Hi I am a new to frontpanel and python and I am trying to test the pipein and pipout interfaces. I was able to do this with frontpanel but it is limited to pushbutton controlled read an write so I wanted to try python.
I installed python 2.4.1 from the opal kelly cd and I am running on windows 2000 I get the following error
IDLE 1.1.1 ==== No Subprocess ====
------ DES Encrypt/Decrypt Tester in Python ------
Traceback (most recent call last):
File “C:\Python24\OKpy\DESTester.py”, line 116, in ?
if (False == des.InitializeDevice()):
File “C:\Python24\OKpy\DESTester.py”, line 12, in InitializeDevice
if (self.xem.NoError != self.xem.OpenBySerial("")):
File “C:\Python24\lib\site-packages\ok\ok.py”, line 131, in
getattr = lambda self, name: _swig_getattr(self, FrontPanel, name)
File “C:\Python24\lib\site-packages\ok\ok.py”, line 21, in _swig_getattr
I don’t know where to go from here?
I also tried the precompiled c++ program DESTester.exe and it got further but failed configuring the fpga. I did copy the correct bit file to destop.bit

FPGA configuration failed.
FPGA could not be initialized.
I think the problem with the exe is that asyncronous transfers are enabled? I had to disable them in the frontpanel preferences to get it to configure the fpga.
