Hi everyone,
we need a bit of help with this one as well ...
works fine but what shown on the picture should be a full 888888888 display
i.e all the "g" segments are missing.
We think it could be a faulty Anode Driver 1820-1029 and possibly the 11th pin
which should drive the g segment, but any advice or suggestion about what
to measure and what to expect is welcome !!
thanks in advance !!
