STM32 MCUs Products

I followed the video instructions to start with idw04a1 on nucleo stm32L476 but i didn't get readable chars in Tera Term VT as shown in the video. I recieve special sign's. My setting is 112500, 8,N,1.

STM32L476deep sleep cannot set pwr_cr1 register bits.

Hi, i am trying to get stm32l476RET6 to deep sleep ( shutdown or standby mode) following mbed examples, but the processors power consumption i measure is not even close at the correct consumption in these modes.At some point, befote WFI() function,...

Synchronizing SPI in STM32F107

Hello,In my project, I connected two MCUs to each other (MISO->MISO, MOSI->MOSI, SCK->SCK). I define a new pin as the CS pin (PORTC.10). But in my receiver the sequence is wrong. Here is my code( For example I send 1234 but I get something else, some...

COMP and OPAMP clock enable missing from RCC chapter in 'F3 RMs

Given similar memory mapping, COMP and OPAMP (where applicable) is bound to SYSCFG in the various 'F3 models. However, there's no information of the clock enable for these modules in the related RMs. It's presumably enabled by RCC_APB2ENR.SYSCFGEN, b...

Hi,Can i use usart instead of uart???RegardsAdrush

Possible to use any I/O PIN for GPIO? (re: STM32, etc)

I'm new to micro controllers (but I have a software engineering background) and I decided to purchase a NUCLEO-F429ZI (STM32F429ZI).There are a LOT of pins on this board (168 I/O pins according to the datasheet!). However, if I just want simple HIGH/...

How can I Test CAN ( MCP2515 ) failure and reason of failure?

I am using CAN(MCP2515 Controller), I need to know the methods used to Test CAN Failure and Build in CAN Test.Methods I tried. 1: Checking Error Flag like Bus-Off Error Flag bit and Passive Error Bit, but due to Arbitration Failure Transmit Error Cou...

Good day! Somehow I can't seem to download files from the ST.com. The STM32 clock configr (STSW-STM32091) is unavailable to me. The Licence Agreement keeps coming back. Tried different PC's and browsers and chache cleaning. What am I doing wrong? Thanks!

STM32H7. The I2C_FLAG_AF flag on I2C4 is always wrongly set.

I have an custom STM32H743 TQFP100 board. I use I2C 4, PB8, PB9 at 100kHz.The code is generated with CubeIDE.The I2C_FLAG_AF flag on I2C4 is always wrongly set and the transmission after adress is aborted.The device sends an acknowledge.Is this an bu...
