Subject: [lpc2000] Graphic LCD to LPC2106
Hi all,
I am using graphic LCD with ARM LPC2106. I have written initialisation
code for lcd. but i am facing the problem that sometimes it is getting
initialised and some times it is not. Can anyone help in this regard? A
sample code to use graphic lcd with LPC will be helpful.
Thanks in advance.

No - no magic in the set/clr cs functions - I guess they are sampled
at the first rising edge of the clock...
But - I can't remember if the code I sent out contained the SPI
init - that's quite important...
bCPHA=TRUE;
bCPOL=TRUE;
bLsbFirstSE;
uchDataWidth=8;
uiSpiDivider = (char)(defulPCLK/20000000); //Calc 20MHz divider
uiSpiDivider = (uiSpiDivider+1)& ~1; //round to nearest even number
if (uiSpiDivider<8) uiSpiDivider=8;
if (uiSpiDivider>254) uiSpiDivider%4;
S0SPINT = 0x01;//Clear interrupt flag
S0SPCCR = uiSpiDivider;//Set SPI clock divider
S0SPCR = (uchDataWidth&0xf)<<8 |(bLsbFirst&0x1)<<6 | (bCPOL&0x1)<<4 |
(bCPHA&0x1)<<3 | 0x00a4; //force BitEnable, MSTR and SPIE - set the
rest as required
S0SPDR; //Clear the Rx register
Good luck

Hi thomas,
thanks for reply.
I am also using serial i/f to LCD. Is it needed to settle the port pins when
u set or clear it, means is it required to have delay after each set or
clear of port pin as there is no bit manipulation? what happens in your
SETCS, CLRCS code? can u please clarify more?
thanks in advance

I have recently written a driver for serial access to the ST7565S
(on a powertip PE12864LRF-001-HC1 display though). As far as I know,
the configuration is the same if You use parallel interface. As I
use SPI there is no read-back ability so I have a shadow of the
display in ram. Note that the specific settings of Bios, V5 and
electronic volume should be set according to the lcd requirements.
Here is a snippet of what I do to get it up and running - I hope it
helps.
//Write byte to the display
SPIDRIVERtx8Bit(&stSpiCfg,uchYByte);
}
SetCS(FALSE);
}
}
