Is there a quick start guide for EVSPIN32F0251S1

For the device STEVAL-ISV006V2 how can change output tension from 5.5V to 2.85V

We do not find in documentation formations about R4 R10 and R2 adjustments ....and how can be used.

Motor rotation become backward/negative direction problem

I use FOC+Hall and try to start in forward direction by speed mode as below:MC_ProgramSpeedRampMotor1(200/6, 200) MC_StartMotor1()but the motor become backward directionI found at STC_CalcTorqueReference() function, the return value SPD_GetAvrgMecSpe...

HALL_MAX_PSEUDO_SPEED question

HALL_MAX_PSEUDO_SPEED questionat HALL_TIMx_CC_IRQHandler() function, how come the "if condition" become TRUE, then assign HALL_MAX_PSEUDO_SPEED value to pHandle->CurrentSpeedI found that the motor is not rotated, but the HALL_M1.CurrentSpeed value is...

SRC0CS25D fail

I have 3 boards that shares same power input schematic from battery power. I use SRC0CS25D to control power up of board. First two boards works great.The third board works, but the 3 sample which i used for debug purpose, after a while they fail to p...

IHM02A1 stepper motor driver with red led (FLAG signal) always ON

Hi,I've connected a IHM02A1 expansion to drive two stepper motor on a Nucleo-F302R8. I've followed the user manual UM1964 to setting up the example both in the standalone version and in the UART version. I can't achieve to have the motors move and I ...

Two application questions for powerSTEP01 - how to externally power the core correctly and how to drive brushed DC motors?

1. Power supply to the core logic: What is the right way to do this such that the Vs motor supply can be turned on and off while leaving the logic running? The datasheet leaves much to be desired (which are input power and output power pins is confus...

How to use the VIPER222LSTR IC?

I want develop a power supply board for my STM32 project.For my power supply board I want use a VIPER222LSTR converter but reading the datasheet I realized that some resistors and capacitances values not are specified.How to use the VIPER222LSTR IC?T...
