VESC PAS and ADC App - How does it work?

Hi guys,

I managed to get my ADC working fine on "ADC" and "ADC and PAS" app.

My PAS Sensor is working on "PAS" but not on "ADC and PAS" app.

Does it have to be wired differently there or is "ADC and PAS" not meant to work as both throttle and PAS sensor input in the same app?

Would appreciate any help you have!

Hi,

It seems to me as well, that the PAS function is still very limited, and the combination of ADC-PAS is not really working. IIRC it behaved like a simple ADC control.

If you check the committers and search the forum you can see, that there are attempts to use the PAS but there is no further official support yet. Benjamin noted with the addition of LISP programming to VESC, that it makes easier to make a custom codes, such as custom PAS, but it is still a qute hard thing to do for a non-programmer..

Hi,

surprisingly I finished of a Pedelec Bike Project using the VESC MK6 and was yesterday at the same point wondering why this double function doesnt work. But anyhow, the PAS works freaking awesome!!! So smooth and comfortable. Many friends tested out my bike (daily commuter) and nobody can feel a difference.

How/where did you connect the PAS sensor? I assume all the sensors are the same and just vary with the magnets. Im also interested in using that in tandem with ADC torque sensor.

Spintend Single Ubox 75V100A, GMAC 10T, T9N torque sensor, 48V

PAS with ADC works only when You are using brake switch, at least that was problem in my case. I have flipsky 4.2 VESC and I have throttle on ADC1 with brake switch on ADC2 and PAS sensor on TX and RX, everything works.

But I have a problem- I need reverse. In tool I can select ADC_CTRL_TYPE_CURRENT_REV_BUTTON_BRAKE_ADC , but I cannot find what pin is assigned for reverse in this case. Maybe somebody have any idea?

Hello
I am trying to run Trampa VESC MK6 Firmware 6.2 with pedal assist and throttle together but doesn't work.
In PAS app does work perfectly but after switching to ADC and PAS app doesn't?

I am running the same setting with
U-box100 and does work perfect.

What am I missing here any suggestions will help.

I've yet to see a reliable way of getting a 3 wire pas to work.  Unless there's lisp code out there it'd be easier to order a quadrature pas and wire it to the TX/RX/5V/GND wires on the main COMM of whatever interface being used.  At least that's how I got it to work on a Flipsky 75100 V2.  Just thought I'd rehash this thread as I hate seeing threads with important questions I've had go unanswered/ignored, which lead me here. I'll try the brake switch as Pas doesn't seem to work by default when "ADC & Pas" is selected in the App cfg.   

 

On a side note, it'd be nice if standard 3 wire pas support could be implemented as they're so ubiquitous. I was lucky that my mid drive had a quad/torque sensor built into it.

hello everyone i am to wondering where to wire in the pas sensor but i do believe i have the answer to both of them working at the same time its the adc app it doesn't release the controller completely you can test this for yourself in vesc tool when adc is enabled you cant turn the motors with your app or keyboard anymore

hi guys i'm new in the forum and in vesc, as for the other guys i need to setup a PAS on my Flipsky 75100 Pro V2

googling around it looks like i need to buy a 4 pin PAS sensor or i'll loose the PAS + throttle option, plus it looks like i have to dowload a script to activate this funcion

can someone help me with some links where to buy the 4pin PAS in europe? it looks like this kind of sensor is not easy to buy on this sied of the world, plus where can i find the good script to implement into vesc to make the PAS to work fine?

i'm following this guys https://www.youtube.com/watch?v=lMT3JHWMbMk mainly
