hi all again,

i see that a lot of you having problem to write on the nokia lcd using the pic16f628a.

i'm also stragling to do it and i havent been able to fix my problems.

i'm trying to use the following files from the page http://www.picbasic.co.uk/forum/cont...Nokia-3310-LCD but no luck.

a very simple code i'm trying to display is the following.

Code:
DEFINE OSC 4

@ DEVICE pic16F628A, INTRC_OSC, WDT_OFF, PWRT_OFF, BOD_OFF, MCLR_ON, LVP_OFF, CPD_OFF, PROTECT_OFF 

include "modedefs.bas"
include "LCD_3310.pbp"


        TRISB = %00011100        			'portB configuration  0=out 1=in
        TRISA = %10100000        			'portA configuration
        PortA = %11100000        
        CMCON = 7                		
        VRCON = 0                		
        INTCON = 0              

OPTION_REG=%00000111   					'weak pullups on, TMRO prescale = 256
                                                
Lcd_DC      var PortB.0 
Lcd_SDA     var PortA.3
Lcd_RST     var PortA.4
Lcd_CLK     var PortA.2

start:

@ PrintStr  0,0, "I love being"
@ PrintStr  0,1, "able to print "
@ PrintStr  0,2, "so easily!"

goto start
i will post later on the full code using the pic16f628a. It is seems that is been compiled but i dont see anything on the screen. I have checked connection and everything is ok.

I have also checked the nokia lcd with a circuit that work and didnt see a problem.
