Hello, this is Phat’s extension for Microbit. It’s called 2of5font This will be an extension for rendering numbers on the microbit screen in 2of5 mode. This is most commonly seen in basic one-dimensional barcodes such as the ITF barcode, and is an extension inspired by all the two-fifth family of one-dimensional barcodes, especially the ITF barcode.

Hello, I upgraded the extension by overhauling several codes and adding negative number support and changing the 2of5 code database from a string list to a buffer that stores hexadecim in two consecutive digits containing the 2of5 code stored in binary numbers.
