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...
I am using STM32 TCP Echo server client Cube IDE example. I have server and client device. I can connect first time successfully but when I reset the client, I get after 70 line in wireshark screenshot. How Can I solve this problem ? What is the reas...
The documentation for the OPAMP peripheral on the STM32F3 series is completely missing from UM1786. The list goes from (Section 30) "IWDG" to (Section 31) "PCD". Hopefully there aren't more things missing from that range.
Hello, I am using the STM32F2xx ev board to develop a simple application that utilizes the USB port as a HOST. I would like to check if a device has been connected to the port and it causes over-current on the USB.Looking into the source code, It see...
I'm using nucleo f429zi with LWIP v 2.1.2. Documentation states that for TX buffer PBUF_RAM should be used. In my case whole LWIP stack freeze after 28 send messages. When I change pbuf type to PBUF_POOL, everything works like a charm. Although in th...
For some reasons it will be good to write my own MCU serial number for USB purpose.. Is it possible to change seria number of hte MCU and how to do this...
Hi All, I have written simple TCP client using Netconn interface in LWIP on stm32f417 board. Client connects to LWIP server that is also on another stm32f417 board using Netconn api. After first succesfull TCP transmition, connection freezes, when co...
For an application, I need to implement FOTA through UART/USB for STM32L0 microcontroller. Are there any examples or firmware packages available for this?
Both these functions contain the code:"if((HAL_GetTick() - tickstart) >= SDMMC_DATATIMEOUT)"However SDMMC_DATATIMEOUT is defined as 0xFFFFFFFF so the timeout is very long (49 days with a 1ms tick) and therefore never occurs.That upshot is that if the...
Hello, I am using the STM32L4 Micro-chip on a board I am using, and I can across a weird issue with the usb. When ever I was running iar and trying to open up the com port within another serial program, the serial program was unable to open the com p...
I wanted to replace my system that used to work with stm32f407VGT6 with STM32H723VET6 as it is cheaper.I designed a new pcb, followed the steps in the link below and created a project.https://community.st.com/s/article/How-to-create-project-for-STM32...
