procedure Glcd_Circle(x_center: integer; y_center: integer;
radius: integer; color: 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, see Glcd_Init routine.

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

Glcd_Circle(50, 50, 10, 1);

procedure Glcd_Set_Font(const ActiveFont: ^byte; FontWidth: byte;
FontHeight: byte; FontOffs: word);

Nothing.

Sets font that will be used with Glcd_Write_Char and Glcd_Write_Text routines.

Parameters : 

- activeFont: font to be set. Needs to be formatted as an array of byte 
- aFontWidth: width of the font characters in dots. 
- aFontHeight: height of the font characters in dots. 
- aFontOffs: number that represents difference between the mikroPascal PRO 

for AVR character set and regular ASCII set (eg. if 'A' is 65 in ASCII character, 
and 'A' is 45 in the mikroPascal PRO for AVR character set, aFontOffs is 20). 
Demo fonts supplied with the library have an offset of 32, which means that 
they start with space. 

The user can use fonts given in the file “__Lib_GLCDFonts.mpas” file located in
the Uses folder or create his own fonts.

Glcd needs to be initialized, see Glcd_Init routine.

' Use the custom 5x7 font "myfont" which starts with space (32):

Glcd_Set_Font(myfont, 5, 7, 32);
