Single Data Line Display Operation

Hello
I'm building the Microchip energy meter project AN939 which, I believe was prototyped in India. The project has a LCD display that I think is the Deepakshi DM060 module because it is made in India and the pin count is the same as the schematic. The display is also laid out for an energy consumption meter so I think its a good bet.
The display has 7 pins, led+, Vss, Vdd, Data, W/R, CS and RD and combing through over 5000 lines of code to figure out how this diplay works is a little large. I've tried to contact Deepakshi for an op manual via email with no luck.
I have used a larger PIC16F chip in my circuit to give me another 8 bit port over the original design so that I could use a parallel LCD display as the I2C port is in use for the RTC chip.
Could anyone offer some help on how the Deepakshi LCD works so that I can change the code to drive a Matrix parallel LCD.
Thanks
Randy
