Resolved! STM32 Reset pin duration

Hi,We are working with the STM32G491 board and intend to drive the NRST pin using an external device. Could you please confirm the minimum low-level pulse duration on the NRST pin for it to be recognized as a valid reset by the MCU?

STM32H7 reading FLASH causes Hardfault

The chip is H743. After performing a erase operation on a page and resetting it, when I read the page again, the debug page shows that the erased page is 0xAA. As long as I read it, I will enter hardfault. Have you ever encountered a big shot,

Resolved! MCU power consumption issues

I would like to ask about the current load. I expect to use three sets of SDADC, SPI, and USART, all of which will use DMA for transfer and operate at a frequency of 11000HZ. The clock will use an external 12M crystal oscillator. I estimate from offi...

Resolved! STM32G0B1CE schematic review needed

Hi everyone,I’ve designed a schematic based on the STM32G0B1CE microcontroller. Since there’s no official development board available for this specific MCU, I used the schematic of the STM32G0B1RE Nucleo board as a reference, along with the STM32G0B1...

Resolved! STM32N6 Internal SMPS Reference Design

I've been trying to find examples of the STM32N6 using the internal SMPS however, other than trying to reverse engineer the Nucleo or Discovery boards, there doesn't seem to be much literature available showing this.Ideally (for cost and board layout...

Resolved! STM32U5A9 2D GPDMA Repeat Counter not working

Hello, I'm trying to use the repeat counter of the 2D GPDMA peripheral. However, when I configure this with CubeMX and run it, I can see that the BRC register is always at zero, while the BNDT register is set to the correct value. I've stepped throug...
