procedure SPI_Glcd_V_Line(y_start: byte; y_end: byte; x_pos:
byte; color: 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);

procedure SPI_Glcd_V_Line(x_start : byte; x_end : byte; y_pos :
yte; color : 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)

SPI_Glcd_H_Line(10, 50, 20, 1);
