I am using the USB PD driver package on an STM32G071. I have 4 ports. Two are SNK and the other two should operate as SNK unless I have a power source.First issue is DRP will not work unless you also enable CAD role toggle in the configuration. If yo...

When runnung the ADC in continuous mode, does the ADC clear the sampling cap after each read? Or does the ADC go into it's next read with the sampling cap still charged up to whatever the previous level was. Thus, potentially putting some slight amou...

In STM32CubeIDE in the SYS tab there is a checkbox called "Serial Wire". When I check it, it highlights the two ports used for serial wire debugging. But that's all it seems to do. Is this just a helper to let me know where the debug pins are?

When I make a change to the Minimum Heap Size setting in the ioc file (STM32CubeIDE 1.16.1) for G071RBTX, it results in no change to the linker file. However, changing the Minimum Stack Size here does cause a change in the liker file. What does the M...

I need to have USB PD connectivity so I am using the examples provided. There are SNK and SRC and DRP examples. However, they all use the TCPP which is also included in all of the 3 demo boards. I don't see any way to disable the TCPP component itsel...

You'll have to reselect it again each time. I think they are deleting and recreating the build folder. This breaks any notifications of change that they may have registered to retrigger the project selection. Needs a bit of work on that Eclipse plugi...

Is it possible to take your samples not when the SPI is sending data?These graphs you are showing, are they from an oscilloscope or are they the recreated signal from your ADC data?

1 input with comparator blanking looks nice! Thanks.

I have a similar situation. At certain times my device is not capable of providing a charge so it should be SNK only. When it can provide a charge it should be DRP toggling. But this driver doesn't allow that. You must pick a mode and stick with it.1...

Here is what I consider a problem.With no connections the function CAD_StateMachine_SNK is called several times after reset. However, with no connections and not toggling the port the function CAD_StateMachine_DRP is NOT called. Thus, a DRP does not ...
