Platform: STM32 Nucleo-H7A3ZI-QGoal: Read audio from four microphones in stereo mode (two mics per I²S interface) via DMA, then enqueue complete stereo frames for processing.1. Hardware & DMA SetupI2S1 handles Mic 1 (left) and Mic 2 (right).I2S2 han...
I'm able to generate a simple PWM signal but I wasn't able to generate arbitrary waveform with DMA (HAL_TIM_DMABurst_MultiWriteStart).How should be configured the DMA ?Is there an example that use PWM with DMA on STM32U5 ?
Question:I’m using an STM32H7A3ZI-Q with four INMP441 MEMS microphones. Each INMP441 outputs PCM (not PDM), and all four share the same BCLK (bit clock) and LRCLK/WS (word select). I’ve split the data lines into two stereo pairs:SAI_A (master) → Micr...
Hello community,I have been working towards getting a prototype ThreadX modules project on my board (Nucleo U545RE-Q) using CMake from a generated STM32CubeMX project. I have been loosely following the documentation https://github.com/eclipse-threadx...
Hi everyone,I am trying to send the firmware to the MCU via webpage. I want to send chunks of the file (4096 bytes) to the mcu, so it can store in ram, do some checks and then store it in an external memory. The firmware size can be maximum of 1.7MB ...
Board: NUCLEO-144 STM32H723ZGI'm using ADC_3 with 8-bit resolution, trying to measure an analog sine wave of 1 kHz as a stimulus.I'm trying to use the ADC with DMA. However, I am unable to get any values other than zero. I have tested it in polling m...
Hello ST Community,I recently purchased the STM32N6570-DK development board. However, I accidentally erased the default factory firmware by programming it with my own application, without saving the original files.As a result, I am no longer able to ...
Hello,I am looking for the MCU for my project. I need the Ethernet and Can bus, so STM32F429 was in my mind first, but as I don't need the display function, I tried to find more affordable option.But I couldn't find the right one in STM32F4 series, a...
Hi to everybody.I can't get spi to work with linked lists. I followed the procedures in the documentation but it still doesn't work. Maybe someone can tell me why.This is my configuration: STM32U575, cubeMX 6.12.0, cubeIDE 1.9.0The linked list has tw...
Hey everyone,I’m working on a USB audio project using TinyUSB on my STM32H7S78-DK Discovery board, and I’ve hit a wall with UAC2.0 on the High-Speed port. I’m hoping someone here has experience with this setup and can point me in the right direction!...
