Hi @syauqi-alias , welcome to SimpleFOC!
The RP2350 is very fast, and the PWM generation works well.
But unfortunately it has basically the same poor ADC as the RP2040, no real improvements there for low side current sensing.
The problem is that the ADC is quite slow, and that we can’t trigger it well from the timers as we need for low side current sensing.
Even assuming you come up with a scheme to trigger the conversion, converting three phases will take a long time, and this will limit your performance in terms of the PWM frequencies you can use and the maximum voltage you can use proportionally to your power supply voltage.
So unfortunately the RP2350 is not recommended if current sensing is required…
Thanks Runger!, I suppose I will have to switch to STM32 at the end. [insert sad noise]
