Function CRC_CCITT(data() As Byte) As String
      Dim CRC16Lo As Byte, CRC16Hi As Byte
      Dim CL As Byte, CH As Byte
      Dim SaveHi As Byte, SaveLo As Byte
      Dim i As Integer
      Dim Flag As Integer
      CRC16Lo = &HFF
      CRC16Hi = &HFF
      CL = &H21
      CH = &H10
      For i = 0 To UBound(data)
        CRC16Hi = CRC16Hi Xor data(i)
        For Flag = 0 To 7
          SaveHi = CRC16Hi
          SaveLo = CRC16Lo
          If CRC16Hi * 2 > &HFF Then
            CRC16Hi = CRC16Hi * 2 - &H100
          Else
            CRC16Hi = CRC16Hi * 2
          End If
          If CRC16Lo * 2 > &HFF Then
            CRC16Lo = CRC16Lo * 2 - &H100
          Else
            CRC16Lo = CRC16Lo * 2
          End If
          If ((SaveLo And &H80) = &H80) Then
            CRC16Hi = CRC16Hi Or &H1
          End If
          If ((SaveHi And &H80) = &H80) Then
            CRC16Hi = CRC16Hi Xor CH
            CRC16Lo = CRC16Lo Xor CL
          End If
        Next Flag
      Next i
      Dim ReturnData(1) As Byte
      ReturnData(0) = CRC16Hi
      TextBox1.Text = TextBox1.Text & vbCrLf & CStr(CRC16Hi)
      ReturnData(1) = CRC16Lo
      TextBox1.Text = TextBox1.Text & vbCrLf & CStr(CRC16Lo)
      CRC_CCITT = ReturnData
    End Function

加速器，网上很多源码，百度一下。
