pic16f877 graphic display
Hi,
I'm afriad without much more information, I can be of little help here. Most (but not all) graphic LCD's have an in-built controller, with display RAM and sometimes a font generator. Could you please specify the LCD part number. Also, search google for the datasheet, that'll have the pinout. The pinout really depends on the actual LCD, there is no real 'standard' apart from the fact they usually have D7-D0, for parallel interfaces, plus R/W, C/D, and a strobe line, usually 'E'.
For a 192x64 I'm only aware of two possible contorller chips: SED1330, and the T6369C. Both have a very similar interface. It is also possible for a 192x64 to use the KS0108, but I doubt it, that contorller has no font ram, and although simple, can be troublesome. All the above can be controlled with a PIC, no problem. The only real limitation is memory, as larger displays require you to store bitmaps, 192x64 = 12kbytes.
Find the part number (on the LCD), oogle it, and try and find the datasheet, that has all the info you need. Most even give you initialization sequence, and the appropriate commands.
