Hello everyone,We use a STM32F7 and we have built a bootloader which uses the USB-DFU library from ST (usbd_dfu_flash). We can successfully program the internal and external flash. We noticed that it takes quite long so we were looking for ways to in...
Specifically for STM32F103C8T6 and STM32F103RCT6.
Hello,Is it possible if MCU communicates with PC in virtual COM port, using USB connected as shown below.USB_DP --- OTG_FS_DPUSB_DM --- OTG_FS_DMCould anybody please show me example?Thank you.
Hi,I'm looking for an example schematic of a USB PD charger interface using STM32G071G8U. Current questions are:Is the available singe CC pad (PA8) all you need from the hardware point of view? Is there any option to connect D+ and D- to allow 5V loa...
Hi,I am working on a custom USB-PD board and trying to make a sink. To check if everything was working as is it supposed to do, I followed the "10-minute" sink example from ST. But when I connect a USB source, the sink keeps detaching the connection ...
Hi,I'm trying to trig a DMA from the EXTI0 input. There is a good example in the STM32Cube package for the H7: Projects\STM32H743I-EVAL\Examples\DMA\DMAMUX_RequestGenBut this example uses the BDMA and I need to use the DMA1. I tried to make some modi...
Hi all:If I plug in USB 2.0 mode high speed port(PC recognition Windows7), frequently enter the ISO in/out incomplete interrupt. but if I plug in USB1.0 mode full speed port,is OK. Once enter the incomplete interrupt.record or playback, audio will b...
I am working on USB CDC ACM device. I want to communicate with High Speed device using full speed host(NUCLEO-F411RE). As I am new to USB protocol, but I know that device starts communication in FS mode and switch to HS mode only if host respond to J...
