I'll use fastlcd.exe to prepare fonts. So, when I finished the font design, fastlcd will save a data payload for the font. Do I have to seperate this data payload for two driver chips? If yes how can I do that?

I don't have latest version of FastLCD. But the one I have gives the output for VB, and not for C.

* On the other hand how should I drive wave forms? I'll be getting digital data samples for waveforms from power meter chip.

Once you are able to show some data on the GLCD, you can turn on/off the individual pixel on the LCD. Then you just have to use your imagination/creativity how you want to display it.

* The GLCD connected with 8-bit parallel data bus to microcontroller. As I said before, my GLCD is a secondhand module. there is no brand on it. So, I could not find a datasheet. Timings are undefined for me.

I believe there are 2 types of Standard 128x64 GLCDs. Pin 1 is GND, and in the other Pin 1 is VCC. So also there is a difference in other pins also. But basically there are just 2 types of GLCDs.

Type 1
1 Vss
2 Vdd
3 Vo
4 D/I
5 R/W
6 E
7 DB0
8 DB1
9 DB2
10 DB3
11 DB4
12 DB5
13 DB6
14 DB7
15 CS1
16 CS2
17 RST
18 Vee
19 A+
20 K-


Type 2
1 Vdd
2 GND
3 Vo
4 DB0
5 DB1
6 DB2
7 DB3
8 DB4
9 DB5
10 DB6
11 DB7
12 CS1
13 CS2
14 RST
15 R/W
16 D/I
17 E
18 Vee
19 A+
20 K-

You can easily find the type of LCD, by checking the pins of IC7660 (used to generate Vee (-5V)), to the GND pin on the connector. Get the datasheet for IC7660

If you have an LCD that is not the standard 128x64, then you might need to find the datasheet for it.
Read/Write Timings are almost the same as the standard 16x2 LCD. Remember that whatever you write into the LCD for CS1, it will be displayed on the left half of the LCD. and with CS2 it will write on the Right had side of the display.
