Edp-i lcd module evaluation & development platform jem innovation inc. 125 stearman court erie, co 80516.
The edp-i has been designed for evaluating lcd modules without having to lay out your own design. It provides pinouts for the most popular modules in the industry and a standard keyboard interface. It will interface to most modules that use the industry-standard hd44780 controller (or equivalent), r...
Top pinout (connector t1) this is a relatively standard layout. If your module does not provide a negative voltage on pin 15, then install a shunt on j1. If it does output a negative voltage on pin 15, you must remove j1 and wire a and k terminals to the header labeled “a” and “k” using external wir...
Bottom pinout (connector b1) this layout exists solely to make things complicated! Note that the pins 1 - 14 run right-to-left but pins 15 and 16 are on the right end. Additionally, pins 15 and 16 may be reversed! Note: some modules with a bottom connector will need to use the t1 pinout! Check your ...
Other pinouts we have tried to address the majority of the pinouts that we’ve seen. However, there are far to many variations for one board to cover them all. The edp-i should be able to handle any module that supports the pseudo-standard 7 bit interface if you can solder up the correct wires. Backl...
Edp-i general operation the edp-i interfaces to the industry standard “at” style keyboard using a ps/2 sized connector and provides a ‘line’ based editor. This allows users to enter/edit one line without disturbing other lines on the display. The exceptions to this are: the cursor will wrap-around t...

The user will have the option to store the new setting as the power-on default. Warning: if you save th...
