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 ...
Hello,I'm using AzRTOS with threadX and FileX. I have a thread with msg_queue that monitors the SD_Detect pin. The code works properly, I detect the card insertion/removal process. The problem is I need to re-initialize the SDMCC hardware so it ca...
Hi, We are developing PD multiport design with TCPM/TCPC architecture, but we've come across a post of CPM stack should be no longer supported for newer products. https://community.st.com/t5/stm32-mcus-embedded-software/usbc-pd-tcpm-on-the-stm32u5/m-...
