RCM3700 and 122x32 LCD Graphics Display

Rabbit

Has anyone successfully used a 122x32 graphics LCD with any of the RCM3700 modules?

I am trying to interface a 122x32 LCD which uses the SED1520 driver (same instruction set as the Rabbit keypad/display unit) but have so far been unsuccessful.

I have connected the LCD pins to the RCM3700 prototyping board exactly as the Rabbit keypad/display unit connects to the prototyping board (data, A0, RW, E1 E2 etc) (except, of course the keypad connections, since I do not intend to use a keypad). I was hoping to use the available graphics library (which should work with the Rabbit keypad/display unit).

I wish Rabbit had an inexpensive LCD display module available. The keypad/display unit is overkill for my application and is too expensive.

Thanks in advance for any help.
