Pinecil mod detection

• What kind of change does this PR introduce?

Expanding the shown type in the debug menu to indicate if VBus is connected or not.
This allows user to check the VBus mod presence on a Pinecil for use over 21V

• Other information:

Would love any pinecil testers (both modded and not).

It should show PD W. VBus if you have not done the mod, and PD No VBus if you have done the mod.

Updated to firmware 2.16.FB29770 06-02-22

using USB-c to usb-C cable to PC. because that has enough power to view menu, selected minus long hold, then + to scroll through debug menu. I can see other settings like HW, time, move, rtip, ctip, CHan, Vin, ACC, PWR DC, Max, Hall
and nothing else,
It does not show me PD setting at all.

Flashed the Sciencil, registers PD No VBus, main pinecil registers PD W. VBus

[River-Mochi]

Connected to Pinepower USB-C 65W port.
menu correctly shows PWR PD No Vbus (because I cut the trace & modded pinecil to 24V)

might be better if it said sometihing more intuitive like
PWR DC24V Mod and PWR DC21V NoMod

[River-Mochi]

Also tested by connecting old google pixel 2 cellphone (PD device) by usb-c cable to Pinecil and shows same PD No Vbus correct message as my pinecil's are 24V modded.

Also tested connecting usb-C to anker usb-c 36W charger.

All worked correctly and displayed same message indicating that my Vbus is not connected to PD and I have a successful cut of my trace.

@Ralim
Good morning Sir,
I am having a question regarding this implementation.

1. Should this work for all models?
2. What exactly is VBus for? What does it do?

On my TS80P I am having an issue when browsing the debug menu and reaching PWR it states: PD No VBus and immediately restarts itself. 🤷‍♂️

Why is that?

[Ralim]

The mod is for Pinecil only, Miniware TS80P should show No VBus

VBus is a pin on the FUSB302 used for USB-PD negotiation that does not need to be connected and infact can cause issues if it is connected and you connect > 21V to the input on the Pinecil. So this is for detecting if VBus is actually wired up or not.

The iron should not restart itself though.

I cant reproduce the restart here? :/

[discip]

Could this be related to my power supply?

iron	Firmware Version	ACC	Power Supply
TS80P	https://github.com/Ralim/IronOS/actions/runs/1831832347	LIS2DH12	Anker Nano II 45W

[Ralim]

Shouldn't be related; does it restart any other times (not in the menu) ?

[discip]

Nope!

Or is it due to PPS?
Or the custom bootloader? 😵

[Ralim]

Shouldn't be any of those 😓
I cant reproduce it.
Could you check if its timing related? Like; if you enter the debug menu immediately does it crash, or is it if you leave it there for a while?
Does it crash on showing that text or when you next push a button?

[discip]

1. It does crash almost immediately (~50ms).
2. I do not need to press any button to let this happen.

I just tried it using different plugs:

Power Supply	tech	state
Anker Nano II 45W	PPS	resetting
UGREEN 65W GaN Charger	fixed value	not resetting

[Ralim]

Ahh wait, its probably because the TS80P does the software I2C (slow) and PPS needs the timings :/

[discip]

Since this is not needed for the TS80P anyway, I recommend limiting this exclusively to the Pinecil, instead of working this out. 😊

What do you think?

[Ralim]

Made pr to mask check.
I wish Miniware just had some brains in their design team :/ but yeah fair enough
