User Manual MCSDK documentation

Dear MCSDK users, The full MCSDK documentation is embedded in the Motor Control Workbench tool. Refer to Workbench tool > About > Documentations > Documentation.This document provides: Introduction: Includes startup guide links for MCSDK, HSO featu...

MCSDK 6.4.0 is out!

Dear MCSDK users, MCSDK version 6.4.0 is now available: Download It here. This version of the new Motor Control SDK 6 series (X-CUBE-MCDSK) provides mainly FOC and 6Step improvements, here are the main changes for this version: Motor Control Features...

Board Manager documentation is out !

The documentation of the Board descriptions format is now available on Motor Control Boards Description Wiki page, this documentation is compatible with MCSDK versions from 6.1.2. Board Descriptions are used by the ST motor-control workbench to enabl...

How to write a Motor control post to get a response quickly

In order to have a quick response to your forum posts, the best way to ask the question is:- Give the version of the MCSDK used. - Say if the problem concerns a tool (MC Workbench, Motor Pilot, Motor Profiler, etc...) - Provide picture of tools inter...

100W protected sink with dead battery and multiple power sources

My application will manage multiple power sources (battery, DC, UCPD) and have a TCPP01-M12 protecting CCx lines. With this configuration the STM32G4 could already be powered by DC or battery, but must be able to negotiate 20V on VBUS. I want to avoi...

STM32F103C8T6 , Timer1 PWM channels have different frequencies ?

STM32F103C8T6 MCU is used for controlling a brushless DC Motor. Firstly I used bipolar switching for Inverter Circuit. TIM1_CH1 ,CH2 ,CH3 pins used for upper mosfets of each leg and TIM1_CH1N,CH2N,CH3N used for lower mosfets. When I want to set the p...

What are some techniques for minimizing the startup time of the firmware? I want to go from 0V applied to the mcu, to be up and running as soon as the supply voltage rises to the absolute minimum voltage needed to power the mcu (1.7v?)

Turn off the pwm timer if running 100% duty cycle

How do I generate code for custom board?

How do I use the Motor Pilot 6.1.0?

I have a motor running in the V1.1.3 Motor Pilot.Now what?I built a 6step controller of a hi-revving, low inductance/resistance motor. It compiled in STM32CubeIDE and is pushed to the board.I started the motor pilot and successfully connected to the ...

Resolved! When I write to a L6474 Register, I do not get the same result back.

A very simple example of this is Register 0x16 Which is STEP_MODE register. It says Bits 3 and 7 are always 1. I write 0xCC to the 8 bit-register. When I read it, it reads as 0x4CWrite Param is just the ADDRESS sent. Read Param bit 5 is set to 1. So ...

How does the SEQUENCER prevent race conditions for STM32WB?

In this post, it was mentioned that the Sequencer is recommended to avoid race conditions especially when entering low power mode. Are there any specific examples of race conditions and how the sequencer avoids it?On the other hand, in AN5289, the do...

How can I allocate port D2 as the Encoder Z pulse input?

The "documentation" suggests that any IO port that can act as an interrupt is usable, but the motor control workbench only has selections for A2, A9 and B10, all of which are used for other peripherals. The document suggests selecting a "dummy" port...

L6474 communication works but motor is not turning

I have connected various stepper motors to multiple x-nucleo-ihm01a1 shields on a NUCLEO F466RE.The code is the same as ST's X-CUBE-SPN1 (i just changed the function names) In main() after SPI has been initiliazited at 2MHz at mode 3, I set the regis...
