VESC Firmware

I have tried compiling the latest firmware build, but the .bin file created is 524kb, which is too large to load with the VESC tool.

I have followed the instructions in readme, using Linux gcc

(https://developer.arm.com/-/media/Files/downloads/gnu-rm/7-2018q2/gcc-ar...)

It compiles cleanly.

Hi all, I've been using the forum a lot to troubleshoot but this is my first post :)

I'm an undergrad engineer - 

We've had a lot of problems trying to replicate T motor test data in FOC and BLDC mode

So I've been wanting to use the VESC for use in UAVs due to the potential efficiency benefits as well as wanting to be able to use reverse thrust and record data.

We've been testing these 3 motors in a wind tunnel: AT3520 (550kv, 1000W, 14x7e), AT4125(540kv, 2000W,16x8e) & AT5220 (220kv, 3000W, 19x10e).

I am not sure if the problem I am having is hardware or FW related but I have seen it on three different controllers so I am guessing it is firmware.

During regen braking, when the motor current gets to some critical threshold, it seems that the ESC loses control and is no longer tracking the rotor position or electrical phase properly.

hi all- i just loaded VESC-tool silver on my windows laptop. is it possible to upgrade a maker-x HI200 to v5.03 firmware, and if so, how is that done? i see the Firmware tab in the tool and install new firmware and firmware changelog, but i have no idea whether this vesc will accept the upgrade or how start the download...

i'm running a T-motor U15 off this esc on an ebike, and got pretty close with manual tuning thus far but want to test the latest version. thanks.

.Hey friends
I have a flipsky dual FSESC4
I connected it to vesc and was able to power my hub motors
.But then VESC  told me to update the driver's firmware

after I updated the firmware the engines stopped working no matter what I try, it makes noises that it like its turning but does not move

When I connect the motors and try to calibrate them they move but when I try to choose directions of movement it no longer moves

Hello, I would like to modify the PAS application to make sure that:

1. At velocities below 6 km/h, there is no limit on current, so it can start with high load in a sloped street
2. At velocities higher than 6 km/h limit the current to be sure that the actual output power is less than 250W (power = torque x angular velocity)
3. At velocities higher than 25 km/h, the output is zero

Today i decided to upgrade my vesc app and vesc firmware and the update went well until I powerd on my vx2 remote and the remote is not responsive, its connected to the vesc and it cauptures speed and distance but when i try to use power using the remote it does nothing. im using the 6.6 plus flipsky esc and a vx2 remote connected in uart i have tried everything from updating the FW again and reseting every setting to the old one and restarting the board reseting the remote and nothing helped.

Hi All, does anyone know if its possible to get the VESC to stream its telemetry over any of its UART ports without making a UART request each time you want it? Maybe at a fixed interval?

I updated the firmware, but a message appears that "Your VESC has old firmware".

What should I do?

Hi ,

I have problems with the speed control on bldc sensored hall. The motor at low revs the motor jerks

I am seeing which PID speed output is in current control.

Is it possible that if I change BLDC_SPEED_CONTROL_CURRENT 0 (pid output in duty) the engine improves at low rpm?
