Barcode code39 details:
The code39 format contains for each characters 5 bars (black stripes) and 4 spaces
(white). Three elements are wide and six elements are small. The ratio between wide
and small is 3:1. The characters are separated by an inter-character gap, which is a
small space.
Output connection D1 transmits code39 data black = high.
Output connection D0 transmits code39 data black = low.
