Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hi, i'm trying to make a firmware that can read an SD card with filex but that can also connect that SD card to USBX MSC device (no simultaney). i'm able to do the two functionality in two separate firmware, but the problem is to merge. for now is su...
Hi everyone!I'm trying to figure out what's wrong with my SPI Peripheral continous transmitting/receiving via DMA in Circular Mode. I think I have coded a pretty basic "Hello, World" for working with DMA, I've just generated code from .ioc file and t...
DMA stops working when I enable IWDG in .ioc on my STM32, even when commenting out the IWDG initialization for testing. DMA stops working when I enable IWDG in .ioc on my STM32, even when commenting out the IWDG initialization for testing. Before ena...
Hello,I'm working on a low power project using STM32U073 with FreeRTOS, LPUART2 and LPTIM1.To achieve the lowest system power possible I am trying to use STOP2 for when the system is idle.Currently I have LPTIM1 releasing a semaphore every 1 second w...
Hello Forum,I'm trying to get a simple application, running on a NUCLEO-U5A5ZJ-Q dev board, to jump to the system bootloader from FreeRTOS. I've also got AN2606 to hand (application note for the STM bootloader) and RM0456 (STM32 U5 reference manual)....
Hello I have custom board with STM32N657. I have set timer 2 to output PWM pulse on channel3 and output compare pulse on channel 1 as trigger to another timer. The timer starts when external trigger - TIMER4_ETR (mapped to timer 2) detects rising edg...
Please refer to this thread that, for some reason, @FBL accepted as an answer (it is not) https://community.st.com/t5/stm32-mcus-embedded-software/usbx-audio-class-frame-done-callback-not-called/td-p/855262I'm seeing that when I try to start an audio...
I've set up my STM32U5A9J-DK to use ThreadX and connect to my PC via USBX and Audio Class.I'm correctly see the Audio Device on my PC and I can easily stream audio to it. The only thing is that, for some reason, the callback for new frame done is not...
Hello, i created a custom external loader for a STM32F429 board.The problem is now, my code needs HAL_Delay() for generating short delays between flash device accesses. And the code freezes when executing HAL_Delay(). So i have read that interrupts a...
I'm using STM32G474 with dual ADC injected simultaneous mode. İndividual ADC injected mode works ok. ADC1 is triggered by TIM1 Channel 4 and the interrupt is firing correctly, but ADC2 always returns zero. Questions: Why does ADC2->JDR1 always retu...
