Detailed Description

Functionality to draw simple geometric objects on the lcd.

Function Documentation

void LCD_DrawCircle	(	uint16_t	Xpos,
		uint16_t	Ypos,
		uint16_t	Radius,
		LCDCOLOR	Color
	)

Displays a circle.

Parameters

[in]	Xpos	specifies the X position of the center.
[in]	Ypos	specifies the Y position of the center.
[in]	Radius	radius of the circle.
[in]	Color	specifies the color of the line.

void LCD_DrawCircleF	(	uint8_t	Xpos,
		uint16_t	Ypos,
		uint16_t	Radius,
		LCDCOLOR	Color
	)

Displays a filled circle.

Parameters

[in]	Xpos	specifies the X position of the center.
[in]	Ypos	specifies the Y position of the center.
[in]	Radius	radius of the circle.
[in]	Color	specifies the color of the line.

		uint16_t	Ystart,
		uint16_t	Xstop,
		uint16_t	Ystop,
		LCDCOLOR	Color
	)

Draw a line on the display starting at (Xstart/Ystart) and ending at (Xstop/Ystop). This function draws the line with the Bresenham's line algorithm.

Parameters

[in]	Xstart	specifies the X start position.
[in]	Ystart	specifies the Y start position.
[in]	Xstop	specifies the X stop position.
[in]	Ystop	specifies the Y stop position.
[in]	Color	specifies the color of the line.

void LCD_DrawRect	(	uint16_t	Xpos,
		uint16_t	Ypos,
		uint16_t	width,
		uint16_t	height,
		LCDCOLOR	Color
	)

Displays a rectangle.

Parameters

[in]	Xpos	specifies the X position.
[in]	Ypos	specifies the Y position.
[in]	width	display rectangle width.
[in]	height	display rectangle height.
[in]	Color	specifies the color of the line.
