Hello.I have a custom board with STM32F750 MCU which has 64KB Internal Flash. Since the MCU's internal Flash is very limited i added external flash to board. I developed 2 different projects for Internal and External Flash. Internal Project starts wi...
Hi,I am using STM32H743 nucleo board. I am looking to configure the USB interface as Audio Class 2.0 device. Is there any middleware available to achieve this?Does STM has any plan to support Audio Class 2.0 middleware? Current middleware only suppor...
Hello,I am using freertos configured by STM32CubeMx.The IWDG is activated and configured by STM32CubeMx too.I met an issue in my code but this is not the purpose of this post.Due to this issue the STM32L431 stays blocked indefinitly despite the IWDG ...
Hi. Im using HRTIM and HAL in my project.To stop Master timer with subsequent interrupt call I use HAL_HRTIM_WaveformCounterStop_IT (it is defined in stm32_hal_legacy.h) and it calls HAL_HRTIM_WaveformCountStop_IT from stm32g4xx_hal_hrtim.c.Pic.1 sho...
Hello, I am working on Ethernet with the STM32H753 board. After configuring the necessary Ethernet settings, I can ping the assigned IP address of the board. However, after a few minutes, I can no longer ping it. What could be the reason for this iss...
Hello, I can't get a USB connection with my stm32 cards, I tried several cards: Bluepill, Blackpill,STM32F429ZI-DISCO, NUCLEO-F767ZI. I still have the same problem "USN NOT RECOGNIZED",do I need to install a driver ?how can I solve the problem ?Best ...
Hi ST Community,I’m working on a project where I need to implement an MQTT client on an STM32 microcontroller. Here’s my current setup:I have an MQTT broker running on my PC using Mosquitto.I’ve written a simple C program for publishing messages, and...
I'm using an STM32G071G8U6TR and a CP2102N-Axx-xQFN28 to communicate over USB. I am managing to get messages onto the STM32 but it seems that the first few characters of the message are coming through jumbled, #include "main.h" #include "UART_Poll...
I have an application with STM32F4 OTG configured as USB Host, MSC, using ST's USB Host middleware and FatFS. How should it respond to rising and falling edges on the OverCurrent signal, such as pictured below (from the STM32F429I-DISC1 schematic)? ...
Hello,I'm using AzRTOS with FileX. Currently, I can detect when the SD card is plugged in, then I initialize the hardware, and call fx_media_open(). The filesystem works as expected.I can also unmount the media with fx_media_close(), and the user ...
