Code Instruction Set for Character Type LCD Modules

 

Instruction	Code										Description
	RS	R/W	DB7	DB6	DB5	DB4	DB3	DB2	DB1	DB0
Clear display	0	0	0	0	0	0	0	0	0	1	Clear display and return the cursor to home position (Address 0). Sets I/D=1 of Entry Mode
Return home	0	0	0	0	0	0	0	0	1	*	Return the cursor to the home position (Address 0). Also return the display being shifted to the original position. DD RAM contents remain unchanged. Set DD RAM addresses to zero.
Entry mode set	0	0	0	0	0	0	0	0	I/D	S	Set the cursor move direction and specifies or not to shift the display. These operations are performed during data write and read of DD RAM/CG RAM. For normal operation, set S to 0.
Display On/Off control	0	0	0	0	0	0	1	D	C	B	Set On/Off all display (D), cursor On/Off (C), and blink of cursor position character (B)
Cursor of display shift	0	0	0	0	0	1	S/C	R/L	*	*	Move the cursor and shift the display without changing DD RAM contents
Function set	0	0	0	0	1	DL	N	F	*	*	Set interface data length (DL), number of display lines (N) and character font (F)
Set the CG RAM address	0	0	0	1	MSB          ACG					LSB	Set the CG RAM address. CG RAM data is sent and recievd after this setting
Set the DD RAM address	0	0	1	MSB                 ADD						LSB	Set the DD RAM address. DD RAM data is sent and recievd after this setting
Read busy flag & address	0	1		MSB                 AC						LSB	Read Busy flag (BF) indicating internal operation is being performed and read address counter contents
Write data to CG or DD RAM	1	0	MSB                                                LSB								Write data into DD RAM or CG RAM
Read data from CG or DD RAM	1	1	MSB                                                LSB								Read data from DD RAM or CG RAM
S=1 : accompanies display shift when data is written for normal operation set to 0											DD RAM : Display Data RAM
I/D = 1 : Increment						DL = 1 : 8 bits					CG RAM : Character Generator RAM
I/D = 0: Decrement						DL = 0: 4 bits					ACG : CG RAM Address
S/C = 1 : Display shift						N = 1 : 2 (1) line					ADD : DD RAM Address corresponds to cursor address
S/C = 0: Cursor move						N = 0 : 1 line					AC : Address Counter used for both DD and CG RAM addresses
R/L = 1 : Shift to the right						F = 1 : 5x10 dots					B : 1 = On, 0= Off (Blinking cursor)
R/L = 0: Shift to the left						F = 0: 5x7 dots					C : 1 = On, 0= Off (Cursor)
BF = 1 : Internally operating											D : 1 = On, 0= Off (Display)
BF = 0: Can accept instruction											*= Don't care

* The module automatically performed initialization when powered on (using internal reset circuit). The following instructions are executed during initialization:

Power On Timing Diagram

Note: When the above power supply condition is not satisfied, the internal reset circuitry does not operate correctly. In this case perform the needed initialization by sending function set instructions thrice from MPU after turning the power on. For example, to designate an 8-bit data length, set the following instructions thrice.
