I need to scan a QR code via the command line when a script is run. My current setup is an epaper display with integrated 4 buttons. So far I have each button programmed to run a script to change images on the epaper. easy. But now I want to be able to attach a camera to my Pi zero and scan a QR code by using one of the buttons that activates a scanning script.
- Would a pi zero be able to do this or do I need a Pi3 instead?
- Can I scan a QR code via the command line reliably? I'm scanning blind as I have an epaper display and not an LCD. Will I have issues?
- After scanning the QR code, I need to pass this data into a nodejs script and it should output my calculated result on the epaper display. What software would be most ideal for scanning?
