I have HID keyboard running on HS and trying to add a touch screen on FSbut when it enumerates the touch screen has a pif->bInterfaceSubClass = 0 , causing a fail in USBH_FindInterface pif->bInterfaceSubClass is automatically populated by the Touch ...
hello, i starting a project in STM32F103C8T6 bluepill.it's my first project on STM32.configure my hight resonator, usb + cdc + debug, like all the video on youtube.but for my not works.my hardware is correct R10=1.5KO, enumeration was good. COM29.but...
I'd like to implement a USB host on my STM32F7x3 so that I can connect a USB mouse to it. I'm somewhat confused about VBUS, though.This is the respective diagram in the AN4879 USB Hardware Guide:According to the description, the box "Current limiter ...
Hello.I have found a bug in USB implementation in STM32CubeH7 (1.4.0 - 1.6.0). Steps to reproduce:1) Open the project from STM32H743I-EVAL\Applications\USB_Device\MSC_Standalone\MDK-ARM directory2) Apply HEAP fix from https://github.com/STMicroelectr...
I use stm32F746 & FreeRTOS & SDMMC & DMA.When I use f_open in somewhere it will return FR_NOT_ENABLED...But in my system have the other f_open & f_write is normal work(I am not remount).My English is not very good,if anything can't understand pl...
Hello,I am using fatfs library developed by http://elm-chan.org/ for reading/writing file system in usb mass storage using stm32f4.As I know, for improving speed throughput one should write data buffer in a multiple of sector size (512B). As stated i...
Hello:Problems with the USART1 receive call on this device. Or is it me? I hope not.I have a serial decode option on my scope. I can see what I send out, and what comes back, every byte. This is my call to receive:rxChar[50];HAL_UART_Receive_IT(&huar...
Hi, All!I am writing a driver to support a custom usb device (like CDC Class). I use example stm324xG-EVAL_USBH-HS (yes, HS). I have a recording made using a wireshark (linux - device):1) make the first request2) get a confirmation 3) asking for an a...
Hello,I'm working with the CAN Module from the STM32F446RE board which has the MCU mentioned in the title. I'm trying to transmit some data on the UART via Tera Term terminal and take this data and send it via Loopback mode and read it back. For star...
I am try to do the project with this controller as a usb mass storage device for a small application. what steps i will do for that, but i already tried the tutorial given by the st.com. but its discussed for f4 series but need f103 series. please he...
