Posted on February 02, 2015 at 13:03I'm trying to create a USB CDC+MSC composite device using STM32F4 so that it gets automatically recognized by both STM32 CDC driver and as a standard MSC device. Does ST provide a VID/PID pair for such a device? I...
From the document, the sink will check:A SINK must present an Rd resistor and detection is done in two steps:1. detect the presence of Rp resistor2. detect a VBUS ON.I tested in stm32g431rb, connect ucpd_cc to a power adapter(source), Source send the...
I have a custom board with STM32L4R MCU (STM32L4R9ZGJ6). While the application software and its USB interface is running I can't enter the USB bootloader. I checked AN2606 but found no issue. STM32L4R takes its internal clock for USB so it seems easy...
I found my STM32L4R5VG 's bootloader version 9.2. The AN2606 says that the bootloader version 9.2 has a trouble with system reset repeatably so can not be used for bootloader. The version 9.4 resolved this issue. How can I update my STM32L4R5VG 's bo...
Hello. I am working on project where i need to control android tablet from MCU (making car headunit with STM32F411E)I have working ReportDesc that suits my needs, no matter how hard i try i can't make it work on my program in HID library, All i have ...
Help please. I have a STM32F0 and two STM32H750 micros all sharing Tx,Rx and Boot 0 lines but separate reset lines to a host processor running Linux. I need to be able to reprogram all three STM32's one at a time from the host. The F0 works fine, no...
I am using the CDC library as a quick way to get USB communication with a linux machine. I understand that to use the USBD_CDC_TransmitPacket() function you first check the TxState variable in the CDC handle struct then set the buffer with USBD_CDC_...
This link only displays a blank page. Other H7 MCU's are displayed.https://www.st.com/en/microcontrollers-microprocessors/stm32h743-753.htmlNot a question, I know. More of a technical issue with the website. I tried two different browsers.
I use stm32cubemx try to create a usb pd project, but usb pd can't be choosed.stm32g431rbtx.
