Using CubeMX 5.3.0 to autogenerate a sample STemwin example set of code for TrueStudio seemed to work well. It was created choosing the STM32F429 Disco board and adding the STemwin graphics options...no customization of any settings was done. The p...

Hello,I'm looking to use the STM32F429 to output data to an SVGA display. The supported video formats for the display are shown in the image below. The display is actually a monochrome variant, so color is not relevant as the RGB lines are tied tog...

Hello,Using the MCSDK monitoring tools, we have been able to drive our motor up to 6000 RPM with no issues when unloaded. However, when we put the unit under load, then the desired and achieved RPM deviates somewhere around 4000 RPM. The system is ...

Hello,We have used your MCSDK successfully in a custom BLDC design and it is working well. We have some conditions however when we are reducing speed on a large inertia and this causes an overvoltage spike. The MCSDK faults on this (we have it set ...

We are using the ST MCSDK, it is very helpful. In MCSDK/MCLib/Any/Src there is a function called STM_FaultProcessing. It is auto generated by Cube. We have one line we want to add to it that turns an LED on alerting the user to a problem. This wo...

This person also had the same problem. Fix is to reduce the LCD clock frequency (reduced mine by a factor of 4 (/2 to /8 on last divisor). Works now.https://community.st.com/s/question/0D50X00009yGS3SSAW/cannot-run-a-simple-hello-world-application-...

Using the same setup but generating for Keil MD V5 produced the same results (except that stopping debugging did not stop the flicker in this case).

Hello Giuseppe,I've looked at this 20 times. But 21 was the charm! The op amp is fine. But we had a 3 milli-ohm value in the code generator, yet a 2 milli-ohm shunt resistor. The 2 milli-ohm is listed as 3W rating on the schematic so the optical ...

Thank you Giuseppe.

The problem was resolved, but not clear why this was an issue. The "NOMINAL_CURRENT" define in pmsm_motor_parameters.h was generated from the MCSDK with a nominal current of 16A. This motor, at 4100 RPM was only pulling 6A. But this was the limiti...
