STM32 MCUs Products

Nucleo144 H745ZI-Q (rev C) EXTI interrupt continuously firing for user button no matter what I do unless I disable the interrupt

As an exploration into MCUs I'm doing everything as close to "deserted island" as I can and using assembly instead of the HAL and all that, but I'm having an issue. I was following in general this tutorial and just setting the registers as needed, bu...

I know there a unique ID for each STM32 MCU, but I was wondering if there is something similar for each discovery board? I mean can I identify the board (not the chip) by a unique ID?

INTERFACING STM32 AND ARDUINO UNO V3 SHIELD

Hi Team I am trying to interface ARDUINO ans STM32H7B31 I have both boards and i have studied the document that says the arduino connections CN10 CN11 CN19 CN20I hope it need and interface/shield to to connect as both the boards have the female conn...

HAL_QSPI_TxCpltCallback function is not being called for HAL_QSPI_Transmit function

But yet it is called for HAL_QSPI_Transmit_DMA function? Do I need to configure the autopolling with the QSPI_AutoPollingTypeDef structure for the callback to be called with the HAL_QSPI_Transmit function?

Why does my LSCO output for my LSE have a delay in matching my LSE input.

I am developing on a STM32L4 product and was having issues with the CSS shutting down my LSE signal. I found this problem in the errata and turned the CSS off, but it forced me to look closer at the signal my LSE crystal was providing (using the LSCO...

hi all, i want to know the number of cycles for addition, float addition, shift, multiplication and float multiplication of STM32F103REY help me please

Is DMA peripheral to peripheral data transfer possible in the 32L476rg MCU ?

HelloI am currently working on a project that requires pushing data directly from a uart rx pin directly to an SPI device (an external SRAM) tx pin One way to do it, is by using DMA , unfortunately most Stm32 MCUs do not offer a peripheral to periph...
