Heyho,management asked me about a project involving 1 or 2 audio input channels at 32-bit / 200 kHz and - here's my knowledge almost zero - some "heavy & intense" DSP / FFT algorithms for real-time signal evaluation.We're already using the H723 .. H...
Hello everyone.How do I update the firmware via VCP on STM32F407VET6? Is it possible to do so? If so, what needs to be changed and added? Do I have to recreate the bootloader?I don't know where to start here.Thank you :)
Hi,I'm using an STM32H750XBH6 with an ISSI IS42S32400J-6BL, but the read/write operations keep failing.I’ve tried setting the CLK to 166 MHz / 120 MHz / 100 MHz / 50 MHz, but it still fails.When measuring with an oscilloscope, I found that the FMC_Dx...
Hi everyone . I have timer problem again. I use STM32G431KBT6. I'm using timers. timer 3 for pwm pulse direction servo motor and timer 8 for pwm speed control dc motor. But when start timer8 pwm, timer 3 is starting same time. What could be the reaso...
I have a question about PVD.I have this main.c file. My interrupt function void TM_PVD_Handler(uint8_t status) won't execute when the power goes off. Why? In this case, I'm sending a message to the UART to see if my computer recieves the message befo...

Hi everybody,I've two cards with a STM32F446 on them.My first one works very well, the µc starts a each time.On the second card, the µc starts sometimes (I have a LED on my card that blinks at start).I've checked Vcap (2.2µF), the 3V3 rising (1ms), b...
Hello STM32 community,I’m working on a project where I need to temporarily disable/enable the watchdog before entering into low-power/sleep modes, but I want to avoid resetting the MCU.Here’s the context:I’m using an STM32U385 MCUI know that watchdog...
Hello Team,I want to store encryption Key - 4 byte into Option Byte OR any other memory Except in-built Flash Memory.Is it possible to write in Option Memory ? If not what could be the other option ?
I was configuring USB as virtual com port for stm32f401ccu6 (Black Pill) using HAL. I am getting clock issues. I tried multiple times but can't resolve them. please help me.
