Help with nucleo board and pca9685 servo board

Hello everyone,I came here looking for help : I'm doing a project for an intership where i have to create an hexapod robot basically from the ground up, with particular interest in the electronics and programming part.As a main microcontroller, we ar...

Problems with STSPIN32G4. False overcurrents errors, and gd_nfault occurs. Bad soldering process?

Hi, we are facing a strange problem with your MCU + GD combo - STSPIN32G4. In general, about 60% of soldered ICs are not working properly, we test on the default firmware generated for EVSPIN32G4 and we get error "64 overcurrent" and / or gd_nfault a...

Investigating the Cause of Empty Measurement Fields in EVAL3PHISO Kit's STPM005 Software

I am attempting to establish a connection between the EVAL3PHISO kit and its accompanying software, the STPM005 GUI. To power up the board, I am utilizing a USB cable connected to my laptop. The illuminated green LED on the kit verifies that the boar...

The datasheet of the powerStep01 says: After each Byte the CS Pin must be toggeled, but in the diagramm the CS Pin is toggeled between these four bytes. What is correct? Are there additional failures in that datasheet?

I want to know the FIT rate of following IC L9908TR.

Why would I use a STM704 instead of a STM806 battery monitor?

Program in my STSPIN32G4 is not executed while i turned controller power off and on, how to check if the code is in flash memory

Using the STEF12H60MPUR; question about dimensioning RCS and RCL when current limit fixed via RCL.

Dear Sirs,I don´t know how to calculate RCS or RCL. For example, IOUT is 2.9A and ILIM is 3A, but what are the values for RCL and RCS?Very thanksfull for help.Regards,Jean-Paul

STNS01 CHR pin keep toggling(fault condition)

I've tried 3 circuits for testing, with various 1 cell LiPo batteries(300mA~ 500mA)STNS01 CHR pin keep toggling 1Hz when VBUS connected in.(with or without battery)And it is not charging batt. at all.VBUS 4.92V, Batt 3.8V
