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...
Good morning, if possible, I would like more details about the following PDM2PCM(HP version) library used for converting PDM data to PCM. typedef struct{ uint16_t bit_order// MSB / LSB uint16_t endianness;// big endian / little endian uint3...
Hello, I am using an STM32H723ZG6U and want to output a limited number of phase-shifted pulses on two pins. To do so I currently use TIM1 and TIM8 with PWM generation.TIM1 acts as the master timer having channel 1 in 'PWM Generation CH1' as the first...
Hello everyone. How are you?I created a test program based on https://community.st.com/t5/stm32-mcus/how-to-calibrate-the-stm32-s-real-time-clock-rtc/ta-p/744958 I calibrated and compared the signal (512Hz @ PB2) with an oscilloscope, resulting in an...
I’m trying to build a UAC2.0 (USB Audio Class 2.0) device on STM32H7, supporting: High-Speed USB24-bit audioPlayback + RecordingFull-duplex, stable, low-latency operation After reviewing many threads here, I still haven’t found a complete or working ...
helloDescription:I'm currently working with the STM32U585 and encountered an issue related to GPIO behavior after waking up from standby mode.Before entering standby, I configure certain GPIO pull-up:(No external pull-down resistors on the affected p...
Hello everyone, I have a NUCLEO-H723ZG board and I would like to establish Ethernet communication with it. The board already includes a LAN8742 chip as the physical layer. However, in my system there is an external LAN8720 magnetic Ethernet module. A...
Hello everyone, I have the following use case: I want to receive raw data via Ethernet, which works fine, but I have a problem: When I send 100 bytes, I only receive 14 bytes in my software on the MCU (STM32H7S3L8). I was able to fix this by settingA...
Hi, I use STM32H7 with STCUBE 11.1.I use RNDIS module usbd_cdc_rndis.h to communicate with a PC.Sometimes when the PC sends a frame the STM32 replies with NAK, here is the sequence that repeats:SYNCPID OUTAddressCRCEOPSYNCPID DATA0data 30 bytesCRCEO...
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...
i'm trying to receive some data by uart and send by spi, both dma normal mode, i've done comunication separately but when i join them get stuck on spi busy, i tried a lot rtos(queues and semaphores), i changed almost all the code, but i just can't do...
