(Universal) Color LCD graphics library

[RobG 1,892]

Updated 2 files: colorLCD.c and font_11x16.h

What's new? Small speed improvements and font background.

In most cases, fonts with background should be faster, but if you have a lot of white spaces, you could try using old functions (they are commented out.)

The main advantage of using new functions is that you don't have to erase before writing new content and updates are faster and flicker free.

Do you feel like this library is slow? Well, I have a good news for you

I have few updates coming and one of them is hardware SPI option (available only for 1.8" JD-T1800 and 2.2" LCD with touch displays, no Nokia.)

With this new option, you will get about 500% speed increase, take a look:

 

Drawing 600 shapes and about 3000 different size characters.

Holy crap!

[RobG 1,892]

Exactly.

I was working on some GUI controls for my touch LCD and really needed that boost.

The only possible problem is the touch controller chip which has 2MHz max clock speed.

 

BTW, I get about 5fps on 2.2" display and about 10fps on 1.8" (fill the entire screen with color, 176 x 220 & 128 x 160.)

Rob,

 

Great work on the library, it works great! I need a larger font, did you use a program to generate the fonts or do it by hand.  I have looked at several of the programs that are available but the ones I have found have variaable character widths.

 

Thanks

Hey RobG, nice work on the libraries as always! Had a question for ya..

Is there any easy way to rotate the ILI9225B display so the libraries work horizontally? I was able to get text to display horizontally but that required modding of control registries as well as the font functions.

[RobG 1,892]

I had a hard time getting horizontal to work. HX and ST driver works like a charm with updates to just 3 lines of code, but ILI is not.

I will take a look again tonight.

[RobG 1,892]

Here are the changes required to make ILI9225B horizontal. In the next round of updates, I will add conditionals to make H/V switch possible with a single define.

 

colorLCD.h

#ifdef ILI9225B
//
#define USE16BIT
#define LCD_HEIGHT 176 // horizontal
#define LCD_WIDTH 220 // horizontal

colorLCD.c

 

#ifdef ILI9225B

	char trueXStart, trueYStart, trueXEnd, trueYEnd; // horizontal
	trueXStart = yStart; // horizontal
	trueXEnd = yEnd; // horizontal
	trueYStart = xStart; // horizontal
	trueYEnd = xEnd; // horizontal

	writeCommand(ILIGRAMHEA);
	writeData(0);
	writeData(trueXEnd + LCD_OFFSET_WIDTH); // horizontal
	writeCommand(ILIGRAMHSA);
	writeData(0);
	writeData(trueXStart + LCD_OFFSET_WIDTH); // horizontal

	writeCommand(ILIGRAMVEA);
	writeData(0);
	writeData(trueYEnd + LCD_OFFSET_HEIGHT); // horizontal
	writeCommand(ILIGRAMVSA);
	writeData(0);
	writeData(trueYStart + LCD_OFFSET_HEIGHT); // horizontal

	writeCommand(ILIGRAMADDRX);
	writeData(0);
	writeData(trueXStart + LCD_OFFSET_WIDTH); // horizontal
	writeCommand(ILIGRAMADDRY);
	writeData(0);
	writeData(trueYStart + LCD_OFFSET_HEIGHT); // horizontal

void initILI9225B() {

	writeCommand(0x28);
	delay(20);
	writeCommand(0x01);
	writeData(0x03); // set SS and NL bit // horizontal
	writeData(0x1C);
	writeCommand(0x02);
	writeData(0x01); // set 1 line inversion
	writeData(0x00);
	writeCommand(0x03);
	writeData(0x10); // set GRAM write direction and BGR=1.//1030
	writeData(0x38); // horizontal

Very nice work RobG, congrats.

 

I have test in a StellarisLaunchpad with a Nokia 2760 lcd and works great.

Have you put the source with SPI Hardware in any place,  i like to study.

Can you free the UARTS pins in next developments, i cant enable uart to work.

Regards.

Can you post your latest code?

[RobG 1,892]

I will this weekend, I have to clean it up.

[RFDesign 0]

Hi,

nice library. I got some 2.4" TFTs having also a SD card holder using a SSD1289 controller.

Can you possibly add support for this controller ?

 

Regards

Peter

Noob problems:

Purchased latest offering of the 2.2" LCD (beautiful work!!!), soldered on the connectors, plugged in and it lights up. Yippee!  Then comes using it.  Create a new project in CCS for the Lights Out game.  Downloaded all of RobG's latest files in Post #20, searched and found a copy of the msp430g2553.h file on internet.  Placed this and the color.h and colorLCD.h files, plus the in430.h file in the same Project folder, clearing the question marks (?) next to the INCLUDE statements at the start of main.c.

But now I get a wad of nasty errors.  Noob can't figure out what he's done wrong.  Any help appreciated.

msp430g2553.h should be available in CCS so the line below is all you need, delete msp430g2553.h file from your project.

include "msp430g2553.h"

 

You are also missing typedefs.h from post #20.

[EdZackRee 0]

RobG - thanks!  Sorry I couldn't reply sooner.  I will search harder, but I didn't find msp430g2553.h the last time I looked through the CCS files.  Probably an operator error.

 

Thanks again.
