HAL Delay () function does not work with HAL_UART_Receive()

Hi everyoneI'm having this problem while using stm32L073RBT:When I use HAL_UART_Receive() only it seems normal, but when I use HAL Delay () after or before HAL_UART_Receive() the program freezes,Knowing that I did not enable any interrupt!!Thanks

UART Interrupt Issue and Interrupt Generating

Hi, I am using UART receiver in interrupt mode. After couple of hours it stops working(Only the UART Receiver Interrupt stops working, TX and Main loop keeps working). The handler function is too big and this is probably why it happens. If I were to ...

I have a STM32F769I-EVAL board. I am trying to look at the demo and see if the chip can do what I will want it to do. However it doesn't seem to be seeing either Micro SD Card. Is there something I need to do to the board in order for this to work?

Serial NAND flash support on STM32F412

Hello,anyone please help me to select the right flash IC for my application.In my project i am using STM32F412 main controller. we collect the data and stored to flash. once data collection is completed it will send to cloud.We need 8GB flash for dat...

CAN Rx Interrupt cannot be reactivated due to LOCKED using HAL_CAN during Tx in Background

 We use HAL_CAN_Transmit in the application. If during the call of this function a CAN Rx Interrupt happens, in the function void HAL_CAN_RxCpltCallback(CAN_HandleTypeDef* opt_canHandler) the HAL_CAN_Receive_IT fails as the CAN is is still HAL_LOCKED...

I2C is sending only n-1 bytes

Hello,I'm using a F301K6T6 based board. When communicating over I2C the first RX/TX works fine but the second TX is starting with the second byte and thus sending only n-1 bytes.While debugging recognized that `HAL_I2C_Slave_Transmit_IT()` is setting...

Parallel transmission using GPIO and DMA (like AN4666)

Hi,I would like to send parallel byte data from STM32H743 using DMA, e. g. using Port G0...G7, using a timer to define the cycling (e. g. TIM3.CH2).For STM32L and STM32F4 this is described in AN4666 I think. I did this already on STM32F4, there it se...
