lcd_load( )
Syntax:
Parameters:
Returns:
Function:
Availability:
Requires
lcd_load (buffer_pointer, offset, length);
buffer_pointer points to the user data to send to the LCD, offset is the offset
into the LCD segment memory to write the data, length is the number of bytes
to transfer to the LCD segment memory.
undefined.
This function will load length bytes from buffer_pointer into the LCD segment
memory beginning at offset. The lcd_symbol( ) function provides as easier
way to write data to the segment memory.
Only on devices with built-in LCD Driver Module hardware.
Constants are defined in the devices *.h file.
Examples:
lcd_load(buffer, 0, 16);

lcd_symbol( )
Syntax:
Parameters:
Returns:
Function:
Availability:
Requires
lcd_symbol (symbol, bX_addr);
symbol is a 8 bit or 16 bit constant.
bX_addr is a bit address representing the segment location to be used for bit
X of the specified symbol.
1-16 segments could be specified.
undefined
This function loads the bits for the symbol into the segment data registers for
the LCD with each bit address specified. If bit X in symbol is set, the segment
at bX_addr is set, otherwise it is cleared. The bX_addr is a bit address into the
LCD RAM.
Only on devices with built-in LCD Driver Module hardware.
Constants are defined in the devices *.h file.
