Get values from slave VESC

Submitted by Snabelost on Mon, 2023-08-07 08:54

Hello,

I'm working on my dual electric motor boat and pretty much everything works except for one thing. How do i get values from the slave VESC?

I have an Arduino that talks UART to the master VESC and then the second is connected using the CAN-bus. I can control both motors perfectly using the following code:

Roll to start

Submitted by Oded Mazor on Sat, 2023-08-05 11:20

Using a Trampa 75/300 in a Kuberg electric motorcycle.

Works very smoothly, however motor will not start from a complete standstill. A little push is all it takes, and than it lift off smoothly.

Using FOC sensored. It's not cogging, just needs a minimum roll to start.

How can I make it start from a standstill?

 

Is there a way to temporarily disable kill switch

Submitted by Elliott Wolbach on Mon, 2023-07-31 23:21

Hello All,

I am using two vesc controllers to drive my robotics project and am using the Kill Switch mode PPM Low as a failsafe on my front bumper sensor. In the event that something hits the front of the robot, the motors will stop, is there any way to temporarily disable the kill switch to manually reverse from the obstacle?

Connecting reverse button to Trampa vesc

Submitted by Oded Mazor on Fri, 2023-07-28 08:09

Installed a Trampa 100/250 in my electric dirt bike.
Would like to add a reverse function. Not interested in brake or Regen.

Plan to choose the ADC mode "current reverse button".

What will be the easiest way, and where do I connect the reverse button to the Vesc?

Brake rpm minimum

Submitted by mcspikesky on Sat, 2023-07-22 22:51

Hello

 

I have been using the adc1 throttle in current, no reverse, brake centre and having the centre as 0

Having a couple of one way cluthes in the system means I cannot regen and if not using the drive it is best for the chain to stop.

The issue being that with the controller in this configuration it makes some noise from the motor at times and I believe causes extra power usage when vehicle is idle

I cannot find any way to disable braking below an rpm?
