VESC Firmware

Hi everyone

I have looked all over and failed to find command and telemetry information in a convenient package. I dug through the VESC 6 firmware and extracted what I believe are the correct formats. 

I am looking for somebody to glance over my PDF and see if the formats look roughly correct. I will get to test  it next week to verify but if I have made an obvious error, it would be good to learn it now.

Thank you.

Hi Frank and Benjamin

I am using the integrated current sense amps in the DRV8301 in addition to a seperate low-side current sense ampin order to measure all 3 phase currents. I accidentally swapped the SNA and SPA traces on the DRV8301. TI had actually swapped the names of these pins for the newer DRV8353 and I made the mistake of assuming it was the same for the older DRV. So now I'm looking to compensate for this in the code. Does anyone know off the top of their head where in the code I can simply change the polarity of the measured current for these phases? 

Hello,

Can anyone please explain the algorithm used in sensorless FOC control? How is the position of the rotor estimated? Where can I find the algorithm for sensorless FOC control?

I am looking to implement a new absolute encoder via the hardware SPI interface.

For encoder details see: https://www.rls.si/eng/orbis-true-absolute-rotary-encoder

What is the recommended way to implement that:

1. Add to the  "encoder.c" and "encoder.h" code
2. Add the code in a separate file included/referenced in the "encoder.c" and "encoder.h" files
3. Create a custom application

Thanks,

Toma

Hello, 

After really long time I have finally completed Paltatech v.02 logic board.  And I have troubles getting firmware for it.

I was following this guide: https://github.com/paltatech/VESC-controller

But I can not find any mention of paltatech v0.2 hardware in HW selection in conf_general.h.  Just axiom and other hw versions.

Hi all,

i have a custom app, to control the motor for my underwater diving scooter. This scooter has a trigger button for run/stop and a rotary encoder to set power from 10% to 100%

At the moment i control the motor just with mc_interface_set_duty(0..1)

Is this enough ? or do i have to set something more ? maybe current ? all other apps do so much more :)

Thanks

Georg

I was riding my skateboard the otherday when it suddenly lost power and wouldnt reboot. It now only displays a blue light when on (no green like my other working vesc). From my research I found that this could perhaps be a firmware or bootloader issue so I have been trying to redo it using a raspberry pi running openocd and the GPIO pins connected to the vesc.
