sub procedure Glcd_Dot(dim x_pos as byte, dim y_pos as byte, dim
color as byte)

Nothing.

Draws a dot on Glcd at coordinates (

x_pos

, 

y_pos

). 

Parameters : 

- 

x_pos:

x position. Valid values: 0..127 

- 

y_pos:

y position. Valid values: 0..63 

- 

color:

color parameter. Valid values: 0..2 

The parameter 

color

determines a dot state: 0 clears dot, 1 puts a dot, and 2

inverts dot state.

Note: For x and y axis layout explanation see schematic at the bottom of this page.

Glcd needs to be initialized, see Glcd_Init routine.

' Invert the dot in the upper left corner
Glcd_Dot(0, 0, 2)

sub procedure Glcd_Line(dim x_start as integer, dim y_start as inte-
ger, dim x_end as integer, dim y_end as integer, dim color as byte)

Nothing.

Draws a line on Glcd.

Parameters : 

- 

x_start:

x coordinate of the line start. Valid values: 0..127 

- 

y_start:

y coordinate of the line start. Valid values: 0..63 

- 

x_end:

x coordinate of the line end. Valid values: 0..127 

- 

y_end:

y coordinate of the line end. Valid values: 0..63 

- 

color:

color parameter. Valid values: 0..2 

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

Glcd needs to be initialized, see Glcd_Init routine.

' Draw a line between dots (0,0) and (20,30)
