Thank you very much MikeTamu i just assumed that PBP took care of all that for me as there is no reference to it in the pbp manual.

Thanks again.

I am having similar problems trying to get an LCD working on EasyPIC3 from Mikroelectronika Board using PBP and 18F452 MCU. Although i can get the LED to blink , I cannot get the LCD to work. Can you help.

EasyPIC3 Development Board Configuration -
D4 - RB4
D5 - RB5
D6 - RB6
D7 - RB7
RS - RB2
E - RB3
RW - GND

My Code:

DEFINE OSC 8

' HARDWARE DEFINES

' Define LCD pins

DEFINE LCD_BITS 4
DEFINE LCD_LINES 2
DEFINE LCD_DREG PORTB
DEFINE LCD_DBIT 4
DEFINE LCD_RSREG PORTB
DEFINE LCD_RSBIT 2
DEFINE LCD_EREG PORTB
DEFINE LCD_EBIT 3

'-----------------------------------------------------------------
TRISA = %111111 'INITIALIZE PORT DIRECTIONS
TRISB = %00000000
TRISC = %10101001

Be sure you set HS_OSC fuse before programming your PIC

Hello,

Thanks for coming to my help once again, yes the Crystal fuse is set properly as i have a small led blink rotuine after this display , which works properly.

The LCD works with MikroBasic Compiler, But does not come on with PBP.

Because you are running at 8MHz, try including one or both of these and increasing the times as shown here

DEFINE LCD_COMMANDUS 4000
DEFINE LCD_DATAUS 100

Hi Steve,

Your inputs in a different thread solved my problem. The code was OK just that LVP fuse was enabled.

Just disabled it and there I could see what I had to on my LCD.

Thanks.
