Parameters:
state FALSE: switch on, TRUE: switch off

Definition at line 139 of file lcd.c.

void LCD_setBGColor ( uint16_t  bgColor  )  [inline]

Set backround's color. This data is used by LCD_printf() and LCD_write().

Parameters:
bgColor Color of background (12 bit). Example: LCD_COLOR_RED

Definition at line 619 of file lcd.c.

void LCD_setColor ( uint16_t  fgColor,
uint16_t  bgColor 
) [inline]

Set color of foreground and background. This data is used by LCD_printf() and LCD_write().

Parameters:
fgColor Color of foreground (12 bit). Example: LCD_COLOR_WHITE
bgColor Color of background (12 bit). Example: LCD_COLOR_RED

Definition at line 624 of file lcd.c.

void LCD_setContrast ( unsigned char  contrast  ) 

Set display's contrast. Supported only on type GE8!

Parameters:
contrast Valid values: 0..223 (?)

Definition at line 151 of file lcd.c.

void LCD_setFGColor ( uint16_t  fgColor  )  [inline]

Set foreground's color. This data is used by LCD_printf() and LCD_write().

Parameters:
fgColor Color of foreground (12 bit). Example: LCD_COLOR_WHITE

Definition at line 614 of file lcd.c.

void LCD_setX ( uint8_t  x  )  [inline]

Set coordinate X. This data is used by LCD_printf() and LCD_write().

See also:
LCD_WIDTH
Parameters:
x X coordinate. Valid values: 0..LCD_WIDTH.

Definition at line 588 of file lcd.c.

void LCD_setXY ( uint8_t  x,
uint8_t  y 
) [inline]

Set coordinates X and Y. This data is used by LCD_printf() and LCD_write().

See also:
LCD_HEIGHT, LCD_WIDTH
Parameters:
x X coordinate. Valid values: 0..LCD_WIDTH.
y Y coordinate. Valid values: 0..LCD_HEIGHT.

Definition at line 598 of file lcd.c.

void LCD_setY ( uint8_t  y  )  [inline]

Set coordinate Y. This data is used by LCD_printf() and LCD_write().

See also:
LCD_HEIGHT
Parameters:

Definition at line 593 of file lcd.c.

void LCD_write ( const char *  buf,
uint16_t  length 
)

Write a character buffer to LCD.

Author:
Peter Ivanov
Parameters:
buf Pointer to buffer.
length Length of buffer.

Definition at line 641 of file lcd.c.

void LCD_write130x130bmp ( const unsigned char *  bmp  ) 

Displays a bitmap array. Bitmap size is equal to LCD_MEM_SIZE (25740).

Parameters:
bmp Pointer to the bitmap array.

Definition at line 411 of file lcd.c.

void LCD_write130x130bmpData16 ( const uint16_t *  data  ) 

Put one word to the LCD's memory.

See also:
LCD_write130x130bmpStart, LCD_write130x130bmpData8, LCD_write130x130bmpEnd
Parameters:
data One word of bitmap.

Definition at line 390 of file lcd.c.

void LCD_write130x130bmpData8 ( const uint8_t *  data  ) 

Put one byte to the LCD's memory.

See also:
LCD_write130x130bmpStart, LCD_write130x130bmpData16, LCD_write130x130bmpEnd
Parameters:
data One byte of bitmap.

Definition at line 396 of file lcd.c.

void LCD_write130x130bmpEnd (  ) 

Switches on the display, so the bitmap will be visible.

See also:
LCD_write130x130bmpStart, LCD_write130x130bmpData8, LCD_write130x130bmpData16

Definition at line 400 of file lcd.c.

void LCD_write130x130bmpStart (  ) 

Initializes LCD to show a bitmap. You should put the data byte by byte or word by word to the memory using LCD_write130x130bmpData16() or LCD_write130x130bmpData8(). After that you should call LCD_write130x130bmpEnd(). Bitmap size is equal to LCD_MEM_SIZE (25740).

See also:
LCD_write130x130bmpData16, LCD_write130x130bmpData8, LCD_write130x130bmpEnd, LCD_MEM_SIZE

Definition at line 370 of file lcd.c.

void LCD_writeBall ( unsigned char  x,
unsigned char  y 
)

Draws ball symbol.

Parameters:
x Coordinate X.
y Coordinate Y.

Definition at line 499 of file lcd.c.

void LCD_writeChar ( unsigned char  Ascii,
unsigned char  x,
unsigned char  y,
unsigned short  FG_Colour,
unsigned short  BG_Colour 
)

Write a character to specified position with specified color. LCD_printf() is a bit more user friendly.

See also:
LCD_printf()
