LCD 16 characters inline: only first 8 work

[mister_e]

you need to treat it as a 2X8 display.

      LCDOUT $FE,1,"12345678",$FE,$C0,"ABCDEFGH"
Spin: Goto Spin

about now?

pssst! read carefully the LCDOUT section of the manual.

Hi,
please try this:

' Set LCD Data port
DEFINE LCD_DREG PORTB
' Set starting Data bit (0 or 4) if 4-bit bus
DEFINE LCD_DBIT 4
' Set LCD Register Select port
DEFINE LCD_RSREG PORTB
' Set LCD Register Select bit
DEFINE LCD_RSBIT 1
' Set LCD Enable port
DEFINE LCD_EREG PORTB
' Set LCD Enable bit
DEFINE LCD_EBIT 0
' Set LCD bus size (4 or 8 bits)
DEFINE LCD_BITS 4
' Set number of lines on LCD
DEFINE LCD_LINES 1
pause 100
lcdout $fe,1,"Hello"
end


LCD Connection
Pin1=Vss: connect to ground
Pin2=Vdd: connect to Vcc=5V
Pin3=Vo: connect to middle pin of the POT(20K) to control brightness
Pin4=RS(register select): connect to micro pins that specify in the software(RB1)
Pin5=RW(Read/Write): connect to ground because we want to only write
Pin6=E(Enable): connect to micro pin that specify in the software(RB0)
Pin7 to 10: No connection
Pin 11 to 14: connect to RB4 to RB7
Pin15: connect to Vcc with a resistor(100 or 200 ohm resistor is good)
Pin16: connect to ground.
pin 16 and pin 16 are for backlights

the other two pins of pot should connect to VCC and ground and you should connect the MCLR with a 4.7K or 10K resistor to the VCC.

in your program you define the 2*16 lcd but you should do this:
DEFINE LCD_LINES 1

First things first:

thanks for the help..I had the manual not in my vicinity.

Now the LCD works...and I can scribble on my LCD impressing one of my kids, hihi!
Will test your example Amindzo!

Hasta la vista companeros!

Hi Amindzo,

the change to "Lines 1" instead of Lines 2 doesent work,the LCD overwrites its own charaters.
But man I´m glad it works !

Next i´m into is the command "Pulsin" or "count"

Those are nice, if you want my opinion, use PIC internal Timer in counter mode. Sure you're limited to use dedicated pin but it's much accurate.
