STM32 MCUs Products

The specified A/D datasheet performance shows a typical SNR of 69dB. Measurements on the EVM give values of 81.8 dB. Does this family of parts usually run that much better than datasheet values?

What is the thought of putting two processors in parallel sharing all but one pin. And only one is active at a time depending on the state of the one pin at reset?

I have a system that needs to run for years. But is in a place where it cannot be maintained. The desire is to have two processors, one running, and one in backup. The second can be powered down, or powered up, but in lowest power sleep mode. If a pr...

IRQ from SPI DMA Rx Complete before end (too early)

I use an SPI interface with Rx and Tx DMA to transfer a 22 byte buffer from a spi slave. Chip select is handeled withLL_GPIO_ResetOutputPin(TDK_nCS_Port, TDK_nCS_Pin);set to high again to end transfer I wanted to use:// SPI5 - IMU TDK Rxvoid DMA2_Str...

backup SRAM (available in the lowest-power modes)

The backup SRAM cannot be accessed in the (normal) Run mode ?

1.board-NUCLEO-H743ZI2 . we are dumping code into flash externally through USB .for that we are making boot0 pin high and low manually.is it possible to make boot0 pin high and low in software. I don't have access to change boot0 pin in MX.

we are not able to change boot0 pin in MX configuration. for other input output pins we are able to change the configuration but not for boot0 pin.Thanks in advance.

FDCAN between two STM32H747 MCU boards

I would be interested in implementing a FDCAN communication between two STM32H747 MCU boards. I have implemented communication on a single board in External LoopBack mode. However, I am having problems understanding how to connect the two boards. Do ...

STM32f407-Discovery : Configuration of I2S full duplex mode for using external audio codec

Hi, expert,I'd like to use external audio codec with STM32f407-Discovery.STM32 is master and Audio data is receved and transfered using I2S3 Interface.Below is connection between STM32F407 and Audio Codec.And I used I2S DMA for transfer and receive d...

Keyboard scanner library sought

I'm in search for a library of routines that allow for scanning keyboard matrices with or without diodes in various configurations. I've heard it exists for Arduiono but I'm pretty sure there is such for the STM32 series too (my target is an STM32F10...

STM32F105 contact with flash through SPI ,the MISO pin has bad waveform

When MCU（stm32f105） communicates with flash（W25Q64JVSSIQ）, it is found that the waveform of MISO pin is incorrect. Please tell me why this problem occurs。

Controlling a Nucleo-L476RG Board Wirelessly

I am starting a DSP class project that will be auto-adjusting blinds using the Nucleo-L476RG board. To start off, I am wondering how it is possible to control the Nucleo board wirelessly with an android phone. I am aiming to control a stepper motor ...
