SHOWPIC

Action

Shows a BGF file on the graphic display

Syntax

SHOWPIC x, y , label

Remarks

Showpic can display a converted BMP file. The BMP must be converted into a BGF file with the Tools Graphic Converter.

The X and Y parameters specify where the picture must be displayed. X and Y must be 0 or a multiple of 8. The picture height and width must also be a multiple of 8.

The label tells the compiler where the graphic data is located. It points to a label where you put the graphic data with the $BGF directive.

You can store multiple pictures when you use multiple labels and $BGF directives,

Note that the BGF files are RLE encoded to save code space.

SHOWPICE

Action

Shows a BGF file stored in EEPROM on the graphic display

Syntax

SHOWPICE x, y , label

Remarks

Showpice can display a converted BMP file that is stored in the EEPROM of the micro processor. The BMP must be converted into a BGF file with the Tools Graphic Converter.

The X and Y parameters specify where the picture must be displayed. X and Y must be 0 or a multiple of 8. The picture height and width must also be a multiple of 8.

The label tells the compiler where the graphic data is located. It points to a label where you put the graphic data with the $BGF directive.

You can store multiple pictures when you use multiple labels and $BGF directives,

Note that the BGF files are RLE encoded to save code space.

SIN

Action

Returns the sine of a float

Syntax

var = SIN( source )

Remarks

Var	A numeric variable that is assigned with sinus of variable source.
source	The single or double variable to get the sinus of.

All trig functions work with radians. Use deg2rad and rad2deg to convert between radians and angles.

SINH

Action

Returns the sinus hyperbole of a float

Syntax

var = SINH( source )

Remarks

Var	A numeric variable that is assigned with sinus hyperbole of variable
	source.
source	The single or double variable to get the sinus hyperbole of.

All trig functions work with radians. Use deg2rad and rad2deg to convert between radians and angles.
