Resolved! STM32H7 Synchronous USART receiving problem with DMA

Hello, in my project I need to read an encoder that clocks out data with clock burst. For this I decided to use UART with clock generation and DMA. (I also mixed up RX from one UART to another , but this is not a problem if request happens at the sam...

Pulses on PC13 pin of STM32F103C6T6

The LED connected to the Blue Pill board on PC13 pin blinks after power up. Just to check the pulses on that pin, probed and seeing the attached pulses. Why are these pulses generated? I haven't seen any data about this in any of the documents? I did...

Resolved! STM32G0B0 ROM Bootloader USB DFU

Hi,I have been able to use the option bytes to configure the Nucleo-G0B1RE to jump straight into the ROM bootloader on powerup and I can see the DFU on Cube Programmer, however on our target board with a G0B0 using the same user option bytes settings...
