Adc.....mapping 3

I have 2 vescs connected with can bus and single power supply. Both the vescs have same firmware and i am using similar bldc motor. I tried controlling the two vescs using the vesc tool via usb, but it didnt work and i can only run one motor at a time. So after a lot of search i found that i can may be use arduino via UART port to run both the vescs. 

I tried running both the vescs individually using arduino and it works fine, but my doubt is when i connect it to the master vesc, do i have to connect only the communication wires or GND as well? 

Hi all, 

Whilst lying in bed it occurred to me that it might be possible to use both adc channels connected to the one analogue joystick but wanted to ask if anyone can confirm if my idea would work. 

Hello!

I am using MKS and FlipSky 50A VESC to control 350W 24V DC motors. I would like to have some special algorithm of current limitations. For example, when motor is idle (DUTY CYCLE =0) I would like to have much more current to start motor under load for few seconds , then I can make it lower. The same for changing direction. When DUTY CYCLE cross "0" we set MAXIMUM CURRENT, after few seconds, we set it to regular current limit.

What do You think, does it make sense?

How to write such lisp script? Can somebody help me with it?

Updated my firmware on my trike ,what do I need to adjust or tweak for my sensorless take offs to be smoother bit lumpy at the moment 

i was looking into the vesc 6 schematics when i saw this part not connected to the main mcu or anything, so, what is it for?

Hi there,

Does anyone know of any production VESC controllers that currently offer/feature an isolated CANbus? I am planning to use a bunch of these in a multi battery system and so isolation is key, I haven't been able to find anything myself. 

Thanks in advance for any tips.

How to setup my VESC with AD2S1205 and use FOC with A,B,NM signals?

New to Vesc tool. Just had my xenith take dump after a capacitor fell off that lasted about 5 years. Brand new stromcore setup with the voyager 2 transmitter, (yes I switched the imput wires) first run about a half a mile frim the house the brakes went out and the ESC wouldn't turn on after. I couldn't get anything out of it into the vesc tool on my phone and then I downloaded the computer app and neither will connect. The company sent me a new stormcore 60d, everything went good setting up until the phone app proceeded a firmware update to adjust furthur settings.

Hey guys! I am having wrong sensor readings. Temperature MOSFET 1 and 2 are oscillating around 200 Celsius degrees, and MOSFET 3 is constant at 25 degrees. The VESC is at rest and is not hot when touching it. I get Temperature MOSFET Error (MOSFET temperature maxiumum is set to 190 Celsius degrees in VESC Tool).

How can I disable in the firmware MOSFET 1 and 2 ? There isn't such an option in VESC Tool so i need to customize firmware, or a change in VESC Tool to add this option?

I am using Maytech 75/300

Thanks a lot !
