Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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...
App note AN2606 on bootloader operation, figure 57, shows the flow chart for the STM32H74/75 series. One block is labeled "USB cable Detected". Exactly what is the criteria for this? Is it based on DP/DM states? Is it based on VBUS measurement? ...
usually I learn by digging and figuring things out, but im noticing that my world of lua isn't going to help me here. I have no real Knowledge of Low Level Languages, is there a tutorial or something out there that can help me learn how to do GPIO t...
Could you tell me which parameters need to be activated for enable SSI? I want to split a page to some blocks.<!--#include file="menu.html"-->
https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-workingI created a working project by following these steps.single protocol sometimes works by losing packets. (I need help with packet loss too.)I want...
Hello,I have an issue with USB CDC in my project. it worked flowless till I tried to send faster. Fisrt I was using :CDC_Transmit_HS((uint8_t *)pSendBuffer , length); without pb at all.But if I send with a higer data rate the TxState are continiously...
Hi I cannot understand why my opt.h file cannot see the lwipopts.h file in the same folder.Presumably, it must be something to do with the 'Wno-stringop-overflow' warning.This contains a very long string - -mcpu=cortex-m7 -std=gnu11 -g3 -DUSE_HAL_DRI...
Hello,I would like to reproduce this example of updating the firmware via USB disk. But I'm not getting the message "Press and release user button to start FW update" to appear. I think I'm missing something about the application's memory vector.Trai...
We are planning to use STM32G071 in our next project.We would like to have 9V@3A in PDO1.So we edited the PDO1 data in the usbpd_pdo_defs.h file as follows.[0x0202D12C]00 0 0 0 0 1 00 000 0010110100 0100101100Bit Description ...
I recently had to look at the SVD file for STM32F2 series chips, and found that the STM32F215.svd file contains entries for Ethernet and DCMI peripherals, even though that's the discriminating feature between them and the STM32F2x7 chips that they do...
Hello,I wonder, is it possible to receive more than one char (1 byte) at the time? For now I can only receive one in one message, i can't find the solution to receive more. Here is my code:/**usbd_cdc_if.c**/ static int8_t CDC_Receive_FS(uint8_t* Buf...
