HEX Help 1

[WildGun]

Hi

I receive a HEX string using the MSComm RS-232 port interface, it is received in the following way "01 D0 05 07" most of the binary bit are useful and I understand how to break it down. The HEX string is retransmitted every 500ms with new data but always in the same format.
"01 D0 05 07"
"02 D2 05 05"
"03 A0 05 03"
I only need to deal with one string at a time so out with the old and in with the new. My question is how should I configure MSComm to collect the HEX and is there an easy way to convert it to Binary?

Thanks

Randy

Look in VBHelp for the MSComm control properties InputLen and InputMode.

To convert a Long to Binary I use a std function

'---------------------------------------------------------------------------------------
' Procedure : fncBinary
' DateTime  : 15/06/2001 08:33
' (C)       : John M
' Purpose   : Generates Binary string
' Takes     : Long to convert
' Returns   : Binary string
'---------------------------------------------------------------------------------------
'
Public Function fncBinary(inpLong As Long) As String
Dim Remainder As Long
Remainder = inpLong
Do While Remainder > 0
fncBinary = Remainder Mod 2 & fncBinary
Remainder = Remainder \ 2
Loop
End Function

To get the numeric value of a Hex string just evaluate the string with &H in front. If myHstring contains FF then

myValue = "&H" & myHstring

will give 255
