In STM32_USB_Device_Library for 'L4, ST kindly changed a key struct definition between versions, changing amongst other things the type of pUserData from plain pointer to an array of pointers.That of course threw a bunch of errors in related user cod...
Hello!I suspect it has been already asked, but nevertheless:stm32f411xe.h: #define USB_OTG_DIEPMSK_TXFURM_Pos (8U) #define USB_OTG_DIEPMSK_TXFURM_Msk (0x1UL << USB_OTG_DIEPMSK_TXFURM_Pos) /*!< 0x00000100 */ #define USB_OTG...
Hello ST Community,I am working on a project using an STM32 microcontroller with USB CDC class for communication. I am using the CDC_Transmit_FS function to send data over USB, but I am looking for best practices to handle the completion of data tran...
Hi allI want to enumerate a Virtual COM Port on my NUCLEO-U5A5ZJ-Q board, using USBX peripheral in standalone mode. I have followed other articles, but they either use RTOS, or a different device class.So my question is:How can I setup the USBX perip...
Hi,I would like to create a gamepad that is recognized by the computer (windows), and have the Virtual Com Port (CDC) to send en receive data with the computer. For that, I want to create an USB Composite with HID+CDC. I found an exemple on this webs...
Dear All,For the needs of my project I need to be able to check if an USB drive is attached to my device, if it is then I need to mount it and then I need to be able to do all the different FatFS commands.So far I have managed to import the FatFS lib...
hi I want to implement mass storage class in STM32H743BG controller. but there is no SDIO pin, we arrangement for SD card and external flash.it is possible to implement it on external flash(IS25lQ128).thanking you
Hi, I'm using an STM32L4R9 on a custom board with USB.The project has the Host Only and Device Only implementations of the CDC Device and a MSC Host stacks.As we don't have a USB-ID pin, we can't really use the normal OTG behaviour, so the project is...
CONTEXT:I have been working with an STM32F429ZI Nucleo, trying to connect a USB thumb drive, to update the user application firmware. I have started with the MSC_Standalone project as it exists as an example for the F429ZI and I have been integrating...
I'm trying to implement a USB touchscreen on a NUCLEO F446ZE. I'm making a full-speed device using ST's USB library (Custom HID class) and I'm testing it with on a Windows 10 host. The first contact registers, but when I try to press another, it doe...
