// Segment bit positions for 7 Segment display using the DVD538A mapping for PT6964
// Modify this table for different 'bit-to-segment' mappings. The ASCII character defines and the FONT_7S const table below 
// will be adapted automatically according to the bit-to-segment mapping. Obviously this will only work when the segment
// mapping is identical for every digit position. This will be the case unless the hardware designer really hates software developers.
