STM32 MCUs Products

Working on a STM32F103RB Nucleo Board , although not able to understand how to enable SWO pin in order to print the output on the console. The program is being loaded into the board successfully but there is no output shown

Proper standby mode enter and exit

Hello,I am trying to properly implement the standby mode entry routine on an STM32L0 MCU. I have this exemplary minimum working example that does not work as expected:/* USER CODE BEGIN 2 */   HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_SET)...

On STM32H7, can DMA access generate an ECC error ?

Hello,I am currently working with stm32H743 processor.I wanted to know if DMA access can trigger an ECC error or only the core can generate these errors.For example if there is a ram data protected by ECC with a double bit error, would a DMA access t...

hi, we are interfacing EEPROM to STM32L496ZG Nucleo board .but AT24C256 is failing to write data. Please find attached function to write data in EEPROM.We used A0 Device address to write data in EEPROM.Kindly Reply.

int at24_HAL_WriteBytes(I2C_HandleTypeDef *hi2c,uint16_t DevAddress,uint16_t MemAddress, uint8_t *pData,uint16_t TxBufferSize){if(HAL_I2C_Mem_Write(hi2c,(uint16_t)DevAddress,(uint16_t)MemAddress,I2C_MEMADD_SIZE_8BIT,pData,(uint16_t)TxBufferSize,1000)...

Hello, I am connecting a DHT22 temperature sensor to STM32F103C8T6 microcontroller. I am using HAL and reading temperature and humidity data from serial uart, on a terminal on my PC.

Please assist on how to resolve this. because if I deploy in the field it is not possible to be hard resetting every time for data to start streaming.Thank you.

HAL_UART_Receive_IT() returns BUSY and no longer receiving any interrupts

I am continuously calling HAL_UART_Receive_IT(), until i get some specified value in receiver buffer. But after some time HAL_UART_Receive_IT() return BUSY and after that it is not receiving any further interrupts and seems like the code is dead. H...
