Hi,
I have used the character lcd 40x2 and I would like to work with graphic lcd. I surveyed many of the lcd's information but still have few generic questions that I would appreciate if anybody could clarify them for me.
In my projects I have used the microchip PIC processors and they were interfaced with the lcd with 4 data lines plus 3 control lines. Most of the graphic displays use 8 data lines. Is it hard requirement or could I use the 4 lines (and transmit the data in 2 steps)?
To initialize the 40x2 I use the following code:
/* Set 8bit interface and two line display */
OpenXLCD(EIGHT_BIT & TWO_LINE & SEG1_50_SEG51_100
& COM1_COM16);
/* Wait till LCD controller is busy */
while(BusyXLCD());
/* Turn on the display */
WriteCmdXLCD(DON & CURSOR_ON & BLINK_OFF);
from this point I can display whatever string. For graphic displays do I need a specific initialization setup for each display? will the process for displaying characters be the same?
I presume that these graphic lcd's are compatible with PIC's, is this correct? Finally do these lcd's have the proper connections to connect to prototype board? Thanks
