應該得，但有些LCD的正負極的安排是反接的，如果真係反接的就用吾到，因為我的PCB的1 &16腳係負2&15腳係正5V，另外安裝孔也未心arm位

「
It looks as if the -2A1 revision of the LCD is out of production. http://www.trulysemi.com/eng/prod.asp?typeID=26&search=no
lists a -3 and a -17 revision in production. For both the -3 and -17 they specify that the controller is an SPLC780. The 780 at the end is a first hint that this might be a HD44780 compatible controller. Alldatasheet has a datasheet for an SPLC780D at http://pdf1.alldatasheet.com/dat ... 8/ETC/SPLC780D.html

藍色果隻原來係4x20
here is the spec for it.   page 4 有寫腳位定義.
