sub procedure SPI_Glcd_Box(dim x_upper_left as byte, dim
y_upper_left 

as byte, dim x_bottom_right as byte, dim

y_bottom_right 

as byte, dim color as 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)

ter 

as integer, dim radius as integer, dim color as byte)

Nothing.

Draws a circle on Glcd.

Parameters : 

- 

x_center:

x coordinate of the circle center. Valid values: 0..127 

- 

y_center:

y coordinate of the circle center. Valid values: 0..63 

- 

radius:

radius size 

- 

color:

color parameter. Valid values: 0..2 

The parameter 

color

determines the color of the circle line: 0 white, 1 black,

and 2 inverts each dot.

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

' Draw a circle with center in (50,50) and radius=10
