I have fitted the largest motor I could find to my fiskars stay sharp push reel mower to drive the reel only. Using a vesc v4 to drive the reel and using an Arduino to give me throttle on a switch. Working in pid mode perfectly.
Hello everyone,
I am currently working to implement CAN bus control of multiple VESC's from an external microcontroller host since it is the most robust communication between them IMO. So far I have been able to send commands to each VESC with the extended ID frame and successfully execute commands such as set_current() and set_duty(). The next thing I would like to do is receive data from each VESC about voltages, currents, RPM's, faults, etc.
I've installed my Bluetooth adapter no issue and connected my vesc to it through discoverable devices, but when I try to connect my vesc to the vesc tool it just tells me "Could not read firmware version. Make sure that selected port really belongs to VESC." or "Could not autoconnect"
I have an off-road board that uses two parallel setups. Two batteries, two motors, and two VESC's. The batteries are 6S. It's been doing great. Recently I added Hall sensors inside the motors and changed the VESC's to run in hybrid mode (sensored at low ERPM and unsensored at higher ERPM). Not FOC. It ran nicely with the new sensors for a few days; but today one of them fried. My buddy was just cruising around a level parking lot at very low speed. No idea what went wrong. But it looks
Hello,
I'm trying to get the simple UART example from SolidGeek arduino UART lib to work (on an arduino micro)
https://github.com/SolidGeek/VescUart/blob/master/examples/getVescValues...
The sample (and lib) does compile and upload just fine.
However, all I get is "Failed to get data!" message that seems to happens when there is a hardware communication problem.
VESC firmware 3.4 (i used the latest VESCT_tool to configure them).
I'd like to add reverse to my board, but I don't want to control it directly via the throttle channel. I'd prefer a separate input to the VESC that tells it I want reverse mode, and then I'd use the throttle channel to control the speed in reverse. Does anyone know if the VESC has any such input?
Thanks very much!
In my application, I need the motor to apply a small stall torque in some cases. The stall torque is needed to overcome some friction in the system. RPM of the motor at that working point is obviously zero or very close to zero for some limited time.
Hello all VESC users
as I seem to be the only one using the VESC on a bike I'd like to know what I/O pins are still available for such a use? None seems predefined afaik apart form the ADC ports.
I've done a analogue PAS to throttle function build with two OpAmps, I'd like to get it into the digital age and code.
I use the VESC4 board, but when I connect the board and the computer by using mini USB, my computer can not recognize the USB. Could you please tell me how to solve it?
I am confused a bit: torque control mode controls the current (and hence the torque), but what about duty cycle? Does that control the duty cycle of current, supplied to the motor?
Thanks!
