Re: [oopic] Re: oopic oSPIL and a 74165 - I Got It To WORK!

Richard YOU ARE A GENIUS!  I added the full complement of signals for the oSPIL and THAT did the trick!  I also dropped the ClkInhibit line and tied that off to Ground. Now when I switch my data lines around I get a different reading (correct) every time. Thanks so much for hangin' in with me even when I gave up! I've gotta scrounge a 'scope from somewhere. WHOO_HOO I can move on. Thanks again man.

I didn't have a '165 so I built one from a CPLD and a little VHDL
code based on the logic diagram from TI. It works...

The thing is, you have to define IOLines for all of the oSPIL signals
whether you use them or not. In other words, you need to add in setup
():

C165.IOLineO = 11
C165.IOLineE = 12

I added a serial port to the code so I could see the result:

Dim C165 As oSPIL
Dim Load As oDIO1
Dim Info As oByte
Dim Serial As New oSerialPort

Sub main()
ooPIC.Delay = 5000
Call setup
Serial.String = "Hello"

Do
Load.Value = 0
Load.Value = 1

Info.Data = C165.Value
Serial.String = Str$(Info.Data)
Serial = 13
Serial = 10

Loop

End Sub

Sub setup()

C165.IOLineC = 9
C165.IOLineI = 10
C165.IOLineO = 11
C165.IOLineE = 12
C165.Rate = 0
C165.Width = cv8Bit
C165.Mode = 0
C165.Operate = cvOn

Load.IOLine = 14
Load.Direction = cvOutput
Load.Value = 1

Serial.Baud = cv9600
Serial.Operate = cvTrue

End Sub

I couldn't get the Comm window in V6 to work reliably. Then again,
Hyperterminal doesn't always connect either. I looked at the serial
transmit pin to verify I was sending stuff and them kept kicking at
Hyperterminal until it worked. What a piece of crap!

So, lesson learned: just because the 'scope makes it look like the
object is working doesn't mean it actually receives anything.
Sometimes you just have to connect to real hardware.

Lesson reinforced: CPLDs are a lot of fun.
