STPM32 active and reactive measurement results are not consistent.

Hi All,STPM32 active and reactive measurement results are not consistent even after calibration. STPM32 evalboard and ST software are used for tests. We have calibrator as a source. Voltage, current, frequency is accurate but active and reactive ener...

STCH02/3 are able to work without opto feedback? Tiziano

I recently bought STM32 NUCLEO -F207ZG and I want to use it instead of the Arduino for the construction of a smart robot car which includes boost converter (3.5 to 5 V),ultrasonic sensor and H Bridge L298N. How can I connect them ?

Should I use the dc dc boost converter or it is not obligatory and if yes how?

Firmware of STEVAL-ISA172V2

Hi,We are planning to develop STEVAL-ISA172V2 and design customized SMPS.I am unable to find any code. Where we can find the code?what's the procedure to get firmware source or binary from the ST?

I am new to bldc motor control and recently purchased the EVAL6235Q evaluation board. Instead of buying the suggested communication board I am attempting to control by directly manipulating the input pins. Can this be done?

Specifically I am pulling the 'motor direction' pin high, setting voltage reference pins accordingly and then setting the 'enable pin' high. The motor runs but I have no control to as the speed. Can this be accomplished or can this board only work ...

L6562 : Need to understand the functionality of the PFC IC

Hello everyone,I have made the L6562 ref circuit (for 250W provided in the datasheet) on general purpose PCB.I have discussed with coilcraft members, they have said, for initial conditions the resistor divider from rectified mains input will provide ...

stm32g431

on stm32g431 cannt used 2 current sensor isolated how can resolved this problem ?how can tel to motor control team for add this one on library ?

Where can I find an LTSpice or PSpice model for L6591 IC?

When we apply or connect load to Viper26. The output is being dropped from 12 V to 2 V. With current being continuously fluctuating. How do i solve this issue ?

We have designed the board for,Input:Voltage - 200 to 240 VFrequency - 50 HzOutput: Voltage - 12 V Ampere - 400 mA (*Considereing the datasheet, the default float design has been approached. Without the use of any Current Limiting resistor)But unfort...
