Room77: Button Functions and Menu

[rootzoll]

The LCD should over the buttons show the meaning of the buttons.

Those can be flexible based on if the user already entered an amount or not.

If a amount was entered:

A: CANCEL
B: Bitcoin (on-chain)
C: Bitcoin Lightning

If no amount was entered yet it could be a navigation or other options (to be discussed):

A: Info (Node & POS info)
B: History (to check latest payments for disputes)
C: Next Infoscreen/Menuscreen

This returns to the concept of keeping the device simple enough for a nocoiner employee. Maybe those options should be pushed to physical features, rather than clutter the screen (red cross on button A, Green tick on C)? "TO RESET PRESS A" could be then changed to "TO SWITCH BETWEEN MN/LN PRESS B"

What do you think about following concept:

With amount: A / Cancel: reset C / OK : create invoice (show new screen) |-- Lightning Invoice ( Button A) |-- Onchain Invoice (Button B)

without amount: Button A / B: same behavior like with amount B / Menu: open menu screen

Regarding the menu function I wonder which information really makes sense at the POS. Do you have an example with an use case?

I am a bit hesitant about the extra new screen ... but I think it makes sense to give the bar staff clear info and not to have them learn the meaning of buttons. If "on-chain" is not available it can skip that screen and jump directly to the QR code.
