I'm using a NUCLEO-H743ZI2 board and following the examples in Ux_Device_CDC_ACM targeting H723 and Ux_Device_HID_CDC_ACM targeting H747, but no data ever comes in and fails to match the "ux_utility_memory_compare" function in "usbx_cdc_acm_read_thre...
Could someone tell me, what i do wrong?I made an external bootloader on QuadSPI chip and it works well with applications that do not use a FreeRTOS!But, I need to make the application that use FreeRTOS and it is don't work properly! The steps that I ...
Hello all,While searching online, I came across this specification regarding USB FS:For full-speed communications, the data rate is specified to be 12 Mbps +/- 0.25%.I've decided to test this specification by connecting a STM32F415 MCU to a PC using ...
Hello!I'm trying to create a USB composite device with 2 registered classes DFU and CDC ACM, using USBX middleware on stm32u585 mcu.I was going through those two examples on git:STM32CubeU5/Projects/B-U585I-IOT02A/Applications/USBX/Ux_Device_DFU/STM3...
I have had an sdmmc card running fine using STMCUBE MX with the default pins PC9,PC10,PC11,PC12,PD2 and PB13 with the SDCARDCARD DETECT PIN being allocated to a free GPIO Input (PC8) but when I reallocate the pins to free up the ULPI interface - prim...
I would like, if possible to use the 64 pin package in my design. The problem is that I need a CAN bus and would like to program the chip straight from USB (with potentially needed level shifting?) with the DFU I've heard so much about. I can move CA...
I am trying to configure the STM32L476 as a USB Microphone, my input is an analogue microphone through the ADC. I configure the device as an Audio class, at first my computer found it as a speaker, so I search about it and find that I need to redefin...

I am using multiple devices which access I2C communication channel. Can anyone suggest me what should be the preferred method to avoid clashes between the devices.The devices are placed across different RTOS tasks.
