ps3000a.dll with python
ps3000a.dll with python
Hi,
I have been using a picoscope 2203 and the ps2000.dll with python and this works well but I have recently purchased a picoscope 3205a and the ps3000a.dll will not open in python. I have both dll's in the same folder and in python get this:
>>> import ctypes as c
>>> p = c.windll.LoadLibrary("ps2000.dll")
>>> p3 = c.windll.LoadLibrary("ps3000a.dll")
Traceback (most recent call last):
File "", line 1, in
p3 = c.windll.LoadLibrary("ps3000a.dll")
File "C:\Python32\lib\ctypes\__init__.py", line 431, in LoadLibrary
return self._dlltype(name)
File "C:\Python32\lib\ctypes\__init__.py", line 353, in __init__
self._handle = _dlopen(self._name, mode)
WindowsError: [Error 127] The specified procedure could not be found
Any help would be very much appreciated.

Re: ps3000a.dll with python
I have an update on this, i reverted to the ps3000a.dll on the CD provided with the scope and all works fine, this dll is part of SDK:
PS3000Asdk_r10_5_0_11
Whereas the dll that would not load was one that I downloaded as the newest version and part of SDK:
PS3000asdk_r10_5_0_32
Regard
PS3000Asdk_r10_5_0_11

Further update!
It looks like the dependencies required for the most up to data dll are in the most up to date Picoscope 6,so this issue is mute. In summary I was using an older version of Picoscope 6 with a newer version of the ps3000a.dll and this caused a problem with the dependencies, this was solved by using the most up to date versions of each.
