![]() Use the ASCII table to convert these initials into ASCII and then into binary code to then generate a barcode matching those initials. So to produce our own simplified bar codes all we need to know is convert each digit of the actual number into binary (using 4 digit binary codes, aka a nibble) DecimalĪdapt this script to ask the end-user to enter their initials. The following binary code “1110” however consists of a large black line (as thick as 3 lines) and a thin white line. So the following binary code “0101” consists of a thin white line, a thin black line, a thin white line and a thin black line. Read serial port with simple file operations from python: f open ('/dev/ttyACM0') print f. ![]() ![]() Now your 3310g is in serail emulation mode, note new /dev/ttyACM0 or /dev/ttyUSB0 device. On a barcode the pattern made using black and white lines is in fact binary code! A black line represents a 1 and a white line a 0. You should try using zbar and a PyUSB, scan 'USB Serial'-mode barcode, then 'Save' barcode to make this setting permanent. Though there are different standards to produce barcodes, they all follow a similar approach based on binary code! Did you know? For this challenge we are investigating how barcodes are produced. ![]()
