Arduino Mini R4 poor performance

[jazzboy]

So the last thing on the agenda is to find motor timing settings to remove the resident banshee haha!

strange sounds haha!!!

Your code above shows calls for motor.initFOC()= and motor.loopFOC(). You can comment those out in Open Loop.

Same code works fine on the Uno and the G474re when flashed from Arduino IDE. The squealing only appears when flashed by PIO with the correct clock settings.

Hey, do you have the option

lib_archive = false

in your platformio.ini?

It’s required.

[jazzboy]

Yes, i did add it. The speed is now excellent but the squeal is definitely a motor timing issue. Have seen it with an esc set to incorrect timing on an rc model bldc in the past.

[runger]

Ah, good.

The reason I asked was because the noise sounds a lot like what you get with a slow PWM frequency, in the audible range. Which is what happens when you run SimpleFOC on platformIO without the option…

[jazzboy]

Yes, you are a genius. I had nested the line. Reflashed and all good. Just trying to get the wow down a bit but totally useable now.

So to conclude this adventure, I say a thousand thanks for all the help. So now there are two viable cards, the Uno and the Nucleo G474re for my turntable projects. The F401re cards are probably useable with an added crystal, but not sure if it’s worth the time.
