Configuring STEVAL-SPIN3202 to control a brushless gimbal (6 step commutation - STSPIN32F0_Uart example)

Hi,I am trying to do six step BLDC commutation on STEVAL-SPIN3202 to control a gimbal motor https://www.robotshop.com/ca/en/ipower-gbm5208h-200t-gimbal-motor.htmlI am using the STSPIN32F0_Uart example under the following sw packagehttps://www.st.com/...

Is it necessary to use heat dissipation on PowerSTEP01?

I´m using powerstep01 in a new design. I need to keep a little holding current on the step motors (3 motors).I noticed that the chips get hot even the board is on open air. I´m afraid that when mounted inside the product cage, the chips get very hot....

Setting register in L6470 and then reading it back returns zeros.

I'm sending commands to a L6470 on a prototype board, which is essentially just a breakout board. The commands are being sent from Python (stspin.py library) from a Raspberry Pi. I am recording the SPI bus transactions via logic analyzer, connected t...

Hi, I am using SCT10N120 in my design, For Vibration and Shock simulation, I would like to know the weight of the component. Could you please provide the weight information if you have ? Regards, Sakthivel

How to build STEVAL-SPIN3201 firmware with makefile?

For a project I need to use SPIN3201 but it's required to be build with make. Therefore I wrote a makefile and when I try to compile the project, some functions are missing. I have found the function prototype in a .h file but I cannot found the func...

I want to use the STPM32, and STPM33 to measure current with Current Transformers but not measuring voltage. Have these devices some feature similar to the STPM01, which have the Single wire meter mode when there is not available voltage information?

All the reference designs includes both Current and voltage measure. If I need just current, could I work with some fix voltage value ? Thanks

I can't get good accuracy of current value at three-Shunt resistor current sensing topology during low speed or climbing hill

We using found three-Shunt resistor current sensing topology when using FOC to control motor, but we found that the current value is not accuracy during low speed or climbing hill situation , is there anyone know how to fix this issuethanks

Hii Can any one suggest me MOSFET for 800V whose voltage drop is very less. My application is to switch ON the coil of 220VDC , current that coil can draw is 6A , Switching ON the coil is for fraction of secs

Can the ST1PS01EJR programmable Switching Regulator change voltage levels on an active MCU?

The use case is a L4xx MCU that needs to write to an SD card, most of the time the MCU sleeps and checks sensors. The ST1PS01EJR can be configured to start up at 1.8V and then the MCU could change the output to 3.3V write the data then change back to...
