank you.

New Motor Simulator (Signal Injection)

Just as a heads up, we created a pull request to add our virtual motor support code.

With our virtual-motor branch you can engage a virtual motor using the vesc terminal and start playing with it.

More info and fancy screenshots in the Pull Request

Maybe someone finds it useful and can't wait for Benjamin to review it.

 

No USB with latest VESC FW on 4.12 hardware

Submitted by chris1seto on Thu, 2019-04-04 04:01

Hi,

 

I have a Flipsky 4.12 hardware based mini VESC. I did a git pull on my clone of the bldc firmware repo, and then changed the configuration files to uncomment the following:

> #define HW_SOURCE "hw_410.c" // Also for 4.11 and 4.12
> #define HW_HEADER "hw_410.h" // Also for 4.11 and 4.12

When I load the firmware, however, I have no USB VCP. 

Any ideas what might be wrong? Did I miss a source config step? If I use hardware 60 I do get USB VCP, so I know the board is fine.

 

High Power Configuration with Resolver Feedback

Hello,

I'm currently trying to develop a 60kW motor drive for Emrax 188 motors. I'm in the very early stages of the design process, building a basic block diagram and researching specific part numbers. I've taken a majority of my inspiration from Marco's 150kW VESC design.

PPM Over limit settings.

Hi All,

I am currently using the VESC in a robot application which uses mixing to control the steering. The issue I am having is on standard remotes the mixing method basically makes the corners go beyond 100%. This triggers a failsafe on the VESC as the pulse is out of range causing the robot to stop.

I am trying to modify the app_ppm file to mitigate this however I am unsure where this is contained.

From reading the source I thought this section would be responsible for limiting ranges in servo_dec.c.

Sine Wave Frequency

Submitted by speed3r on Mon, 2019-03-04 14:11

Hello folks,

 

I'm new to this forum and before asking my question I'd like to say that this project is amazing.

 

I am planning to control a PMSM with 5 pole-pairs.

So if I want to have 20000RPM (for example) I'd need a sine-wave of (20000RPM*5pole-pairs) / 60seconds = 1.666 kHz right?

I was wondering, where I can find information of the maximum possible sine-wave frequency (or the therefore needed pwm-frequence of the fets).

Does anybody have a link / hint for me ?

Thank you!
