STM32 MCUs Embedded software

SM32F011F3 - ADC DMA, HAL_ADC_ConvCpltCallback only called once. Variable set 1 but not grabbed by if. Code only running after programming.

Hello ST-Community!I am having a very rough start with my first project using an STM32 MCU. My task is actually very simple and I was confident I could fit this in 8kb of program memory. It actually fits the flash in release build, but I cannot debug...

I could not re-flash STM32L432KC, now my IDE is not recognizing it. I feel there could be issues with the bootloader. My question is can I program bootloader? Is the bootloader part of hardware or can it be updated?

Is it possible to configure the Systick timer, used as timebase generator for theCUBEHAL and the rtOS, so that it generate an exception with a period less than 1msec (forn instance, .5 msec or .1 msec). Thanks for your answer, Piero

Send value in UDP packet

Hello,I have a problem. My program doesn't send value in UDP packet and program crash. I try everything, But I didn't find anything.Some variables and constantstypedef struct UDPsender { struct netconn *udp_sender_server; struct netbuf *udp_send_bu...

Ethernet connection not detecting on stm32h743vit6.

I worked on ethernet in NUCLEO-H743ZI2 and it was working properly. But when I developed my own PCB and used the same ethernet circuit as nucleo board, ethernet connection is not even detected.

STM32F4 I2C HAL Driver problem

Hi STM,I am using STM32F4 I2C with DMA as a slave device.I found that the below snippet of code in I2C_ITError function (stm32f4xx_hal_i2c.c, line 6146) assumed that if hdmatx is not in HAL_DMA_STATE_READY, then it must be hdmarx in HAL_DMA_STATE_REA...

STM32F446 + DMA + FATFS + SDIO

Hello everybody,using Fatfs and f_write, when writing the file "1, 2, 3, 4" to the SDCard, I can see that what is written on the SDCard is "0,0,0,0,1,2,3,4" . What layer is inserting the 4 "0" at the beginning of the file and why ? Is it an 32bits a...

STM32L452 current consumption in STOP 2 mode is less than datasheet indications.

When I run the PWR_STOP2 example from the STM32Cube_FW_L4_V1.15.0 on a STM32L452VE, I measure a current consumption egal to 1.6 uA instead of 2.05 uA.The datasheet and STM32CubeMX indicate 2.05 uA without RTC for this target.It's a great news 8) but...

How do I set the user_configuration especially nBOOT_SEL, nBOOT1, nBOOT0 with the I2C protocol used in the STM32 bootloader?

I tried to set the option byte via write memory command using the address: 0x1FFF7800, but it don't work it always returns a NACK. If I try to read from this address no problem occurs.I also tried to read FLASH_CR (0x4002 2014) and to write FLASH_KEY...
