Hello,I would like to ask a question, if it is possible to access UCPD monitor via USB-UART bridge? I am following tutorial AN5418, with nucleo G0B1RE and SNK1M1 shield. Everything works fine when I use st-link, but when using uart bridge I dont see ...

Hello dear ST community,I am making a PPS (sink) application based on NucleoG0B1RE + SNK1M1. As noted in various resources, the TCPP01-M12 doesn't include OCP protection. However, the USB Power Delivery Specification R3.2 on usb.org, strongly recomme...

Hi,I am currently working with the documentation of TCPP01-M12. I have find some small mistake in the table of recommended capacitor C3. The part codes are switched. Also it seems that the GRM188... 0603 package capacitor is obsolete nowadays. Could ...

Hello,I am trying to make my own custom USB PD application on NucleoG0B1RE + SNK1M1 hardware.I want to change dynamically the SNK PDOs in my application (it should be possible according to this post). Since I want it to be working with various Source...

Dear community,I have deployed a basic USB PD sink application according to AN5418 on NucleoG0B1RE + SNK1M1 hardware. I have also implemented a USBPD_DPM_RequestMessageRequest() function inside usbpd_dmp_user.c (according to this post), so the user ...

I am also experiencing this error in CubeIDE version 1.14.0. The live variable sometimes initialize to nonsensicaly high values and I have to stop the debug and start again or reset the board.

Yes they are ticked in CubeMX according to the AN5418. The point is that using same software it all works when TX and RX fed to st-link and then from st-link to PC but it doesn't work when TX and RX are fed to uart-usb bridge from different vendor. I...

Thank you for your reply @MROUV.1.Is it the custom OCP solution using the TCPP01-M12 and current sense amplifier with alert pin and another mosfet also feasible, or is switching to the TCPP03-M20 the best path forward in this case?If I move to the TC...

Hello@LLECH.1,You are right after playing with it for a while it seems it would be possible to define multiple PDOs based on the attached PD3_2 Specification. According to the table I could make multiple APDO definitions for 9VProg, 15VProg and 20VPr...

Hello @Nicolas P. ,providing the SNK supported PDOs at the start in pdo_defs.h would also make sense to me. The problem is I dont know the SRC PDOs priory. As this is the case I would like to declare for my 100W SNK general APDO as 3300mV-20000mV max...
