I'm using the chipkit uno32 and have a Color LCD shield(EPSON). How would i be able to make the color_LCD_library works in the chipkit. I'm getting alot of errors on the Pins. please your help is very much appreciated

The lib uses direct port manipulation it needs to be ported to chipkit.

For instance in colorlcdshield.cpp

LCDShield::LCDShield()
{

#if defined(__AVR_ATmega2560__) || defined(__AVR_ATmega1280__)
	DDRB = ((1<<DIO)|(1<<SCK));     //Set DIO and SCK pins on PORTB as outputs
	DDRH = ((1<<CS)|(1<<LCD_RES));  //Set CS and RES pins PORTH as outputs
#else
	DDRB = ((1<<CS)|(1<<DIO)|(1<<SCK)|(1<<LCD_RES));  //Set the control pins as outputs
#endif

	DDRD	=	0x00;
	PORTD	=	0xFF;
}

Those DDRD ddrb DDRH and PORTD are atmel specific registers. Those need to be checked and ported to the MCHP equivalent registers.

I tried changing the data inside, but i'm still unable to project the image and i'm stuck for quite some time.

I would try to port it for you but I dont have the shield.

There is a shield I have that did work for me from nkc electronics. http://store.nkcelectronics.com/rgb-lcd-shield-for-arduino-65k-color-k65.html

Here is the lib for it http://www.henningkarlsen.com/electronics/library.php?id=8 And another option for a lib http://iteadstudio.com/notification/utft-library-compatible-with-most-of-itdb02-series-lcd/

I know it isn't what you were hoping for but this one works already (and is half the price) I was going to try picking up the shield to help you out but 40$ is beyond what I can do now. I just figured I would show you another option in case you just want to get working with something already ported.
