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...
Hi,I have massive trouble while implementing USB HID on a STM32F373.I use the CubeIDE, made a new project configured the USB pins and the USB Device middleware as „Custom Human Interface Device Class„.The report descriptor has a length of 37 Byte and...
Currently I have it working, but while the FLASH READ is about 200us and can be done wholly inside STORAGE_Read_FS (which is within an ISR), the FLASH WRITE takes ~17ms and while it works fine done wholly inside STORAGE_Write_FS, it needs the disabli...
I have been testing Examples_LL code (SPI_TwoBoards_FullDuplex_DMA_Master_Init ) in STM32Cube_FW_G4_V1.4.0 package.Here is my problem:I modified the original code such that I only need one board./* Enable the SPI1 peripheral */ Activate_SPI(); ...
The USB communication fails when connecting F745 MCU to a USB hub that is connected to a PC. Without the hub it is working normally without any errors. Currently the setup consist of a desktop app that sends something to the MCU and expects a respons...
I am using the STM32G071GBU6N to implement 2 USB PD interfaces. Port 1 will be sink, Port 2 will be source. On the sink interface, the dead battery support is needed and DBCC pins will be connected to cc pins. On the source, I do not need dead batte...
In the definition of TIM16_OR_TI1_RMP_Pos in stm32f301x8.h, it's defined as being equal to 6.However, the reference manual (RM0366), Rev 4, p562, suggest that it should be zero.
I want to add a usb connector to my stm32L452, it is powered by an external supply (not usb). I then want to use it as a CDC device, so I can plug into my PC, and it appears as a virtual com port and/or mass storage device. I have some questions:(1) ...
Gooday I have a steering wheel which has buttons programmed with an stm32 blue pill board.... my problem is The board is only recognised on my pcs front USB ports ......any USB ports on the back side of the board give an error (cannot recognise and p...
The system looks like this:-one master controller STM32H7 which holds firmware of slaves-multiple (~8) "slave" STM32H7 on the same FD-CAN busThe slave controller firmware should be upgrades via FD-CAN ST bootloader (see AN5405)AN5405 says "The CAN bo...
