Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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 have a custom board with STM32F746VGT6 MCU, LAN8742A Eth PHY and Ethernet socket. I would like to implement MQTT communication in my project with my board as a client. I am familiar with LwIP and FreeRTOS and use both of these libraries in my...
First and foremost, they aren't perfect. The code has tons of work left. But it took me SO long to get ANY i2s audio data from my guitar to my computer, the major hurdle being mostly the lack of USB Microphone drivers provided by the stack.Now that I...
Hey there,I'm currently working on an audio application for the STM32U5A5 (which I'll later port to the STM32N657), using MDF.The application closely follows the MDF/ADF examples for audio recording found in the U5/N6 Cube firmware packages, with the...
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,I'm trying to get LPBAM Low power timer capture to work in a frequency measurement application. The intention is to use LPBAM to write input captures from LPTIM3 to a buffer in SRAM4 while in Stop mode 2. The app loop just sets a wakeup via the RT...
We develop a measuring device which should be capable of SIL 2. It would be possible to fall back to SIL 1 only. STM32F4 MCU is used with STL-Safety-Library.Has anybody qualified the gcc for that? Or did you replace the compiler by already qualified ...
Looking to add a 4 mic pdm array setup to livetune environment. Had questions on how deep into the environment we need to go for the changes. Is it just a matter of changing the # of channels for the sysIn, # of slots and active slots on the pdm inte...
Hello, I am currently using the NUCLEO-U545RE-Q and trying to set low-power modes with FreeRTOS. I have already seen videos from official ST channel and read documentation but I cannot get to set this functioning when using FreeRTOS and RTC. My goal ...
Hi everyone,I am developing a project on the STM32N657X0H3Q where I need to implement a Dual CDC ACM composite device.I am following the "Standalone" implementation to avoid a full ThreadX dependency, as I plan to integrate this with a FreeRTOS proje...
Hi Community,I am working on STM32H747I-DISCO Board and trying to bringup digital MEMS Mic (MP34DT05) which is integrated on STM32H7-DISCO Board.I am trying to record random voice for 5 seconds and need to play back via audio jack out which is connec...
