Conections for DAtainternational DG-12864-19 , and negative voltage generator.
Here my idea , the goal is to make an external LCD bay , that will include an inverted Grafic LCD (128 x 64 ) from DataInternational , the model is
G-12864-19-S2FBLY , that needs some extra negative tensions to work properly (lcd Driving and Contrast) this shematic can be easyly adaped to other LCD modules by simply editing the schematic in order to the pinouts of your LCD , the shematic is in EAGLE format (http://www.cadsoftusa.com)
For now i've only sensibilized the PCB and ill made it tomorow , as i have some time ill post some more pictures of the progress
.
