Can't get LCD to work on Easypic 7 board using Pickit3 programmer

[dbachman]

Can't seem to get this to work on Port B..


DEFINE LCD_DREG PORTB
DEFINE LCD_DBIT 0

DEFINE LCD_RSREG PORTB
DEFINE LCD_RSBIT 4

DEFINE LCD_EREG PORTB
DEFINE LCD_EBIT 5
DEFINE LCD_LINES 2
DEFINE LCD_BITS 4
DEFINE LCD_COMMANDUS 2000
DEFINE LCD_DATAUS 50

ADCON0 = %00000000
TRISB = %00000000
worda var word
worda = 12345

Lop:
pause 50
LCDOUT $fe, 1,"DEC =", dec worda
pause 1000
LCDOUT $fe, 1,"Value = ",dec worda,".",dec1 worda
pause 1000
LCDOUT $fe, 1,"Value =", dec worda,".", dec2 worda
pause 1000
LCDOUT $fe, 1,"Value =", dec worda,".", dec3 worda
pause 1000
LCDOUT $fe, 1,"Value =", dec worda,".", dec4 worda
pause 1000
LCDOUT $fe, 1,"Value =", dec worda,".", dec5 worda
pause 1000
GOTO LOP

END

Can someone take a look and see what I am doing wrong? Thanks Don

Not sure which processor you are using but, sometimes the default config registers set port B to default to analog and not digital. I see NO configuration statements.

I am using pic 18f45k22...I can program the pic but the lcd doesn't display..trisb was set for the outputs..
Not sure why this doesn't work. It compiles and works ok on 18f2550 not using the Easypic v7 board...

I do not see where you are setting the ANSELx registers. They default to digital input buffer disabled. There are quite a few more registers added to the "K" series processors. Read the Spec sheet.

Thanks Dave, I think you are right....I have downloaded the pdf dataset and going over it...I was treating the 18f45k22 like I would a 18f4550 which is not correct..I will post back when I get this working..
Thanks Dave....
