STM32 MCUs Embedded software

loading fw to stm32l412 using st-link (MB1440B) through I2C (internal bootloader) not working.

I am trying to load fw to stm32l412 using st-link (MB1440B) through I2C, but it keeps giving me " Error: ST-LINK error (BRG_I2C_ERR)" .I am sure that the MCU bootloader is active because the MCU sends back ACK.(i used another MCU to check i2c).Accord...

It's too difficult to analyze the example udptcp_echo_server_netconnd with stm32f4Discovery. I want to receive the received data buffer and return the desired data. Can I know how to modify the code?

I am using a STM32H743 to access a SD card using the ST micro driver code. I m NOT using interrupts for the MMC however if an interrupt occurs during a file access the code sometimes crashes. By crashes I mean the read routine times out.

Why isn't the SDMMC code tolerant to interrupts?

STM32L462 With USB DFU goes into Hardware fault when in the methods from usb_dfu_if.c I use the HAL_FLASHEx_Erase.

I have made a DFU application on the STM32L462RET6 CPU.From the CUBEIDE I set the:HSEEnable USBSelect the DFU as a Class For fs Ip.Set the app start address to 0x8008000 Set the DFU media interface to @Internal Flash  /0x08000000/01*032Ka,01*480KgSet...

Stm32L4R5 GPIO Interrupt Enable causes issue.(FreeRTOS)

Hello Everyone,Hope all are doing well.I am currently working with a board based on STM32L4R5 in FreeRTOS environment.I have two UARTS and some GPIO connected.I have one task monitoring the UART data. Both UART have an associated ISRThese ISR place t...

HAL_RTCEx_GetTimeStamp

why  sTimeStampDate->Year = 0U; variable is cleared when time stamp is read?

What should I get from HAL_DFSDM_FilterGetRegularValue function?

Hello everyone, Can someone clarify what I'm reading in this function? This will be the value of the analog signal or it is a 1 and 0 train that I should pass through a digital lowpass filter?RegardsAlan
