hello guys!

does anyone have expierence with a 4x20 KS0073 LCD?
I have made an init routine
the init routine for the HD44780 together with the routine from the tutorial work fine, exept the display only uses line 1 and 3

so I made an extended init routine according the Datasheet but with this routine it look funny and only uses line 1

can anyone help me out?

HD44780 INIT routine:

	SETB	EN
	CLR	RS
	MOV	DATA,#38h	; 
	CLR	EN
	LCALL	WAIT_LCD
	SETB	EN
	CLR	RS
	MOV	DATA,#0Ch	; Display on, cursor off, blinking off
	CLR	EN
	LCALL	WAIT_LCD
	SETB	EN
	CLR	RS
	MOV	DATA,#06h	; Cursor auto inc
	CLR	EN
	LCALL	WAIT_LCD
	ret			; return

KS0073 INIT routine:

	SETB	EN
	CLR	RS
	MOV	DATA,#34h	; Function Set: 8-bit, Enable ExtFS 
	CLR	EN
	ACALL	WAIT_LCD
	SETB	EN
	CLR	RS
	MOV	DATA,#09h	; Ext. Function Set: 4 line modus, low Power=0, no blink
	CLR	EN
	ACALL	WAIT_LCD
	SETB	EN
	CLR	RS
	MOV	DATA,#30h	; Function Set: 8-bit, Disable ExtFs, 2 line(overruled by ExtFS), dot scrol, normal 
	CLR	EN
	ACALL	WAIT_LCD
	SETB	EN
	CLR	RS
	MOV	DATA,#0Fh	; Display On/Off: Display=1, Cursor=0, blink=0
	CLR	EN
	ACALL	WAIT_LCD
	SETB	EN
	CLR	RS
	MOV	DATA,#01h	; Entry MOde Set: scroll right, no shift
	CLR	EN
	ACALL	WAIT_LCD
	SETB	EN
	CLR	RS
	MOV	DATA,#06h	; Entry MOde Set: scroll right, no shift
	CLR	EN
	ACALL	WAIT_LCD
	ret			; return
