@Manuel - do you have a serial ST7920?
What is the microcontroller you plan to use?
Do you want to use the GLCD in Graphics Mode (128x64) or LCD mode?
GLCD in Graphics Mode
GLCD in Graphics Mode is a write only operation which mean the implementation would require a microcontroller with 1k of RAM plus RAM for variables. An implementation could be created to use 128 bytes but this is a lot more work.
SPI mode
I have looked at the datasheet and the SPI mode is really a specific communications protocol. Not hard to implement using hardware or software SPI. Just needs a little logic to construct the protocol.
Device
Can you share the actual product you are planning to use? A URL is best.
Let me know your thoughts.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Exist any library for use this display in serial mode, in the GCB demos only see in parallel mode .
thanks.
It should be very simple to add the Serial capability. Are you referring to SPI or one wire serial?

I found this on the web.
I have a ST7920 in a temp/humidity solution. I could pull the ST7920 out and convert to to serial.
