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 everybody. I'm trying to make LWIP work on NUCLEO-H723ZG board, but I can't even get a ping response so far, even with static (DHCP disabled) network configuration. The project uses FreeRTOS (CMSIS API v2) and is created with MX tool. It seems ...
I am trying to create a simple UDP server using the NUCLEO-H743ZI2 board. I will port this to a similar microcontroller in the same family (STM32H750B) once I get it working. I am able to build the example code from this repository: https://github.co...
When using a USB CDC device, especially at high data rates, there is a possibility for packet loss. This post illustrates the issue with what I consider convincing evidence. This isn't a STM32 bug, but it's something you may encounter when interfacin...
Hello,I am using an STM32H743 microcontroller. UART8 is configured at a baud rate of 460800 with DMA enabled. The UART output is logged by a USB logger which creates a FAT32 text file.The transmitted data contains mixed data types such as integers, c...
Good evening, now that I can ping my F767ZI board with my laptop, I'm trying to use some tutorials on the web to be able to send data (numbers or message strings) to a server (Hercules software set as a TCP server), but I'm having some difficulties (...
Hi everyone,I am working on a project with the NUCLEO-H7S3L8 and trying to read 2 ADCs simultaneously in Continuous Conversion mode using HPDMA.The Goal:ADC1 & ADC2: Reading 7 channels each (14 channels total).Mode: Continuous Conversion, Circular Mo...
下面是我的部分函数，普通串口按照这个配置，是可以正常进入回调函数，但是LPuart却不能进入回调函数，不知道问题出在哪里，使用stm32cubemx6.16.0,附件是ioc文件， Post Edited by ST moderator to apply source code formatting and translate from Chinese to English to comply with the community rule: Below are some of my ...
I have updated the STM32L4 HAL drivers to V1.13.6 / 14-November-2025 (1.18.2), which has broken my implementation of HAL_UARTEx_ReceiveToIdle_DMA.Is this a fault in the new HAL drivers or does user code need to be updated inside the HAL_UARTEx_RxEven...
I have one question regarding the HAL_FLASH_Program function. I use the HAL_FLASH_Program many times during the runtime of the firmware. I use it to store log, warnings and errors in the several flash pages. When the page is full and I must write int...
When I call function HAL_FLASH_Program twice with the same Flash address, the second call is ignored. See test code below.int8_t buffer1[16] = {0x00,0x01,0x02,0x03,0x04,0x05,0x06,0x07,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF};int8_t buffer2[16] = {0xF...
