Hi,

Really nice work you guys. Its a very useful library.
Is there a way to invert the colors of display (black font with blue or green background) ?

Thanking in advance

Yes, you need to add the bits in red,

Code:

void GLCD_Write_Data (unsigned char data){
	Wait_Not_Busy();
	GLCD_Data = data^0xff;
	b_GLCD_RS=1;
	b_GLCD_RW=0;
	b_GLCD_E=1;
	Delay();
	b_GLCD_E=0;
}

unsigned char GLCD_Read_Data(void){
	Wait_Not_Busy();
	TRIS_Data=0xff;
	b_GLCD_RS=1;
	b_GLCD_RW=1;
	b_GLCD_E=1;
	Delay();
	W=GLCD_Data^0xff;
	b_GLCD_E=0;
	TRIS_Data=0x00;
	return W;
}

Thank you Pommie for the quick reply, it has inverted the Data but now there is a new problem.

The backgound is still black and the text is inverter (Black font with blue background) what i wanted. However i actually wanted to make the complete background blue and only font black..

The attached image will help you understand what i meant.

The text is displaying okay but the background is annoying now

I have solved this issue but the method is really stupid so i was looking for a more professional solution for it

Pommie · Yesterday, 07:52 AM

You must have changed some other part of the code as it works perfectly on mine. What happens if you call ClearScreen before printing the text?

Mike.

AtomSoft · Yesterday, 12:06 PM

what is your current code for:

Code:

void ClearScreen(void)

also pommie shouldnt this be more like:

Code:

void GLCD_Write_Data (unsigned char data){
	Wait_Not_Busy();
	GLCD_Data = ~(data);
	b_GLCD_RS=1;
	b_GLCD_RW=0;
	b_GLCD_E=1;
	Delay();
	b_GLCD_E=0;
}

unsigned char GLCD_Read_Data(void){
	Wait_Not_Busy();
	TRIS_Data=0xff;
	b_GLCD_RS=1;
	b_GLCD_RW=1;
	b_GLCD_E=1;
	Delay();
	W=~(GLCD_Data);
	b_GLCD_E=0;
	TRIS_Data=0x00;
	return W;
}

Pommie it gives the same result.

ClearScreen when called actually turns the screen complete black. Is it possible that my screen is running in inverted mode already. When (in proteus) the screen is powered on, it gives black background.

AtomSoft: Its the same thing, gives the same result

I tried what you said earlier before asking question here on forum

AtomSoft · Yesterday, 01:52 PM

Is this your GLCD clear screen?

Code:

void ClearScreen(void){
unsigned char i,j;
	b_GLCD_GCS1=1;
	b_GLCD_GCS2=1;	
	for(i=0;i<8;i++){
		GLCD_Write_Cmd(0x40);	//y=0
		GLCD_Write_Cmd(0xb8+i);	//x=0
		for(j=0;j<0x40;j++)
			GLCD_Write_Data(0x00);
	}
	SetPos(0,0);
}

AtomSoft · Yesterday, 01:54 PM

heh for some reason not working now

haxan · Yesterday, 02:13 PM

AtomSoft: It doesnt actually make any difference.

I have tried

GLCD_Write_Data(0x00);
and
GLCD_Write_Data(~(0x00));
and
GLCD_Write_Data(0xFF);

Still gives the same result

AtomSoft · Yesterday, 02:46 PM

heh please tell me you are trying this in proteus

AtomSoft · Yesterday, 02:49 PM

If you are then try this:

also revert all the data back to normal, meaning If you changed the read data and others put them back to normal.... the only thing that should be changed is:

Code:

void GLCD_Write_Data (unsigned char data){
	Wait_Not_Busy();
	GLCD_Data =~data;
	b_GLCD_RS=1;
	b_GLCD_RW=0;
	b_GLCD_E=1;
	Delay();
	b_GLCD_E=0;
}

haxan · Yesterday, 04:02 PM

Thank you so much

It finally works by changing the initial contents of Ram.

Will this work in real GLCD project aswell (i hope so)

AtomSoft · Yesterday, 11:13 PM

it should heh.... and your welcome

ill test it out later on or tomorrow and ill take some pictures
