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...
Hello,I'm trying to detect a USB stick insertion event to write a text file in the stick. I'm working on a NUCLEO-H563ZI with a jumper connected to JP2 USB USER line and a USB TYPE-C TYPE-A connector attacched in CN13. I started the code from an ST ...
I am using STM32N657 with USBX (MSC device).The function ux_device_stack_initialize() is returning UX_ERROR, and after debugging inside USBX I found that the failure occurs when USBX tries to allocate endpoint transfer buffers. The failing code insid...
I want to stop generating a PWM signal after 22 clock edges. It seems like the TIMx_RCR register (repetition counter register) should work for this. My code started from the CubeMX generated code but I have had to remove a lot of it for performance ...
HiInitial situationMCU = STM32U599VJTxQSTM32CubeIDE = v1.19.0TouchGFX = v4.26.0EEPROM Emulator = x-cube-eeprom-v8-0-0 (downloaded direct from STM website)I use the eeprom emulator to save an array of 251 bytes permant on the flash. To save the data i...
I have set up a STM32U5 nucleo board with an additional 8M of memory using an APS6404, following the example in AN5050. Initial setup was straightforward, but trying to create a ThreadX thread that uses an array in that section of memory as its stack...
Hi everyone,I’m working with the STM32WB05KZ using the BLE RC Peripheral example from STM32CubeMX.I added a push button on PA1 and an LED on PA0.My goal:Read PA1 button stateTurn ON LED on PA0 when button is pressedSend BLE notification to the centr...
HI all i have been working with LTDC to drive an external RGB parallel display . i made it working by placing the framebuffer inside internal RAM . i got output with good update speed. but when i try to incoperate FREERTOS with this project the outp...
Hi everyone,I'm working on an audio acquisition project using the STM32H743ZIT6 microcontroller. The goal is to build a microphone array with 8 digital MEMS microphones (MP34DT05-A), connected via DFSDM and streamed over USB to a PC using the USB Aud...
Hi everyone,I’m working on an audio project with an STM32H743ZIT6 and a MEMS microphone (MP34DT05-A). Audio is captured via DFSDM + DMA, and the DMA callback (HAL_DFSDM_FilterRegConvCpltCallback) fires reliably with fresh PCM audio samples.At the mo...
Hi, I’m trying to get SDMMC + FileX + ThreadX working on an STM32H5 (NUCLEO-H563ZI) and I can’t find any complete example. SDMMC works on its own, but once I enable FileX, fx_media_open fails and no files get created. I’ve tried the H573 FileX exampl...
