Getting the wrong status value from HAL Libabry

Hello,I configure the DAC using SPI configuration. I am reading the DAC registers value , when register is read back i got wrong status value from HAL Library why these happened?for(i=0,j=0,k=0;i<=46;i++,j++,k++) { Read( SAW_ADD[i],SAW_Val[j],SAW_...

EEPROM emulation in FLASH with Nucleo STM32L432KC & Linker File

Hello all,I'd like to use a portion of my FLASH memory to save four 16-bit preset values. I've read that some STM have several Flash Type Program such as byte, halfword, etc. Unfortunately, it seems that the L432KC only authorizes double word type.Th...

After reading the stm32F401 reference document, it appears jtag boundary scan is not supported unless using full 5 wire JTAG interface and SWD will prevent access to this feature. Can I get confirmation on this?

Hi everybody. I use a STM32H7A3ZI. In my schematic I forgot some capacitors and I can't flash it using a ST LINK V2. Could anyone tell me a basic schematic with essential components and nets to work with it? Thanks.

On STM32U585 the GPIO G are not driveable (while others are fine)

Hello, While trying to setup an UART connection with a STM32U585ZIT6, we realized that it was not possible to drive the G connectors. To isolate the issue we tried to drive others GPIOs and they are totally fine while GPIOs G remain stuck at GND. We ...
