unsigned int i;
for(i=0;i<j;i++)
{
}
}

void main()
{
P0=0x00;
P3=0x00;
P2=0x00;

RST=0;
delay(1);
RST=1;

LE=0;
P2 = 0x3e | 1 << 0; EN = 1;delay(1);EN = 0; // initialise the GLCD | DATA appears

P2 = 0xb8 | 0x00; EN = 1;delay(1);EN = 0; // select the page (PAGE 0)

P2 = 0x40 | 0x00; EN = 1;delay(1);EN = 0; // select the column (COLUMN 0)
LE=1;
P2=0x05;// enble cs2,rs=1,r/w=0
EN = 1;delay(1);EN = 0;

P2 = 0xaa;EN = 1;delay(1);EN = 0; // load data in data register | give H-L to En
while(1);


}

I suggest you using **broken link removed**compiler for 8051. It have ready library for graphic lcd interface. It working properly and accurate.
