back-to-back write to the same FSMC address

Hi,In my design, STM32F7 MCU communicates with FPGA via FSMC bus. FPGA emulates an asynchronous NOR flash. It was noticed that when MCU does back-to-back writes (2 lines of assembly code for each write) to the same FSMC address only the last 16-bit w...

STM32F446ZET - CAN TX works in Loopback Mode but not in Normal Mode

Hi,Im struggling to get the CAN to run on the F446ZET micro, it runs all day long transmitting in loopback mode but doesnt work at all in Normal Mode.Looking on a scope trace of the TX pin in loopback you can see the couple of messages im transmittin...

Is it a known bug (stm32h750VBT) that you can't use DAC output2 with Timer5 external trigger(ETR1) ?

just spent a number of hours cursing ... DAC worked as soon as I disable Timer 5

Hi i have to add auo focus camera module to STM32F429 processor for AR smart glass application could any please suggest how to add and is it requires any external driver chipset ? please help

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

stm32f7 FMC interfacing external nonmemory chip, like XR16v798

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...
