Hello, I find there are a note for 'GP' version LQFP64 package.In blank of UCPD, which has the number "1" .The note is: One port with only one CC Line available(supporting limited number of use cases).Is that mean only one UCPD controller( UCPD1 or U...
We use the STUSB4500 in our design to negotiate with the Host the correct current. In our design we have no connection on the VBUS_VS_DISCH pin. Because of this issue, the PD-Chip does not start negotiation. Is there any way to disable the VBUS_VS_DI...
Hi every body, current we have a problem when make compatible between USB2.0 and type C on our devices.We don't want full type C's feature yet. We just wanted our firmware to be compatible with type C cable on some laptop which have only type C conne...
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,I have integrated the CLASSB package to my application software. The HAL drivers are bypassed and custom drivers are used.In the safety checks, all the tests are passed except the Clock cross-reference check.Note: I am using default HSI clock for ...
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.
The background is I am trying to build a pass through or charge through dongle like application. Using a G0 with 2 UCPD ports, port 0 as sink, and port 1 as DRP, using the respective TCPP chipsMy goal is to have the input port 0, get the available PD...

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...
