I want to interface the 128x64 graphic LCD with PIC18f4550. Since I dont have enough pins to use, I decided to go serial to parallel shift register IC.

Please suggest me a good glcd and shift register IC with circuit, which can be interfaced with the PIC18f4550.
 

it is probably simpler to use an LCD with serial interface, e.g. SPI, I2C, etc.
if you do an internet search on "LCD SPI"
 

Use SPI port expander MCP23s17 or I2C port expander MCP23017. They will save ports. Using 3 or 2 port pins we can interface 20 pin(including supply pins) GLCD. For MCP23s17, library is available in mikroc compiler.
