Application for Data Writing of segment mode

When ST8012 is as a segment mode driver , you must write ‘0’ data to the part of no display, when segments are not

all used . Example: the second segment have 120 segments ,but only use 100 segments then you must write 100

data that you need and right ,then you still write 20

‘0’ data to fill the part of segments not used .Otherwise there will

be having

errors, when you don’t write the 20 ‘0’ data to fill the part of no display segments.

A summary of ST8012 in segment mode you must write the number of segments data to fill the segments.(EX : use

two ST8012 to show the 64X132, then you must write the 80X160 data to fill the segments, use three ST8012 to

show 120X200 the you must write the 120X240 data to fill the segments……)

EX:

The 44 segments is

not use but must write

44 ‘0’ data.
