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...
I am working on an STM32 + Azure RTOS project where I need to access the same SD card in two different modes:When the microcontroller accesses the SD card directly, I use FileX with an SDIO/SPI driver.When the SD card is connected to a PC via USB, I ...
Hi,I'm using STM32H7 dual core, where the data has to be shared between the cores, so im having totally 21 variables totally 76 bytes, thought of do it like a structure, so where to place the structure exactly for this data sharing. so, this structur...
Hi!EDIT: WARNING! This is no real fix... The bug remains...With STM32Cube_FW_F2_V1.9.0 and CDC's /dev/ttyACM0 I had funny glitches on VoidLinux, when i tried full duplex communication (host<>device):some packets never arrived at the USB hostsome shor...
Hi everyone,I tried implementing tickless idle on my STM32H7 CM7 core following a tutorial I found: https://www.youtube.com/watch?v=hVlpf1Rm4QoI suspended the tick (TIM6) and set up LPTIM as the wakeup source.However, I noticed that my core wakes up ...
Hello ST Community,I’m currently testing an SGTL5000 audio codec with the STM32WB55 Nucleo board, and I’ve run into an issue where audio only works when analog test mode is enabled. I’m using the Hathor SGTL5000 audio breakout board from PCBWay (proj...
Hello,I am using the STM32H747IIT6 microcontroller along with the LAN8742A Ethernet PHY, configured in RMII mode. However, I am facing issues where the Ethernet interface is not working at all in my circuit. It appears there may be multiple bugs or c...
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...
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...
