Hey allI am building an application using a STM32G071RB with a DRP1M1 as ucpd 0 and a USBDP1 (old SNK1M1) as ucpd 1 and new to the STM UCPD worldIn an attempt to start from a working base, I used the DRP1M1_DRP example project as a starting point. Th...

I am trying to build an application with a SNK and DRP usbc port, using a USBPDM1 and a DRP1M1 with a nucleo g071rbI have successfully run the DRP example application, but when I try and add the functionality to my sink application stm32cubemonitor-u...

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 curious if the STM32G0x1 can manage a DRP and a UFP USB-C as a charge through application?The USBPDM1 doc mentions other IC's and possibly other breakout boards.Is there a timline on when the TCPP03-M20 and documentation will be available?Cheers...

Hey STI am building an application that has two power sources, one USB-C (27W) with the STUSB4500 controller, and an optional DC input.Because the GPIO or attach pins can be open drain, theoretically they could be used to contrl a second FET on the p...

This isn't necessarily a fix for the blank project side, but for the DRP1M1_DRP example I was missing: USBPD_PORT1_IRQHandler(); in the function UCPD1_2_IRQHandler(void), in the file "stm32g0xx_it.c"onto customizing the application (which Ill ask in ...

It looks like the priority range for cmsis v1 is 3 to -3 int's (I'm fairly new to cmsis)forcing OS_PE_PRIORITY and OS_CAD_PRIORITY to +3 and +1 the two port selection still doesn't function.Thanks @USBPD Dan for the thoughts!

Found it, I was not properly initialling USBPD_PWR_IF_Init, causing USBPD_DPM_UserInit to return an error, d'ohfollow up question, with it working under one sink port, when adding a second port or switching to DRP, it fails again, it is probably me j...

Thanks @Nicolas P When I build and run the DRP example as is the board shows up with one port, so it looks like it is open. also when I build the SNK example from the wiki the board shows up as well.GUI_Init is calledboth the DRP example and https:/...

Thanks @HFISTM The advanced section is helpful, I see there is a git with a DRP example as wellCheers
