We've been working on QR detection and decoding for our upcoming @Keycard_ hardware wallet!
We have forked quirc (https://t.co/QJbQuax3ve) and set to work on our main task, which is to optimise the amount of RAM QR decoding will use.
Our objective is to find a way to capture and decode QR codes in all of our supported scenarios (including those that involve large dynamic QR codes!) using less than 500kB of RAM 💪
Working towards this goal, this week we have decided to
👉 not use dynamic memory allocation
👉 use square camera frames because QRs are square, innit 😉
It turns out that doing these two things reduces RAM usage by 25%
More work to do, but we have made the first steps in our quest to reduce QR decode RAM usage!
