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,I am trying to get Ethernet-over-USB working on a STM32U585. I want to be able to use both RNDIS and CDC-ECM, but I decided to start with RNDIS first. After a lot of trial and error and research, I am running out of ideas as to why my PC does n...
我使用的芯片是G071RB，当我使用STM32UCPD发status，直接从FF01(PD协议的DP模式)变成0x00000，并且在抓包发现再发送的时候没有发VDO000000001，返回的数据中HPD为0，有没有大佬知道怎么解决 Translation: I'm using the STM32G071RB MCU. When I send a status update using STM32UCPD, it jumps directly from FF01 (DP mode of the P...
I have changed the ThreadX system timebase on an STM32H7 from 10 ms to 1 ms (i.e., the RTOS tick is now 1 ms). The application is quite large and makes extensive use of ThreadX services such as thread delays, semaphores, mutexes, event flags, and tim...
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...
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 ...
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...
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 (...
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...
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...
I am working with the NUCLEO-N657X0-Q and I am looking for a reference project or a pointer to an example that implements USB Host Mass Storage Class (MSC).My Goal: I need to mount a USB memory stick to read test vectors, process them using the Corte...
