hi fystyles, I am very grateful for the qr code scanner that you have created. I want to ask what are your steps to make a qr code scanner, what are the theories and steps that need to be considered to make each formula? I happen to want to add a function to be able to read 2d barcode scanner type pdf417, may I know? thank you

I am sorry for being late reply. I am not the originator but I modified the code. You can open the originator's github.
