Hi, I am developing firmware for an STM32H747 with Ethernet connected via RMII to a LAN8742 PHY. The project uses lwIP and FreeRTOS. UDP communication works fine when sending data, but when receiving UDP packets, the system crashes after some rundom ...
Hi all,I'm currently working on a project using a STM32H753 in combination with the Azure RTOS UsbX to create a composite class USB device (CDC ACM + MSC). As a starting point for the MSC support, I'm using this STM github example:https://github.com/...
Hi, I recently started a project using the STM32H747BIT MCU and I’m configuring ThreadX v6.4.2 as the RTOS. I followed the usual steps to integrate ThreadX into my system. I decided to use the ThreadX source from the GitHub repository instead of the ...
I am using the STM32H523 microcontroller with I3C function and a system clock of 250MHz. I am configuring LL-I3C_SetPeriodClockHighI3C (I3C1,0x0D) based on the LL library;LL_I3C_SetPeriodClockLowPP(I3C1,0x0D);LL_I3C_SetPeriodClockLowOD(I3C1,0x0D);At ...
Hello Microsoft Community,I’m currently working on implementing a file system using FileX and LevelX on external NOR Flash (IS25LP064D) connected to the STM32U585AII6Q board.Flash Memory Specifications:Sector Size: 4 KBBlock Size: 32 KB / 64 KBTotal ...
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 ...
