Hallo Leute,
habe hier seit tagen mit ein Display von pollin zu kämpfen, und es will
so richtig nichts werden.
ich verwende ein Mega16 mit 8 Mhz Taktung, angeschlossen ist es wie im
Programm was ich aus der Bascom Hilfe habe.
Den Kontrast kann ich super über eine negative spannung einstellen aber
ich bin mir nicht so richtig sicher was ich mit die Anschlüsse von Reset
und RD/E so mache.
Kann mir jemand weiter helfen wie die Anschlüsse richtig gesetzt werden
?

'some routines to control the display are in the glcdSED.lib file
'IMPORTANT : since the SED1520 uses 2 chips, the columns are split into
2 of 60.
'This means that data after column 60 will not print correct. You need
to locate the data on the second halve
'For example when you want to display a line of text that is more then 8
chars long, (8x8=64) , byte 8 will not draw correctly
'Frankly i find the KS0108 displays a much better choice.
