Motor control using external microcontroller

Hello everyone,I'm developing a BLDC FOC Control System with STSPIN32F0. I want to control the speed via a host microcontroller. I want to use or PWM and a direction signal or UART. Which of these is the best way to do this? And what is the easiest w...

What is the best way to do functional testing of STC3115 during mass production? One way is to connect a lithium polymer battery to the DUT and do a read back of the fuel guage. Can I replace battery with a DC power supply?

SPV1050 and undevoltage protection

I'm working with the SPV1050 Evaluation Board (STEVAL-ISV020V1) and I'm doing first tests. Undevoltage protection is set to 3.7V. But, what does it happen if a battery is below 3.7V? It seems it is never charged, right? How can I charge a battery tha...

How to read the position value of tamgawa absolute encoder for motor control?

Tamagawa absolute encoder is widely used in servo motor applications. It is a protocol based on RS-485, which can accurately obtain the position value of the motor. Does ST official have relevant interface design? (I noticed that TI has a similar art...

LD39150 footprint Hello, I am curious if any further footprint data or model exists beyond the datasheet. Thanks.

And 3D models or more technical draws preferred.

B-G431B-ESC1 Quadrature Encoder Generation Error

I'm getting an error "Final current ramp value is higher than motor nominal current" when I enable the quadrature encoder option in speed sensing (either as the primary or auxiliary sensor). As per another thread and the schematic, I have reconfigure...

B-G431B-ESC1 CAN Control

I understand from the user guide and previous threads (from last year) that there is supposed to be CAN support, specifically for UAVCAN, on the B-G431B-ESC1 development kit. I wasn't able to find any examples supporting UAVCAN or even enabling the C...
