Maximum current for Nucleo board's regulator when powered with 12V supply

Hi all,I want to use Nucleo-F302R8 or Nucleo-F303K8 and want to power it from a 12V supply. Nucleo board also supplies current to a sensor ect. so the board regulator sinks up to 100mA. In that case I measured the current sinked by the board's regula...

How do I turn on or put a logic 1 to GPIOC_ODR PC0 or pin 0 on the STEM32 microprocessor using Assembly language? To elaborate my question, what is the constant in decimal or hex to put logic 1 into the memory address of GPIOC_ODR on Pin 0

Hi.I`m going to use an octal uart IC named XR16V798 and my MCU is a stm32f756z,I printed my own designed board which connected these two ICs as follows:just to mention, I haven`t used FMC with any other device before, now I dont know how to work with...

Help with HAL_FLASHEx_DATAEEPROM_Program() function on STM32L0

Hello all,I have a problem with the HAL_FLASHEx_DATAEEPROM_Program() function and maybe someone can help me. I am using an stm32L073. The address range oft he EEprom ist from 0x0808 0000 to 0x0808 17FF. I tried a simple test for writing to the EEprom...

Software reset issue

1. HAL_NVIC_SystemReset() does not work. it always stays at __NOP(), no reset  for(;;)                              /* wait until reset */ {  __NOP(); }2. Before I implemented ADC with DMA, the soft reset below works. But after implemented ADC with D...

DMA memory to memory doesn't work

Hi guys im doing a simple 5 byte memory to memory dma transfer with timer update request.As stm32f407 reference manual said timer8 update is connected to dma2 stream 1.Here is the timer config by cube.And the dma cube config:I started the dma and exp...

STM32L432 and STM32H745 DAC in DMA mode has shifted data output

Hi, I have a problem with DAC output, same problem with STM32L4 and STM32H7. I have to continuously output a step wave (3 levels), for this purpose I use a Timer and DMA in circular mode to output an array of 3 values.The code is very simple, I use a...
