I have a design which uses STM32G431C6T6 (LQFP48). In the MCSDK, it is possible to select only between STM32G431RB (LQFP64) or STM32G431CB (UFQFPN48).Is it somehow possible to configure/hack the MCSDK use some different MCU? This LQFP48 version of th...

I'm using motor control hardware very close to NUCLEO-G431RB with X-NUCLEO-IHM08M1 3Sh. It has only a bit different bus voltage and current feedback scaling resistors so I was able to spin the motor it with the motor profiler. The results were quite ...

Oh, you're correct. I have the same scaling with value 65535, but it comes in later in my code. Good that this worked out for you (too).

Hi, you can try scaling yourself, using the BusVoltageSensor_Handle_t's internal variable. Something like this: float V_d = (float)PQD_MotorPowMeasM1.pVBS->AvBusVoltage_d; float volts = V_d * (ADC_REFERENCE_VOLTAGE / VBUS_PARTITIONING_FACTOR); I...

You're welcome!And to be precise, the insulation of the motor wires was the thing that melted away.. Copper did not melt, but due to the resistance of too thin a wire, the copper just got hot enough to melt the insulation. And this resulted in a shor...

Oh, by the way. I suggest that you measure the phase voltages too. Or I mean, use the API functions to request the phase voltage. You probably get amazed that the readings are pretty low compared to battery voltage... It will give you some viewpoint ...

I have not done the torque unit conversion at all. But that seems to be covered already..When you program the torque ramp, you request the phase current. Not average (nor RMS whatsoever) current. So with your A, B and C, you get the phase current whi...
