Type
Function returning Boolean
Invocation
ParityCheck(data, oddParity)
Parameter
Method
Type
Description
data
ByVal
Byte
The data value for which to check the parity.
oddParity
ByVal
Boolean
The desired parity: True -> odd parity, False -> even parity
Discussion
This function computes the parity over the eight bits of the provided data value and compares that result
to the desired result indicated by the oddParity parameter. The return value is a pass/fail indicator
where True means that the parity matched the desired parity.
The data value has even parity if the number of one bits in the value is even.
Example
Dim b as Byte
If Not ParityCheck(b, False) Then
Debug.Print "Even parity check failed"
End If
