Hey guys!

I have the following problem:

Last year (November) I build with my pupils e-longboards at school. Now 7 month later we want to reactivate the project.
But now I have the problem to get the error "no firmware response" when I connect the VESC with my laptop. For some seconds there is the sign "connected" and then the error follows. 
I also tried different cables and it is the problem with every board (strange).

Maybe my software is to old (also downloaded in November last year) to work with the firmware?

HI, 

I have an E-bike motor  with hall sensors, and I just detected and installed FOC mode. A little testing shows that sometimes it doesn't start. As this is just for a test, that is fine with me. 

I then made the motor turn and got a sample from the "sampled data" tab. What suprisded me is the quality of the BEMF that was measured, and the wrong-ness of the FOC position estimation.... 

Hi, 

I'm a bit disappointed by the range of motion and feel of the typical e-bike throttles, and I'm wondering if designing my own throttle around these components below wouldn't give me the best results in terms of fine control of acceleration and braking.  

Do you receive notifications by email when there is a new post? I have seen that someone else had this problem but I do not know if it is general

To get notifications in some way I have tried adding it to tapatalk but it seems the forum need a extension installed to work with tapatalk

So my question is How do you know that there are replies in a thread?

Hi everyone,

I am trying to control two VESC modules with a Raspberry Pi 3, however, I can't seem to connect them. 

I started with just one, and when running the command lsusb (I'm working on Ubuntu Mate 16.04.2) the RPi doesn't seem to find the VESC.

The VESC I am using (a version 6) I already tried on my Windows 10 laptop and there it worked fine. Its firmware is updated (3.38) and I even did the motor setup and was able to control the motor with the arrow keys.

Hi there,
today I tried my first VESC build, and I´m starting to get the hang of it except a problem I have when braking.
I´ve tried everything to solve it, but nothing has worked. The VESC is a MAYTECH VESC v4.12, and it throws an error when braking.

The error is the following:

Can anyone explain the 3 throttle curve settings in he vesc tool to me 

I'm designing an Electrostatic Field Mill - a device to measure electrostatic fields. One part of the device is a small rotor spinning. My plan is to use an re-purposed hard drive motor to do this and now I'm looking at VESC as a possible ESC. It will probably be an overkill, but it is important for the measurements that the motor produces as little electrical noise as possible.

I ordered a VESC hardware version 4.12 and I want to control it from another microcontroller. 

For this purpose I need current and speed measurements from the VESC, over any bus possible. Unfortunately my controller can't do CAN so I'm stuck with UART or I2C.

Is there any documentation how to get started on the busses? I am very proficient with CAN but haven't worked with the other busses that much.

Thanks!

Hello,

I tryed to switch vom a PPM remote to a one using UART (Photon remote).

I got it working but then tryed some settings in the VESC-Tool.
And after i used the Input Setup Wizard my master VESC dosent show up over USB anymore....slave VESC still works fine via USB.

On both VESC´s are thesame LEDs on.
How do i debrick my VESC?

I hope somebody can help me with this, thx.

Edit: also when i try to connect via USB the VESC_tool stops working

Edit, Edit: Works again after removing the Photon remote
