T6963.c and pic16F877A
PostPosted: Mon Feb 15, 2010 3:08 am     Reply with quote
I am working on PG12864F LCD, with PIC 16F877A and compiler is CCS. I downloaded "T6963C LCD driver for Microchip 16F877" from techtoys.com.hk (which I found from this forum). My circuit is same as given by the author. I want to display ASCII characters from internal RAM only. The code I wrote is
Code:

#include <16F877a.h>
#Fuses HS,NOWDT,NOPROTECT,NOLVP,NOBROWNOUT
#use delay(clock=20000000)

#include "t6963.h"
#include "t6963.c"

void main (void)
{
GDispInit( );
FontSize= 8;
GDispSetMode(XOR_MODE | INT_CG_MODE);
GDispSetMode(TEXT_GRH_ON);
GDispClrTxt( );
GDispClrGrh( );
GDispGoto(0,0);
GDispChar(0x85);  // any ASCII char
while(1)
{}
}

Crying or Very sad
When I use this in original circuit, the LCD shows rubbish and behaviour is unusual. While same code is working in Proteus simulation. Kindly help me regarding configuration of PG12864F LCD.

Thanks

I use a similar Graphical LCD (240x128) with the T6963 driver and it works perfectly, but I used this driver code..http://www.ccsinfo.com/forum/viewtopic.php?t=19957&highlight=t6963

Also check the PIC connections to the LCD.

thanks

I have checked circuit. Circuit is ok. I want to confirm that POWERTIP
PG12864-F (128x64) uses T6963 controller or if it has some other.
Anybody working on this LCD please share his code.
