GCBASIC documentation
Deprecated bitwise functions.

Syntax:

    BitOut = FnNotBit(BitIn)

Command Availability:

Available on all microcontrollers.

Explanation:

FnNotBit is the bitwise equivalent of the logical NOT operator. Where BitOut will be the Logical Compliment of BitIn.

FnNotBit will return the Logic Compliment State of BitIn. It is equivalent to the 'C' statement as shown below.

    BitOut != BitIn

FnNotBit can be used to assign a non bit variable to a bit variable. BitIn may be a variable and of type: Bit, Byte, Constant or another Function. If BitIn is of type Word or Long only the Least Significant 8 bits will be evaluated. It will return 1 if BitIn evaluates to anything other than zero.

Note: If BitOut is an I/O Bit, then SetWith should be used to encapsulate the function. See below.

Example:

    ' This program will flash the LED - DS1(RC0) on the Microchip PIC Low Pin Count Demo Board.

    #chip   16f690    ' declare the target Device

    #Define DS1 PORTC.0

    DIR DS1 Out

    Do
      ' set the Bit DS1 to the Compliment of DS1
      SetWith( DS1, FnNotBIT( DS1 ) )
      wait 500 ms
    Loop

    END
