Upon seeing this, woah. So cool
This kind of progress and development is so great for all of us.

Profiles are great if you’re letting a relative noob try one of your boards. I setup a full power profile for me and the initiated, and built a noob profile where I limit the top speed to 20mph and set the accel/brakes to 60% so that they don’t instantly mash the throttle and get bucked off or thrown off balance.

Exactly this.

Yeah. Last time I tried to mess with them was for a buddy to try one of my boards. I haven’t written them off or anything. The need just doesn’t come up much… Unfortunately I can’t get my old skate buddies pumped about these

Nice work, it connects again BUT now I have some strange stuttering which might be because I use both UART ports (Metr+VX2 receiver). I only had time to check it really quick, more details tomorrow :slight_smile: maybe it was becasue I didn’t reboot the VESC after the Metr FW update.

Is it worth trying HFI on HW4.12 or there is no significant improvement to be excepted on the 2-shunt design?

Although I’m not sure this FW is 4.12 compatible yet.

It may not ever be, it was stated above this works best with three shunts AKA VESC 6.x+ based stuff

HFI is used at low modulation (duty cycle/speed) 3 shunts really becomes beneficial as modulation is increased and the sampling window for current measurements decreases. So HFI will work equally well on two shunt designs.

Phase shunts do offer a benefit of doubling the sampling frequency which makes it easier to move into the inaudible range but we need to do some tricks before it’s possible to run 45 khz pwm sampling v0 and v7 without maxing out CPU.

So, should i run motor detection to get hfi optimally set up or just choose hfi from the menu?
Also, any guidelines on configuring it ?

So who’s tried this on focbox? This HFI thing might actually make me try something other than 2.54 :slight_smile:

I will try it tomorrow :+1:

Edit: I need a new soldering iron, will report back in a day, sorry

Edit 2: Played around with it a bit, 1/3rd of the time it tries going in the wrong direction; doesn’t feel any better than just regular sensorless FOC currently, but will play around with it some more later. Gonna watch that tutorial Deodand made :slight_smile:

Let everyone know how it goes, if this works on v4.12 reference boards it breathes some fresh air into them.

Made a video tutorial, kinda long but I wanted to be somewhat thorough:

hopefully this video becomes obsolete soon and the algorithm can just configure itself :slight_smile:

Does HFI work in BLDC mode?

nope, in bldc it only shows hybrid, sensored or sensorless. The HFI setting only appears in FOC mode

gonna be honest, only started using foc to have nicer sensor integration. with the unsensored motors i was always pushing first and using bldc. now that the foc HFI is there, I’ll probably just be using foc now purely for that, both hfi and nicer sensor integration
