16x2 lcd lm016l commands

where can i get 16x2 lcd lm016l's total commands

Seems that this display uses an HD44780 controller.
Now for the commands you've to check the datasheet of the controller, e.g. here:
https://www.sparkfun.com/datasheets/LCD/HD44780.pdf
https://users.ece.gatech.edu/~hamblen/UP3/HD44780u.pdf

Hi,
Take a look at:
**broken link removed**
This is the set of commands for all LCDs using HD44780 controller.
Hope it helps.
Tahmid.

you may get some code from yhis programe pls gothrough it (Hitachi LCD HD44780 module)
LIST P=16C84;f=inhx8m
; these are directives for the programmer to set various fuses in the 16C84

_CP_OFF equ H'3FFF' ;code protect off
_PWRTE_ON equ H'3FFF' ;Power on timer on
_WDT_OFF equ H'3FFB' ;watch dog timer off
_XT_OSC equ H'3FFD' ;crystal oscillator
__CONFIG _CP_OFF & _PWRTE_ON & _WDT_OFF & _XT_OSC
;configure directive

w equ 0 ; destination numbers.
f equ 1
same equ 1

z equ 2 ; status bits
zero equ 2
c equ 0
carry equ 0

ind equ 00 ; indirect register f0
pc equ 02 ; program counter f2
status equ 03 ; status register f3
fsr equ 04 ; file select register.
; contents are used as an address
; when you operate on f0
porta equ 05 ; port a I/O register f5
portb equ 06 ; port b I/O register f6


LCDcontrol = porta ;Control lines to LCD
RW = 2
RS = 1
E = 0
LCDdata = portb
count = 3 ;Number of characters
; LCD commands follow
wide = b'111000' ; 8 bit interface
narrow = b'101000' ; 4 bit interface

clear = 1 ; clear display
home = b'10' ; cursor home

ns_dec = b'100' ; no shift, decrement
s_dec = b'101' ; shift, decrement
ns_inc = b'110' ; no shift, increment
s_inc = b'111' ; shift, increment

dispon = b'1100' ; display on, cursor off, blink off
dispoff = b'1000' ; display off
cur_line = b'1110' ; line cursor
cur_blk = b'1111' ; block cursor

curR = b'10100' ; move cursor right
curL = b'10000' ; move cursor left

movR = b'11100' ; shift display right
