Hello everyone,I'm using AZURERTOS on my STM32F407 microcontroller. My goal is to use the FPU to perform some mathematical operations (FFT, etc.). Could you help me figure out how to activate the FPU and how to tell when it's active, taking into acco...
STM32H523HEYX Flash Write Issue1.I’m currently working on a project using the STM32H523HEYX.I'm using STM32CubeIDE, and the firmware libraries are up to date.I’m also using STM32 X-CUBE-FREERTOS.I’m trying to write data to Flash memory using the foll...
Hi everyone,I’m setting up LVGL on a custom PCB using an STM32H747BIT MCU. The display is connected via LVDS, and I’m using DMA2D for transferring the framebuffer to the screen.The issue I’m facing is that the DMA2D transfer complete callback is neve...
Hello.I've been struggling for several weeks to fix an issue when sending data over MQTT using LwIP on an STM32F407 microcontroller.For periodic message publishing, I'm using the following code:void MqttPublishTask(void const * argument) { err_t err...
Hi All ,Am imported a example project in stm32cube and i tried to build am getting error as Description Resource Path Location Typenon constant or forward reference address expression for section .ARM.extab LTDC_Paint line 90, external location: c:\...
Hello everyone,I ran into a problem. First of all, I have two tablets: one with a bootloader and another without it. Tablet without bootloader works fine so its something bad in bootloader. I’m trying to plug in and unplug the power supply, and somet...
Hi,I'm using an STM32H7 board with a LAN8742 PHY, configured via STM32CubeMX.LwIP is initialized without RTOS, and Ethernet is in RMII mode. The main goal of this project is to receive data over UART and forward it via Ethernet.I want the STM32 board...
Hello , I am working with the STM32H755ZI-Q board and configuring it as a USB Host. I’ve successfully tested the USB Host functionality using standard USB devices such as a keyboard and a mouse, both of which are recognized correctly by the host. How...
Hello,I am trying to fill a buffer from the on-board MEMS microphone using the BSP_AUDIO_IN_RecordPDM() function. However, execution pauses around HAL_SAI_Receive_DMA() and the BSP_AUDIO_IN_IRQHandler() is called. The stack trace is as follows:Checki...
I've been working on a project on STM32F746-Discovery with only CMSIS (no other libraries written by not me) on a Windows machine in STM32CubeIDE. I used the default STM startup file (.s with a vector table and a memory initialization), the startup_s...
