Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
While writing the simplest example I could come up for using the HAL I2C routines, I came across what seems like a clear-cut bug. This is for the latest version of STM32CubeF4 (1.24.0), identified in stm32f4xx_hal.c as "STM32F4xx HAL Driver version n...
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.
