I uploaded a video showing exactly what I am getting now. The "Volts" text no longer appears !! (note the blinking green LED in the bottom right corner, that is PIN_A0)

Hi,

I commented out the line #define FAST_GLCD, and it didn't make any difference.

I did notice though that sometimes the lcd displays partly the text "Volts:" and the text shakes for ...

To try and figure out what could be wrong, I wrote the following routine:

#include <18F46K20.h>

#fuses XT, NOWDT, PUT ,BROWNOUT, NOLVP
#FUSES NOXINST //Extended se ...

Thanks again for the response. I fixed the wiring as you suggested (4 wires), and it's still showing nothing (screen is blank)

What else could be the reason ?

GLCD ----------- PIC
4 (RS) ---------- 35 (B2)
5 (RW) ---------- 37 (B4)
6 (E) ------------- 38 (B5)
7 ------------- 19 (D0)
8 ------------- 20 (D1)
9 --------------- 21 (D2)
10 ------------- ...

I don't think that is the cause of the problem as I tried to get some text displayed on a basic 2-line LCD, and it worked perfectly fine.

I changed the fuse to HS anyway to see if it would make a ...

Thanks for the response.

I tried running a simple software on to see if I got the right driver, but screen is showing nothing (blank), not even garbage characters.

I have a graphics lcd with the controller AVANT SBN0064G. I have seen the example code provided with CCS, but it was for a different controller.

I am still out of luck finding a manufacturer selling 2 line LCDs with bigger CG ROMs...

Could anybody please help ? or give some pointers to where I can find them ?

Thanks for the fast response.
Can you please provide more details on where you got your units from ? or links to different manufacturers,, or what terms to use when searching google, or any other hi ...

I have a 2-line LCD (Powertrip pc1602f) that can only store 8 custom characters. I need to display the characters of a language other than English on the LCD (150 different characters) .

Is there a ...

Thanks alot...
It turned out I was missing the pull-up resistor. It's working now fine. Smile

I am testing it on a hardware board.

I just compiled and ran your code, and it kept B0 HIGH all the time. I then tried the following

output_high(PIN_B0);
delay_ms(500);
...

I tried reducing the delay time from 1000 ms to 10 (delay_ms(100) ) hoping that it would make it work. Unfortunately, it didn't make any difference (B1 is HIGH while B0 is LOW)

Sad

:cry ...

I just tried with pins B0 and B1 instead of A0 and A1 and it didn't make any different. I then tried replacing the section inside the while loop with the following

while(TRUE){
