well actually i had found the sample code from pommie. I tried his code in my glcd but the only thing different is the size. His glcd is 128x64 whereas mine is 128x128. I straight use his code to try in my glcd is it correct?

my glcd have 4 chip select and his glcd has 2 chip select. so it will just only on my cs1 and cs2 in my gcd right?

but then my glcd can not display even a pixel. some times it will display some but could not get exactly the same result like pommie's graphic.

Pommie

Unfortunately, when I wrote that demo code I was a little lazy and referred to some of the ports in code and so this required additional changes to be made throughout the code. I've attached a newer version of that code that should only require the #defines in GLCD.h to require modifying in order to work on different hardware. As for controlling the other two CS lines, I think the code I posted in your other thread should work.

Mike.
Edit, please see further down the thread for a corrected version of the code.

darsin

dear pommie,
are you using C18 C Compiler?
which version of the mplab are you using?

Pommie

Yes, I am using C18 on version 8.02 of MPLAB.

Mike.

i changed the chip select code.
but still nothing display in my glcd
code:
void WritePosition(void){
b_GLCD_GCS1=0;
b_GLCD_GCS2=0;
b_GLCD_GCS3=0;
b_GLCD_GCS4=0;
if (YPos>63){
if(XPos>63){
b_GLCD_GCS4=1;
b_GLCD_GCS3=1;
}
else{
b_GLCD_GCS2=1;
b_GLCD_GCS1=1;
}
}
GLCD_Write_Cmd(0x40+(XPos&0x3f)); //column=0
GLCD_Write_Cmd(0xb8+((YPos&0x3f)>>3)); //row=0
}

and please check this for me
code:
void Wait_Not_Busy(void){
TRIS_Data=0xff;
b_GLCD_RS=0;
b_GLCD_RW=1;
if (b_GLCD_GCS1==1 && b_GLCD_GCS2==1){
b_GLCD_GCS1=0;
while (GLCD_Read()&0x80);
b_GLCD_GCS1=1;
b_GLCD_GCS2=0;
while (GLCD_Read()&0x80);
b_GLCD_GCS2=1;
}

if (b_GLCD_GCS3==1 && b_GLCD_GCS4==1){
b_GLCD_GCS3=0;
while (GLCD_Read()&0x80);
b_GLCD_GCS3=1;
b_GLCD_GCS4=0;
while (GLCD_Read()&0x80);
b_GLCD_GCS4=1;
}
else{

while (GLCD_Read()&0x80);
}
TRIS_Data=0x00;
}

please help me~

Pommie

Forget about getting it to work with the 4 CS pins and just concentrate on getting it to work with 2. Make sure the unused CS pins are held low at all times.

Have you changed the #defines in the GLCD.h file?

Mike.

darsin

yes but i just added:
#define b_GLCD_GCS3 LATAbits.LATA0
#define b_GLCD_GCS4 LATAbits.LATA1
and
#define b_TRIS_GCS3 TRISAbits.TRISA0 //GCS3
#define b_TRIS_GCS4 TRISAbits.TRISA1 //GCS4

is it any other #defines need to change too??
my backlight of anod and katod already connected to the Vdd and Gnd respectively
so i don't need to connect to the port right?

Pommie

I just checked the code I posted earlier and it was the wrong version. Could a mod please delete it.

Here is the original code with the required mods so you should just have to change GLCD.h Sorry about the earlier confusion.

Mike.
PS, What happened to the edit period becoming 1 week?

Hi Eric,

See the last post of this thread. I hope it is changed as it stops silly mistakes (as above) from cluttering up the forum.

Mike.

darsin

pommie my glcd is still not working
it display nothing!
i checked all the connection and i'd grounded my cs3 n cs4...

p/s:i wanna cry~~~

Pommie

Can you post a circuit diagram?

Are you using an ICD2 or a Pickit2, if so can you pause it and see where it is stopping?

Mike.

ericgibbs

hi Mike,
Following that thread link you posted, gave me the above as at the 13th July.

I am sure its 60 mins.
