Driver IHM16M1 burnt pin?

In the lab with a power supply (10V 0.5A) connected to the DC bus of the IHM16M1, the 3 phases of a DC motor, and some oscilloscope probes on the GPIOs of the STM32F302R8 I probably created a short (I don't know how, I deduce).I deduce this because n...

Zero crossing detection

HELLO, Can you please suggest us any mcu having internal block for zero crossing detection in stm32 for 50 - 60hz frequency signals or any slave chips that are dedicated for zero crossing detection. Thank you, Krishna.  

Resolved! USART HAL_UART_RxCpltCallback is not called.

Hello.  I am currently using USART6 by setting RX as interrupt, and TX as DMA in STM32F4.The ST board mostly worked well, however, after some hours (maybe 10 hour), the RX interrupt wasn't called. I suppose that this problem is not related to hardwar...

STM32H7 SPI using common lines for two sensors and DMA

 Hello,I have been working on creating an SPI loop using the SPI callback function to alternate between two sensors that share a common SPI SDI/SDO line. However, I am encountering an issue where the SPI transfer complete callback is triggered, but t...
