Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Is there an STMF4xx example project I can reference for using a virtual COM port to connect to FreeRTOS+CLI? I tried to do this myself by having the FreeRTOS+CLI function _write() call CDC_Transmit_FS() and by having CDC_Receive_FS() call a function ...
Hi ST Community,once again I have found a USB PD Specification violation, that I can't find the reason for:Source operation: According to USB PD Spec the order of action is as follows:1. Detect Sink using CC lines and only if sink is detected continu...
Hello @Community, I am working on the STM32F746NG board. In my application, I want to communicate with a PLC using the EtherNet/IP communication protocol to exchange real-time data. The problem I am facing is that my board does not respond to ping wh...
Hello,I need to communicate with a component whose configuration register expects a 9-bit value. However, my current SPI setup sends data in 8-bit chunks.In this case, what would be the correct approach? Should I send two bytes back-to-back? Or would...
Hi，I would like to in-live upgrade firmware of STM32F407 through USART1, that means in-application program(IAP) . If I remember right, there need a trigger signal from key meanwhile NRST is low.My question is that the Key signal could be connected t...
Hi EveryoneGreetingsWe are using an STM32U585 MCU and need to maintain a log of about 200 KB using FileX. Once the 200 KB storage is full, I don’t want LevelX to reclaim the entire file and erase it. Instead, I need the log to behave like a circular ...
I was looking for a way to create a high level abstracted layer that can be agnostic to the lower layer TCP/IP stack, like NetxDuo or LWIP, running under the higher abstracted layer.I have came across suggestion to implement a `plug-in` based impleme...
Hi everyone!I'm having trouble in measuring the VBAT through ADC. I'm using 3.3V on aNUCLEO_476 board to connect to VBAT and when I measure VBAT through ADC,I cannot obtain the value of the VBATHere's my code:void MX_ADC1_Init(void) { /* USER CODE...
Hi I am evaluating STM32F303RE for a product and will be using https://www.st.com/en/evaluation-tools/nucleo-f303re.html for evaluation My technical requirements are FreeRTOS support is mandatory, as our applications use a communication stack support...
Hello,I can run older TCP/IP examples on my F767 Nucleo but I want to start fresh and understand what is going on.Basic project started with CubeIDE/CubeMX code generation. FreeRTOS, LWIP, fixed IP => Does not answer to ping. Turns out MX_LWIP_Init()...
