Hi, i have vesc from hobbyking hw. 4.12
When i downloaded vesc tool i must flash new fw (3.38)
After flash my vesc in vesc tool show fw:4.10 and i cant complete motor wizard. In motor detection i have: detection failed and motor is dead.
After this i write faults in terminal, this is output:
Hello,
I have problem wit sorting out how CAN Bus is working in VESC. I'm trying to controll current and brake current in both VESCs connected with CAN magistral.
Master (device with connected receiver) VESC Tool Setup looks like this:
Slave VESC Tool Setup looks like this:
Hello,
If I send a PWM signal of 700 microseconds pulse length to the VESC, the VESC tool shows a length of 1000 microseconds. If I send 1700 microseconds, it shows 2000 microseconds. Is this a known bug?
Can anybody reproduce this? Using a FOCBOX with FW 3.38 and the newest VESC tool.

Hello. I have a strange issue with my VESC 4.12. I have been using this VESC with firmware 3.34 up to 3.38 now and I am noticing something wrong about the phase current limit.
In my configuration I had set the phase current limit to 100A. After doing a data log with my VESC during a ride, I noticed that the phase current was being limited at ~68A. The battery current limits are working fine, but the phase current limit is off for some reason.
Hi there,
i'm using the awesome VESC in my electric scooter with the following setup:
throttle potentiometer on ADC1
Brake Button between PPM and GND
esp8266 on RX/TX as a wifi bridge to stream data to my smartphone
As App i'm using ADC no reverse brake button in current control mode.
Everything works great, but i also want a Pushbutton for cruise control. Is this already implemented and i do not find the info, or is a cruise control button not provided with the described config?
On the A200S, every time I try to set my motor type to DC it bricks my unit and I have to reflash the firmware. I am using a modified version of the 75_300 configuration. Also how are you supposed to debug the firmware? The guide is very old now.

Hello,
Is 3rd harmonic injection for FOC already implemented in the Firmware?
It allows a 15% higher motor voltage and thus higher speed for a given battery voltage
without the disadvantages of field weakening.
See:

Furthermore it can help to reduce the speed ripple for quad-copter applications.
Hello,
I have a vesc 6 to use it on an electric bike. I wanted to add an option to configure only the max current and the max ERPM by UART in order to control via a raspberry Pi.
I just started by adding the lines in commands_process_packet function, in command.c :
// check if the code comes here
send_buffer[ind++] = packet_id ;
commands_send_packet(send_buffer, ind);
Hi!
I'm building some vesc:s but having the problem with that the vesc isn´t booting and are not detectable by usb.
Fairly certain that my soldering is correct since I can read the chip and program it with verification.
Programed with 3 different OS and have hade the same result every time. Have even tried the files from this with out results http://fishpepper.de/2017/10/31/tutorial-initial-flashing-a-new-born-vesc/
Any ideas?
