I am trying to build a sample application that initializes a NOR Flash SPI chip and then exposes it over USB to a Windows computer as a removable mass storage device. I am using FileX and USBX. Host is STM32F429 (Nucleo 144 board) and Nor flash is ...

Hi all,I purchased the nucleo-stm32g474 board and the z-nucleo-USBPDM1. I would like to use the USB port to communicate with the computer at speed (HIGH SPEED). I am unable to find an example of how to do this and how to communicate with the microcon...
Initially I followed the tutorial at https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Getting_started_with_USB-Power_Delivery_Sink#-5BOPTIONAL-5D_Advanced_USB-PD_application but couldn't get that to work. It shows negotiations in the STM UCPD softwa...
Hi all !I want to enter the bootloader in system memory using the Nucleo-F429ZI but without success until now.As I understood, the only thing to do to enter bootloader at reset is driving pin BOOT0 High and BOOT1 Low.What I have tried is :solder the ...
I have successfully connected USBCDC to stdout by redefining __io_putchar and can use printf to talk to a PC thru its virtual serial port but am not having any success with stdin (modifying __io_getchar). Anyone done this and can advise?
I'm implementing, using FreeRTOS, a simple communication protocol based on a 1-wire UART and a request-to-read pin. It has a master and a slave both of them can initiate a read from the other. If both the slave and master want to read at the same tim...
