I’m trying to establish USART communication between two STM32F407-Discovery boards, where one board acts as Master and the other as Slave.Hardware setupMaster Board clk -> save board Clk - [common clock]Master Board TX → Slave Board RXMaster Board R...
Hello,I have this board that I have to use for the project. I am using STM32H7S3H8 and 4x MEMS microphone, and I am strugling to get to the point where only math with CMSIS-DSP is important. Is there any example, .ioc file that I could look up to for...
Hello everybody.This is my first post in this forum and I am quite new to the stm32 MCUs. So sorry in advance if I dont know or misunderstand some things. Right now I am working on a setup to read values from a sensor (dps310) and print them in a con...
I was used normal mode USB CDC with Host Only -> and in middleware ( USB CDC) And it worked no matter what and good for beginners. After Update That files ware missed with same settings-up for new project. i was in middle in middle of the project for...
I am trying to implement Mass storage class in STM32U083RCT6. i thought to implement mass storage on external flash but it is not happening for RAM memory itself USB is not working.
STM32H5 USB Custom HID CubeMX issue.When setting parameter "UX_DEVICE_CLASS_HID_EVENT_BUFFER_LENGTH" to 64 in CubeMX, the corresponding define in the "ux_user.h" file is commented out.Setting this parameter to any other valid value (between 0 and 255...

I have tried USB examples for Stm32F070, F401, F407 Black board and calling a single "CDC_Transmit_FS" function to print a string but none is working. The hcdc->TxState value is some garbage big value so it always stay busy and also not getting inter...
I am using STM32U5G9 implementing USB MSC device. When calling function ux_device_stack_initialize(), it returns error 18, which is correspond to UX_MEMORY_INSUFFICIENT. This error happens line 397 of use core file ux_device_stack_initialize.c. i...
GOAL To use Ethernet + LwIP on the STM32H743 chip without cache. Explanation We don't want to use the cache when using Ethernet because when the cache is enabled and data is sent and received via DMA on the SPI line, the correct data doesn't propagat...
