how do you call it? Whats top, left, x,y ?

x0 = ?
x1 = ?

y0 = ?
y1 = ?

now, I have added the circle function: lcd_setcircle().

Code:
/**********************************************************
           draw a circle between two points
					 code shamelessly stolen from Jim Lynch's 6100 driver
					 which itself is based on Jack Bresenham's line algorithm
**********************************************************/
void lcd_setcircle(char x0, char y0, char radius) {

	int f = 1 - radius;
	int ddF_x = 0;
	int ddF_y = -2 * radius;
	int x = 0;
	int y = radius;

	lcd_setpixel(x0, y0 + radius);
	lcd_setpixel(x0, y0 - radius);
	lcd_setpixel(x0 + radius, y0);
	lcd_setpixel(x0 - radius, y0);
	while(x < y) {
		if(f >= 0) {
			y--;
			ddF_y += 2;
			f += ddF_y;
		}
		x++;
		ddF_x += 2;
		f += ddF_x + 1;
		lcd_setpixel(x0 + x, y0 + y);
		lcd_setpixel(x0 - x, y0 + y);
		lcd_setpixel(x0 + x, y0 - y);
		lcd_setpixel(x0 - x, y0 - y);
		lcd_setpixel(x0 + y, y0 + x);
		lcd_setpixel(x0 - y, y0 + x);
		lcd_setpixel(x0 + y, y0 - x);
		lcd_setpixel(x0 - y, y0 - x);
	}
}

the upper left is (0,0), the lower right is (64, 132).

however, the first and the last 18 columns in the Nokia screen don't show. so you will have to remember that.

I did it that way so the program can be easily ported to other true SED1565 displays.

lol i meant the calling it:
Does:

x0= top
x1= left
y0= right
y1= bottom

? how do you figure it out?

it would be quite nice to develop a structure type like that. not terribly important but nice. in my last iteration, I added another parameter to decide on if I want to set or clear the line / circle / rect / ..., rather than using a set() and then a clr().

heh i like the normal names because i might be smart sometimes but im dumb the rest and tend to forget a lot of things. This just helps... hence why i changed again to

Top0, Left0
Top1, Left1

why not just +18 like:

Code:
void lcd_setline(char top0, char left0, char top1, char left1) {

	int dy;
	int dx;
	int stepx, stepy;

   	left0 = left0 + 18;
	left1 = left1 + 18;

	dy = left1 - left0;
	dx = top1 - top0;

	if (dy < 0) { dy = -dy; stepy = -1; } else { stepy = 1; }
	if (dx < 0) { dx = -dx; stepx = -1; } else { stepx = 1; }
	dy <<= 1; // dy is now 2*dy
	dx <<= 1; // dx is now 2*dx
	lcd_setpixel(top0, left0);
	
	if (dx > dy) {
		int fraction = dy - (dx >> 1); // same as 2*dy - dx
		while (top0 != top1) {
			if (fraction >= 0) {
				left0 += stepy;
				fraction -= dx; // same as fraction -= 2*dx
			}
			top0 += stepx;
			fraction += dy; // same as fraction -= 2*dy
			lcd_setpixel(top0, left0);
		}
	} else {
		int fraction = dx - (dy >> 1);
		while (left0 != left1) {
			if (fraction >= 0) {
				top0 += stepx;
				fraction -= dy;
			}
			left0 += stepy;
			fraction += dx;
			lcd_setpixel(top0, left0);
		}
	}
}

Now you can:

Code:
		lcd_setline(0,95,64,95);
		lcd_setline(64,0,64,95);
		lcd_setline(0,0,64,0);
		lcd_setline(0,0,0,95);
to get:

I am going to edit some of the code with the +18 because its a few functions with that issue.

More coding would give you:


Code:
Code:
		lcd_setline(0,95,64,95);
		lcd_setline(64,0,64,95);
		lcd_setline(0,0,64,0);
		lcd_setline(0,0,0,95);

		lcd_setline(52,0,52,95);

		lcd_setline(52,40,64,40);
		lcd_setline(52,54,64,54);

		lcd_str(55,7,"Menu1",NORMAL);
		lcd_str(55,60,"Menu2",NORMAL);
		lcd_str(55,46,"k",NORMAL);

		lcd_setcircle(58,47,5);
using this altered code:

I didnt touch lcd_chr just incase it gets called somewhere else in the future

Jason: that will work. you can also use the lcd_setrect() function to draw a box.

I didn't +18 so the same code can be ported to true sed1565-based displays.

oh ok i see now... lol

you can simply add :

	left += 18;
#endif
remember to

#define NOKIA7110

This is what happens when you dont define the NOKIA7110...


and when you do:


EDIT

what setrect?
I didnt get that code

sorry, I may have added it after I posted it.

here is the latest. I just started but haven't finished yet the bmp function, lcd_setbmp(), so as is the program doesn't compile.

it would be easier and more flexible to just drop the bmp, but it will take up tons of memory - a trade-off.
