Target Description

Actually it is not possible to use the system without terminal access (UART or Telnet). It has to be possible to use the system at least at the basic level, also without access to a PC.

Interface

Drawer interface

// draws program icon
extern void cgraphic_DrawProgramIcon( oC_Program_t Program, const oC_Pixel_Position_t Position );
//  draws file icon
extern void cgraphic_DrawFileIcon( const char * Path, const oC_Pixel_Position_t Position );
// draws time box
extern void cgraphic_DrawTimeBox( const oC_Pixel_Position_t * Position );
// draws CPU load box
extern void cgraphic_DrawCPULoadBox( const oC_Pixel_Position_t * Position );
// draws box with text
extern void cgraphic_DrawButton( const oC_Pixel_Position_t * Position , const char * String );
// draws progress bar
extern void cgraphic_DrawProgressBar( const oC_Pixel_Position_t * Position, uint32_t Value, uint32_t Max );
// draws system logo
extern void cgraphic_DrawSystemLogo( const oC_Pixel_Position_t * Position, oC_Pixel_ResolutionUInt_t Width, oC_Pixel_ResolutionUInt_t Height );

Status bar interface

// draws status bar
extern void cgraphic_DrawStatusBar( void );

File manager

// Draws files from the given page
extern void cgraphic_DrawFilesFromPage( int PageIndex );

General Description

The program is responsible for providing graphic interface for user, that allows for basic managing of the system, running programs and manage files.
