Today I decided to improve the performance of my USB driver by transferring multiple IN packets at a time, instead of one at a time. This in theory would be relatively easy, as I can just configure the IN endpoint's TX-FIFO to have a larger allocatio...
Hi, i'm using my Nucleo STM32F401RE as a HID Device for a MIDI Keyboard projectI have configured the following:Connectivity --> USB_OTG_FS --> Device OnlyMiddleware --> USB_DEVICE --> Human Interface DeviceI followed a video tutorial to configure the...
Hello team, Is there any way to format the external flash of microcontroller, the reason is that that flash is acting as USB MSC Device. As soon as it connects to PC a popup will arise for disk format. Am planning to do complete mass...
Hi,during porting the USBX as host stack to an stm32h7 I was getting an error indication,that a semaphore was used during interrupt context (OTG_HS_IRQHandler).For my opinion, it is wrong to call the generated code out of the ISR without decoupling t...
I've been previously programming the STM32F103C6T6 blue pill with an FTDI via UART and am now trying to flash a USB bootloader binary to program it directly via USB.I've closely followed the guide on https://www.electrosoftcloud.com/en/stm32f103-boot...
I'm writing my own USB BOT device driver, and I'm receiving the SCSI opcode 0xA1, which isn't defined in SPC or SBC, but rather in the ATA Command Pass-Through specification. Even WireShark doesn't recognize it.What exactly is the significance of thi...
I am trying to make a USB HID self powered device with STM32G473 without VBUS. I understand that I will require VBUS sensing on reconnection but even when I have already connected the USB then power up my device I only get reset request from host aft...
This is a long one, so sit tight around the campfire, and let me tell you the tale of The Futility of EPENA.Several days ago, I began to implement a Mass Storage interface for my own USB stack, equipped with a Bulk IN and OUT endpoint. The first thin...
I have STM32F407G-DISC board.Hello Everyone,Problem: I am working with a instrument where we frequently get the problem of frequency drop out, i.e. suddenly frequency signal goes missing i.e. goes to zero, this cause the loss in data as shown in the ...
Sure, here is the translation of your query in a polite tone:I am using an STM32L072CB to validate an HID device and I want to switch between Input Reports based on the PC settings, using different Endpoints. However, after sending the Input Report ...
