Newbie Help - ADC input

Hi All

I am attempting to build a friction drive E-bike, but am new to Brushless motor control and am at a loss as to why my set-up isn't working.

I'm using a Flipsky FSESC6.6 with 6354 190KV Motor, and the generic Hall throttle from Bangood.

I've had some intermittent success getting the motor set up through the FOC wizard. However I am unsure if FOC is relevant to my application?

My biggest challenge is with the throttle. I believe I have it connected correctly in to the ADC1 connector, however I'm getting no feedback through the tool other than a constant floating voltage of around 1.4V. From what I have found online, I should be using Duty cycle settings, I've tried a quite a few times with both the manual set-up and the app wizard to no avail.

Any help or suggestions would be greatly appreciated as I feel as though I hit a wall, but also expect the solution to be a simple one.

Cheers! Nick.

Hi Nick,

I may be able to help you if you havent had any succcess with this yet. Could you post a photo of you're wiring?

 

Cheers

Can you try connecting a potentiometer to the adc. make sure u use the VCC and not 5V. using 5V killed my adc input. Connect the pot and then use duty cycle. you should see a smooth transition in speed.

Hi I know this is an older post but thought I’d still try. I’m having the same problem with my ADC e-bike throttle not responding to my Flipsky 6.6 VESC in VESC Tool input wizard. Tried manual and wizard to set it up. Did you end up figuring it out? Thanks

most of e-bike throttle do not operate supply voltage under  4.5v, so it must be powered at 5v.

its output usually sink to gnd with a resistor (4k..10k), and it gives 1..4v output, a simple voltage divider to 3v max could be diverted to vesc. mapping should be done under vesc-tool

I have sourced a quadrature hall sensor which according to the TDS needs 4V at least, have not yet tested it though.

On the other hand 2 of my throttles from China works fine with only 3,3V.
