GetBit

Syntax

Assignment Variable = GetBit Variable, Index

Overview

Examine a bit of a variable, or register.

Parameters

Index is a constant, variable, or expression that points to the bit within Variable that requires examining. Assignment Variable is a user defined variable.

Example

' Examine and display each bit of variable MyByte
  Device = 24FJ64GA002             ' Select the device to compile for
  Declare Xtal = 16
  Declare Hserial_Baud = 9600       ' USART1 Baud rate
  Declare Hrsout1_Pin = PORTB.14    ' Select the pin for TX with USART1

  Dim MyByte as Byte
  Dim Index as Byte
  Dim Var1 as Byte

  RPOR7 = 3                           ' Make PPS Pin RP14 U1TX

  MyByte = %10110111
  While                              ' Create an infinite loop
     HrsoutLn Bin8 MyByte             ' Display the original variable
     For Index = 7 to 0 Step -1        ' Create a loop for 8 bits
       Var1 = GetBit MyByte, Index    ' Examine each bit of MyByte
       Hrsout Dec1 Var1               ' Display the binary result
       DelayMs 100                    ' Slow things down to see what's happening
     Next                              ' Close the loop
     Hrsout 13
  Wend                                ' Do it forever
