Hello, I want to try to use PTP in my project, but the lack of documentation took me into a dead point. I'm currently using an STM32H755 which support the protocol.I have a lot of question but as first thing I want to understand the faesability of th...
Hello,I am programming a USB device from scratch (for learning purposes) on a STM32F7 board.It is a simple HID mouse.Everything works great in the enumeration, my device is correctly recognized by the host (Windows PC) as a mouse. I've chose to use a...
After testing P-NUCLEO-USB002 kit with it's embedded demonstration example I try to use different example from en.STSW-STUSB010 examples- it seems like non of them support UART interface (CLI) as in P-NUCLEO-USB002 embedded demonstration example. my ...
Hello,I am working on Nucleo-h745ziq board. I initialize the azure-rtos h7 package, enable the Usbx and thread parameter .According the project that given in cubemx of Ux_Device__CDC_ACM accordingly I initialize the parameter only difference is that ...
Hi,Please note my hardware design background is weak. I'm confused between the design in AN4879 and the schematics of STM32H7xxx-Disco, as shown below. Your help is much appreciated.

I want to MDMA reqests occure on only calling HAL_MDMA_GenerateSWRequest(..). But we have also a not wanted request on enabling MDMA using HAL_MDMA_Start(..). Then the codes if(hmdma->Init.Request == MDMA_REQUEST_SW) { /* activate If SW req...
I am giving it what I think is a reasonable waveform with < 2ns monotonic edges. It all works but I would like to make sure.I posted waveforms herehttps://www.eevblog.com/forum/microcontrollers/32f4-is-there-a-spec-on-the-50mhz-clock-from-the-eth-phy...
I have 4 x STM32F373CCT6 on a custom board connected to a USB hub, all of which are clocked from a 3v3 24MHz oscillator ( rather than putting down 5 crystals and all the caps ). I have the 1k5 resistor pull up on the D+ line. when the board is power...
