VESC Tool

Please help, no clue anymore...

I have a DIY onewheel project and I'm using Flipsky 75100 Foc 75V 100A and a MPU6050..

After calibrating the IMU everything workes great.

When I power cycle it says IMU not working, no data is comming in.

When I change the loop frequency to something like 850 instead of 800 it works again.

Its like when it boots it forgets to start communicating with the VESC or something.

Help

we update the VESC tool yesterday on our iPhone and android and now we have and error saying 

read firmware version 

could not read firmware version. Make sure that the selected port really belongs to the VESC

any advice ?

I have little FOCer 3.0 

Just wasted 2 hours trying to adjust the second VESC on a Motor with the 3.01 Tool.

 I have updated the Firmware 4-5 times to 5.3 but the Flipsky device didn't swallow on the second VESC. 

I tried switching USB ports and connections but didn't work. 

So after my patience was running out I tried the VESC tool 0.94 and after downgrading the Firmware the VESC Tool asked me if I am on Master or Slave VESC. 

With that I was able to Run my Motors, but it was Frustrating after that experience. 

Hi,

everything is in the title, is there a way with the vesc tool to export in csv the efficiency of the VESC itself. Power injected to the motor / Power taken from the battery = VESC efficiency. Then knowing my motor efficiency at a certain RPM, I should be able to estimate pretty precisely my global system efficiency. These would be super helpful for me, I design farming machines and for one of our project, I have planed to use the VESC to power our machine and measure the power consumption of our machine.

Thanks in advance.

Hello !

I'm developing a C++ driver with a Qt interface to send inputs to my fsesc through can bus from py PC in order to command a DC motor and to read the current from the esc .

NEED TO SET UP FOWARD REVERSE AND ALSO REGEN. i CAN GET FWD REV ok BUT NOT WITH REGEN. USING TWO OF THE NEW 100 VOLT 300 AMP CONTROLLERS.

HOW DO i DO THAT?

This is for an e-bike custom build. I am using a bbshd motor and a Spintend ubox single controller with a fully charged 52 volt 19 ah battery. I am very new to this technology and did not know it existed until a few weeks ago. When I am running the motor setup I am getting this error message. I'm only using the hall connections and phase wires for now. Nothing else is connected. I would appreciate if someone could please help troubleshoot this issue with me.

VESC Tool errors on startup on my Windows 10 x64 system. It looks like a QT message. Here's the whole thing...

Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples -1, swapBehavior QSurfaceFormat::DoubleBuffer, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile QSurfaceFormat::NoProfile) .

I checked my RX PPM output pulse width using a scope (well, two different Picoscopes). It has a min to max range of 1.1 to 1.9ms

However, the Real Time app reports this as 1.324 to 3.147ms

That confuses me, any explanation people ?
