Hi, I am new to MQTT and LWIP.I am trying to implement MQTT client in STM32F407 and to connect to MQTT server through LWIP.When I tried connecting to MQTT server, I received authentication error in server side.Kindly help resolve the issue. mqtt_clie...
I am working on a new PCB/platform based on the STM32H730 MCU.In general, all peripheral drivers work well, using Cube MX.But I have a problem with the ADC sampling:I quite often see errors on the ADC sampling, when USB is connected to PC.But only wh...
Dear ST Microelectronics Team! I am coding commnuication between STM32H750 and SdMicro use SDMMC - FATS from cubemx. But I have a proplem about commnunication about STM32H750 and Sd Micro using SDMMC FATS.Step 1: I open a file by using funtion: 1. re...
I'm making a keyboard using STM32F103VET6.Sleep mode was successful using keyboards.But, It does not wake up.A problem was found in the code below. (pdev->dev_state == USBD_STATE_SUSPENDED)uint8_t USBD_HID_SendReport(USBD_HandleTypeDef *pdev, uin...
hi its been months since i started my journey with the ethernet port i need to communicate via UDP to a pc to get data from the board and send i succeeded some times where some of my projects worked for a while then stopped sometimes the board doesnt...
Hello,I had a lot of troubles with Ethernet connection on this STM32F746ZG Nucleo-board.So I decided to make it as simple as possible to make it working.First step was to ping my board.At this step, I discovered after too much time that we cannot pin...
Hi,I would like to use the X-CUBE-STL on a STM32F446RE to trigger a STO (safe torque off) and a SLS (safe limited speed) with PLc. The STO is no problem at all, since the controller can trigger that directly by using two input GPIOs and one output GP...
We are developing a single pair ethernet board using STM32H725VG as MCU and DP83TD510E (Texas Instruments) as PHY. MCU and PHY are interfaced through RMII mode (10Mbps).When we run our application, the problem is that MCU drops some ethernet packets ...
I have a GPS module and I use it by connecting it to my computer via USB.I also want a CAN bus output. Can I use the STM32F730R8T6 processor?How can I introduce the information from the USB to the STM32 processor? Which pins should I use?After doing ...
Hi,I'm trying to run the Getting Started firmware for the B-L475E-IOT01A board but I'm having problems to connect to WiFi. The error messages are:"ERROR: C:\STM32CubeExpansion_Cloud_AWS_V1.4.1\Middlewares\ST\STM32_Connect_Library\core\net_core.c:327 ...
