sub procedure SPI_Glcd_V_Line(dim y_start as byte, dim y_end as
byte, dim x_pos as byte, dim color as byte)

Nothing.

Draws a vertical line on Glcd.

Parameters : 

- 

y_start:

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

- 

y_end:

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

- 

x_pos:

x coordinate of vertical line. Valid values: 0..127 

- 

color:

color parameter. Valid values: 0..2 

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

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

' Draw a vertical line between dots (10,5) and (10,25)

SPI_Glcd_V_Line(5, 25, 10, 1)

sub procedure SPI_Glcd_V_Line(dim x_start as byte, dim x_end as
byte, dim y_pos as byte, dim color as byte)

Nothing.

Draws a horizontal line on Glcd.

Parameters : 

- 

x_start:

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

- 

x_end:

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

- 

y_pos:

y coordinate of horizontal line. 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 for SPI communication, see SPI_Glcd_Init routines.

' Draw a horizontal line between dots (10,20) and (50,20)
