Okay. I had a bit of time today so I added the code 128 support.
You can find the code here: https://github.com/Akisame-AI/Bangle-js-2-Barcode
Next time I have some time to kill I'll create a settings page where you can add your barcodes.
Todo:
support Bangle 1
Make it actually usable (allow switching of barcodes)
Settings page
Scaling of everything
Display name of barcodes
The code is a bit long (12.8 kb, 295 lines of code) and can probably be optimized further.
For Code-128 the max length varies based on how many times you switch between codeset. If you only use numbers you can fit 24 characters (since every 2 numbers is 1 set), If you only use letters and symbols you can fit 12 characters. Every switch between the two codesets will cost you a character. If you go below 4 sets (so 8 numbers or 4 characters) it will automatically scale up.
