STM32 MCUs Products

I have nucleo H7A3ZI-Q board, i was trying to load one example to the controller. The IDE asked to update the ST-Link , Afetr updating target is not detecting. Tried in ST utility tool also, the ST Link is getting detected and the target is not.

STM32L1 GPIO pin configuration - Current leakage on pin with open-drain setup

SetupI have an STM32L151 mcu(application processor) and on its PB5 pin I have a peripheral (SARA-N3) connected. The requirements for the peripheral are that the pin is configured as an open drain output and is only used to pull it down for 1 second. ...

I am working on STM32F103C8T6 with ADC and UART . I am getting the problem in send ADC value to UART ASCII Code and Problem in receiving from UART ASCII code to numerical value like 0 to 255. Please Help me.

I'm using theNucleo STM32L152 and I want to remap PC13 on timer 4 IC2. But on the ICR register, I can set all the bits except bit 17 to select timer 4 (I can set it 16). I configued PC13 as Alternate function AF14. Do you have an example working correctly

Auto-polling mode with octal memories is not functional.

Hello everyone,I made a custom board for our design, a STM32L4R9VI and an ospi memory MX25UM51245G are integrated on this board. There is a MX25LM51245G on STM32L4R9I-disco board, but it is not in stock, so I chose this 1.8V version MX25UM51245G. The...

STM32H743 - SPI-DMA timing problem with slave select

Hi everyone,I have a problem with a bidirectional SPI communication. I am using the HAL_SPI_TransmitReceive_DMA function for all my communications and my project is loosely based on the STM SPI example. I have now noticed a problem with my communicat...

Receive/Transmit UART data using DMA

Hello,I use with:- Nucleo-H743ZI2 -STM32CubeIDE ver 1.6.0-MCU Package ver 1.9.0I made loopback between PB14 & PB15 , the loopback work i checked it without DMA . I try to send data from buffer and get the data using DMA but it is not working.Thank's
