VESC Firmware

Current sign varies between motors

Submitted by vadimz on Fri, 2022-08-26 11:24

Observing a very strange behavior running VESC6 with small motors (TMotor MN4010, Faulhaber BX4)

When running idle without load, the motors showing different current signs - positive on MN4010, negative on BX4. Negative current and negative power implies generator mode, which is definitely not the case here - motor is running idle at constant RPM without any external torque source.

 

So any ideas what might be going on here ?

 

Cannot downgrade from beta firmware

Submitted by CasperK on Tue, 2022-08-16 16:56

I've purchased a VESC 6 75V and it came with beta firmware 6.0 (status beta 56). The VESC software complains that I have to downgrade the firmware or upgrade the VESC software. Since there's no newer version of the software available, I need to downgrade the firmware. When I go to the firmware page, it shows all available versions as long as I don't connect to the VESC. But in order to download the firmware, I must first connect to the VESC, but as soon as I do that the list with available versions is cleared.

error firmware BMS

Submitted by Sebastiangeitne... on Mon, 2022-08-15 21:36

Hello, from germany.

I need some help. I own a new trampa board with 2x vesc 6 mk VI and the PCB 21700 IiIon battery pack with BMS. 

I wanted to try the silent hfi and might have made a mistake when changing the firmware. 

Now the regular firmware has been loaded onto both vescs again, but i did not receive live data from the BMS. Both vescs are listed but the BMS is missing under Can Device [BmS (12s7p)]. I hope someone can help me Greetz Sebastian

VESC - HIL / DRV8301 SPI - Problems?

Submitted by mm_iem on Tue, 2022-08-09 12:34

Hello all,

I am are currently building a HIL system. The aim is to have the microcontroller of the VESC in the system and to supply it with simulated current and voltage measurements.

I wondered whether the DRV8301 could be a problem here, since the microcontroller of the VESC communicates with the DRV8301 via SPI.

The DRV8301 will not appear in this setup.

Does anyone know if the latest firmware works even if the DRV8301 is not in the system? So the communication to the DRV is missing?

Hope anyone can help me a bit out here.

VESC Remote - Input Deadband setting causing severe input delay as well as changing deadband

I've had this issue for the longest time where if I plug my Flipsky VX1 remote into my Focbox Unity or my Lacroix Stormcore ESCs it works fine.

This is a video that shows what happens if I crank the throttle wheel all the way to the top and immediately release:

FSESC75200 stopped work after firmware update

Submitted by julia borisova on Thu, 2022-07-07 15:11

I've bought controller Flipsky FSESC75200 and started configuring it with vesc_tool_3.0. Vesc software detects not latest, but compatible firmware. Motor connected to controller rotates smoothly and silently in Duty Sweep Experiment. Hardware version is VESC_75_300_R3. Then I updated firmware to latest version, motor stopped working properly, it jerks back and forth, but does not rotate continuously.

Could you recommend another firmware versions that I can try?
