Hello,I have a Nucleo-F439ZI as SPI master connected to four Nucleo-F030R8 SPI slaves.Initially, the SPI communication was working perfectly fine. But after a while, the master received only zeros on MISO line even though, the slaves where sending da...
Hi, I recently designed a custom stm32F405RGT6 board. However, I was unable to use the DFU mode.From what I understand, bootloader comes with DFU enabled. However, when I used stm32cubeprogrammer, it kept mentioning "DFU not detected". This is my sch...

Hi Everyone, I am using stm32u575 microcontroller. I am facing issue of stuck the application code in Hardfault handler when jump from internal UART bootloader to the Newly written application code. Lets explain you the full process. I have a applica...
Hello,I have made several tries but non of them could possible solve my problem.In an STM32F030K Series, so Single Bank Flash memory, I am trying to have Flash Operation and UART module works together under the same build.I know that Interrupts durin...
DEar forum I'm designing a system to use a quad spi memory for log purposes. And I see that the L412R8I only features qspi bank 1 on AF10Bank 0 is missingIs it okay? I'd only use it by indirect access, because the memory is to be read and written Are...
Hello everyone,I sent the data by UART with command:uint16_t Size[8];HAL_UART_Transmit_IT(UART_HandleTypeDef *huart, const uint8_t *pData, uint16_t Size)Question: Size on this command is 16 bytes or Size is 8 data elements of array?
Posted on January 30, 2014 at 08:24 There is a bug in CPAL_I2C_IsDeviceReady that prevents it from ever returning failure. /* wait until timeout elapsed or target device acknowledge its address*/ while ((__CPAL_I2C_HAL_GET_ADDR(pDevIn...
Hello,I'm commucating two STM32 F4 boards using SPIThe first board is configured as a Master and used to only transmit data #define message_tx_size 4 uint8_t message_tx[message_tx_size] = "ABCD"; .... int main(void){ while (1){ HAL_SPI_Transmit...
Hi,I work with STM32F412ZG processor. I have also external LSE. I have the next problem related to STOP mode. There are some scenarios we want the processor to go to sleep for x hours. The processor goes to sleep for 5 seconds, doing some job and ret...
