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...
Hello everyone.What is the proper procedure when restarting the entire ethernet?Im using LWIP and FreeRTOS and im not sure if im restarting everything correctly...These are the steps im using.Terminate TCP Server thread. netif_set_down(&gnetif); neti...
Hi,I have a STM32F407G-DISC1 board. The final goal is to write a program that get data from the hardware and publish via mqtt, and via the usb (HID client). Also an integrated http server would be great.Is it there online an implementation example fo...
I am using FreeRTOS and lwIP (callback api) on the STM32F407. I have 1 UDP and 2 TCP ports. After a few hours, the struct pbuf_custom *p = LWIP_MEMPOOL_ALLOC(RX_POOL); operation returns NULL. When I checked the ethernetif.c file, I noticed that the E...
Hello.I am using an STM32H743BI processor in the project.I am using freertos.I have completed the connection setup from ethernet. I can ping the device and connect as tcpclient.In the working scenario I need to send data at 100ms intervals as long as...
I'm using the LWIP library and STM32F407. I’m trying to send a 1860 bytes through Ethernet using UDP protocol, exceeding the Ethernet MTU (1500 bytes) so my data is fragmented. I´ve used some programs to test If I could read UDP stream, but nothing ...
Hi, I am using STM32F767ZI for ethernet communication. I update my CUBEIDE version from 1.16.1 to 1.17 latest version. After I update my ethernet program was show HardFault_Handler() during Execution. This was working fine in the previous version(1.1...
Hi,I want to use a single low-level module to handle up to three I2C buses at the same time using the HAL library and using the interrupt for all communications with the relative callback. Is it possible to use a single write/read/callback function f...
Hello,Now I'm testing 50msec regular Stop and wakeup usingHAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 102, RTC_WAKEUPCLOCK_RTCCLK_DIV16);Firstly I expected HAL_RTCEx_WakeUpTimerEventCallback() is done every 50msec but in real it was far faster than expexted.H...
Hi, I'm trying to use https://www.st.com/en/embedded-software/x-cube-eeprom.html on my custom stm32g030 board.Following the examples I write this code: HAL_FLASH_Unlock(); ee_status = EE_Init(EE_FORCED_ERASE); if(ee_status != EE_OK) { Erro...
Hello, while testing the STM32Cube Ux_Device_* examples for STM32C071, I have encountered an issue of them not properly finishing USB enumeration. For example, both Ux_Device_HID and Ux_Device_HID_Standalone stall after the configuration descriptor p...
