procedure SPI_Glcd_Rectangle(x_upper_left : byte; y_upper_left :
byte; x_bottom_right : byte; y_bottom_right : byte; color : byte);

Nothing.

Draws a rectangle on Glcd.

Parameters : 

- 

x_upper_left

: x coordinate of the upper left rectangle corner. Valid values: 

0..127 

- 

y_upper_left

: y coordinate of the upper left rectangle corner. Valid values: 

0..63 

- 

x_bottom_right

: x coordinate of the lower right rectangle corner. Valid val

ues: 0..127 

- 

y_bottom_right

: y coordinate of the lower right rectangle corner. Valid val

ues: 0..63 

- 

color

: color parameter. Valid values: 0..2 

The parameter color determines the color of the rectangle border: 0 white, 1
black, and 2 inverts each dot.

Glcd needs to be initialized for SPI communication, see SPI_Glcd_Init routines.

// Draw a rectangle between dots (5,5) and (40,40)
SPI_Glcd_Rectangle(5, 5, 40, 40, 1);

procedure SPI_Glcd_Box(x_upper_left : byte; y_upper_left : byte;
x_bottom_right : byte; y_bottom_right : byte; color : byte);

Nothing.

Draws a box on Glcd.

Parameters : 

- 

x_upper_left

: x coordinate of the upper left box corner. Valid values: 0..127 

- 

y_upper_left

: y coordinate of the upper left box corner. Valid values: 0..63 

- 

x_bottom_right

: x coordinate of the lower right box corner. Valid values: 0..127 

- 

y_bottom_right

: y coordinate of the lower right box corner. Valid values: 0..63 

- 

color

: color parameter. Valid values: 0..2 

The parameter color determines the color of the box fill: 0 white, 1 black, and 2
inverts each dot.

Glcd needs to be initialized for SPI communication, see SPI_Glcd_Init routines.

// Draw a box between dots (5,15) and (20,40)

SPI_Glcd_Box(5, 15, 20, 40, 1);
