PAS function

Submitted by sam.vanratt on Sat, 2018-11-24 14:53

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.

VESC75/300 pre-order, limited volume

Submitted by frank on Fri, 2018-11-23 10:06

The VESC 75/300 is now available for purchase. Benjamin is very happy with the final tests and we can so no reason to hold it back any further. The performance is beyond any expectations. If you have projects that require higher output power do not hesitate to pre-order your VESC75/300 now. This is a limited volume production run of 100 units. First come first served. PCBs will be RED with golden VESC-Logo.

 

no speed feedback in DC mode

Submitted by Jessica on Mon, 2018-11-19 11:17

Hello,

I've been trying to spin a DC motor with a VESC in speed mode. 

I have a position feedback thanks to an ABI encoder but I can't get a speed feedback. In Vesc tool. the ERPM and tachometers stay to zero (with "realtime data" on).

Does anyone know what might be the problem ? 

 

Thanks

Jessica

Fried Hall Effect Throttle Sensor

Submitted by cdw3423vesc on Thu, 2018-11-15 05:16

I have built a power assist device for manual wheelchairs similar to a commercial product called SmartDrive MX2.  I was running my first test the other day and after hitting a bump at speed.  After which the throttle stopped responding.  After I power cycled the VESC the throttle started working again.  Later after hitting the same bump at about the same speed the throttle stopped working again.  This time I couldn't get it working again.  I hooked the VESC to my computer and it runs just fine.  A volt meter across the contacts of the hall effect sensor didn't show any

Newbie - controller/motor not working

Submitted by JLow75 on Tue, 2018-11-13 09:50

Hi all, UK newbie here.

This is my first post, so thanks in advance.

I am undergoing an electric scooter conversion project (similar to what a friend did with excellent results). I have brought all the kit and attempted to bench-test it but I cannot get it working.

Although I am a 23 year time served electronics/electrical technician, I have no experience or knowledge of these controllers, motors or software etc, I'm assuming the problem is something to do with software settings, or incompatible throttle etc. This is my kit:

Encoder over SPI doesn't work on FW3.40: SOLVED

Submitted by john on Mon, 2018-11-12 09:00

Hello,

I've been using a Vesc 4.12 on FW 3.38 using a AS5047D encoder over the SPI port and it worked really well (I had to set the AS5047_USE_SPI_PINS to true in the firmware).

Since I updated to FW3.40, I can't get the encoder to work over SPI, (I made the same modification in the firmware). I don't understand why it's not working anymore, could anyone help me ?

 

Thank you
