STM32 MCUs Products

I am working on ADI-ADXL343 accelerometer on STM32 controller. After few min of communication with I2C I am getting accelerometer idle error. I am unable to understand why this is happening. Please support me on this.

SPI TXE or RXNE never goes to 1

helloI am using an STM32F7 series microcomputer.with SPI peripheralsIf writeable, write to the data register,After that, if it is readable, it is reading from the data register.The image in the code is like below,Writeable, readable loops infinitely ...

SPI Clock goes low when Cable Select does

Hello, I am interfacing with a peripheral where code exists for Arduino, but using it as reference for STM32. The SPI mode is 3. The Arduino code works, so I am attempting to reproduce it's methods for communication. An issue I am seeing is tha...

While setting up the clock, if I set PLLM as 8 and PLLN as 360 , it gives same result as when I set PLLM as 4 and PLLN as 180, so what difference does it makes.

Signal integrity problems with STM32L476 FSMC interface causing emission

FMC is configured to interface asynchronous sram (IS61WV25616, 10ns). FMC 16-bit databus is multiplexed between sram and LCD controller.Data transfer happens using DMA. MCU system clock is 80Mhz. Supply voltage is 3.3VSram and LCD controller is worki...

STM32H745 VDDSMPS Default Configuration?

Hello, I have 2 clarification questions on the default VDDSMPS configuration for the STM32H745:I notice multiple times in the STM32H745xI/G datasheet that "VDDSMPS must be kept the same voltage level as VDD." Similarly, RM0399 also has a note that VD...

For the stm32h743 I use the STM32H7 single-core self-test library. All tests pass, except TM9. Documentation says TM9 implements the test of the Arm Cortex-M7 DSP functions. What can be the reason it fails? DMA is disabled.
