Barcode Symbologies

Do you have a list of the Code 39 bit pattern?

A Code 39 symbol consists of nine elements (bars or spaces) of which three are wide and six are narrow. Here is a Code 39 bar pattern array in C-style format. The sequence is: character, followed by the data for wide and narrow elements (alternating bars, spaces).

unsigned char c39_bp[44][10] =
