Detailed Description

The interface for led matrix and eventual other led screens.

This class abstracts the interface to a led screens. You cannot define this class as an object. This class should be derieved by any class that implements a led screen.

Constructor & Destructor Documentation

Screen::Screen ( int  w, int  h  )

inline

Specify the width and height of the screen.

Width and height are in pixel.

Member Function Documentation

virtual void Screen::drawPixel ( int  , int  , uint8_t  , uint8_t  , uint8_t    )

pure virtual

Draw a given pixel with a color R G B.

the first int argument is the width position and the second is the height position of a pixel. rgb color is between 0 and 255.

Implemented in matrix.

virtual void Screen::drawPixel ( int  , int  , uint32_t    )

pure virtual

Draw a pixel with a hexadecimale color.

the first int argument is the width position and the second is the height position of a pixel. color is rgb is hexa or decimale.

Implemented in matrix.

virtual void Screen::swap_buffer ( bool  copy )

inlinevirtual

Swap the back buffer with front buffer.

You can also copy the values of new buffer to the old buffer by passing a true bool to the function.

Reimplemented in matrix.
