Here is some of the text we might want to show on the HD44780 based display:

  • (Device needs setup) “Please connect to my open WiFi called Pi”
  • (No internet connection) “Please make sure I have an Internet connection or re-run setup”
  • (Out of space) “Please make sure my USB stick is working and has enough free space”
  • (Syncing) “Please wait while I synchronize [x/100%]”
  • (Unknown error) “I’m sorry, an unrecoverable error occurred. Please reset me”
  • (All good) “Everything is working! [show dashboard stats here]”

Take a look at Material guidelines to improve the text

On the e-ink display we want to display:

A menu with (4) physical buttons:

  • Select next
  • Select previous
  • Confirm selection
  • Show QR code connection string

Users will be able to choose a product and upon confirmation get a QR code displayed for payment.

Prototype

As pictured, or alternatively in a long-side-up configuration with buttons at the bottom. More space would be available for text above and below the QR codes, e.g. "Please scan to pay".
