Once the initialization is complete, the LCD can be written to with data or instructions as required. Each character to display is written like the control bytes, except that the R/S line is set. During initialization, by setting the S/C bit during the move cursor/shift display command, after each character is sent to the LCD, the cursor built into the LCD will increment to the next position (either right or left). Normally, the S/C bit is set (equal to 1) along with the R/L bit in the move cursor/shift display command for characters to be written from left to right (as with a teletype video display). One area of confusion is how to move to different locations on the display and, as a follow-on, how to move to different lines on an LCD display. Table 17.3 lists how different LCD displays that use a single 44780 can be set up with the addresses for speci c

LCDs
character locations. The LCDs listed are the most popular arrangements available, and the layout is given as number of columns by number of lines. The ninth character is the position of the ninth character on the rst line. Most LCD displays have a 44780 and support chip to control the operation of the LCD. The 44780 is responsible for the external interface and provides suf cient control lines for 16 characters on the LCD. The support chip enhances the I/O of the 44780 to support up to 128 characters on an LCD in two lines of eight. From the table, it should be noted that the rst two entries (8 1 and 16 1) only have the 44780 and not the support chip. This is why the ninth character in the 16 1 does not appear at address 8 and shows up at the address that is common for a two-line LCD. I ve included the 40-character by 4-line (40 4) LCD because it is quite common. Normally, the LCD is wired as two 40 2 displays. The actual connector is normally 16 bits wide, with all 14 connections of the 44780 in common, except for the E (strobe) pins. The individual E strobe lines are used to select between the areas of the display used by the two devices. The actual pinouts and character addresses for this type of display can vary among manufacturers and display part numbers. Note that when using any kind of multiple-44780 LCD display, you probably should display the cursor of only one of the 44780s at a time. Cursors for the 44780 can be turned on as a simple underscore at any time using the enable display/cursor LCD instruction and setting the C bit. I don t recommend using the B (block mode) bit because this causes a ashing full-character square to be displayed, and it really isn t that attractive. The LCD can be thought of as a teletype display because in normal operation, after a character has been sent to the LCD, the internal cursor is moved one character to the right. The clear display and return cursor and LCD to home position instructions are used to reset the cursor s position to the top right character on the display. An example of moving the cursor is shown in Fig. 17.12. To move the cursor, the move cursor to display instruction is used. For this instruction, bit 7 of the instruction byte is set, with the remaining 7 bits used as the address
