Status of STEVAL-EDUKIT01?

I just assembled my EDUKIT01 and getting my feet wet. I downloaded all the available PDFs, files, etc. from https://www.st.com/content/st_com/en/campaigns/educationalplatforms/motorcontrol-edu.html and also from the https://sites.google.com/view/ucla...

How to make STUSB4500 negotiate PDO2 automatically?

My schematic is exactly as shown on page 26 of https://www.st.com/resource/en/datasheet/stusb4500.pdf with an ESP32 connected to the I2C pins and a BQ2057WSN downstream on Vsnk. However, on connection to USB-C the chip negotiates an explicit 5V powe...

I have purchased STEVAL-IHM038V1 from Mouser , but I am unable to find any Firmwere with it , to study the code I want your support for fast development of BLDC ceiling fan application. I have C2000 series controller application software knowledge .

Resolved! Hi, I use the STSPIN820 to drive the stepper motor.There are three issues about the STSPIN820.

1. Is the value of the current in coil A or coil B still IREF*sin( 90° *n/4 ) or IREF*cos( 90° *n/4 )after the pluse on the step clock pin (STCK) dont trigger any more?2. Is the torque still keeping after the pluse on the step clock pin (STCK) dont t...

Hello, I have a question about the component : VND5T100AJTR-E I am trying to get his "Mean Time to Dangerous Failure" but I cant find any data or way to calculate it. So could you provide me some information about it ? Thank you very much

Resolved! Are the pins of this high side driver ( VND5E160AJ-E ) correct ? The datasheet show that 2th input pin controls 10th and 11th output pins but it is not correct. The 3th input pin controls 10th and 11th output pins. Is this IC reliable ?
