Click to expand... hi, Using 8 bit wide data to the LCD means that a full 8 bit byte can be written to the LCD controller. With 4 bit wide data, the 8 bits of data are written in two successive 4 bit bytes. The 8 bit is overall faster but requires 8 PIC pins, the 4 bit uses only 4 PIC pins. OK.? Last edited: Mar 14, 2010
