Python VISA for Windows 7 64 bit

Dan D — Fri, 07 Jun 2013 16:22:41 -0000

Hi,

The reviews for Python VISA are very good, and I am trying to get it to work on my Windows 7 64-bit machine. Could you give any advice on how to make this happen.

Thanks a lot!
Dan

#6 Give some love to Windows 7 x64 installation

Hi,

I have read the great reviews of PyVISA, and I am also trying to get it to work on my Windows7 64-bit machine. Do you have any recommendations on how to get PyVISA working on this operating system?

Thanks,
Dan

Give some love to Windows 7 x64 installation

This is a great package.

It would be great if the binary installer for Windows:
- Ran correctly under Windows 7 x64 without hacks
- Had a silent switch

Even nicer would be if it installed correctly from the Python Package Index (using easy_install, pip etc) under Windows.

Thanks!

add int32 support for binary transfer

benhoo — Fri, 03 Aug 2012 20:57:20 -0000

I would really like to do basic binary transfers with simple int32 returning. If you have a good way of getting a binary representation of a single in python that would probably be fine, too.

VI_ATTR_ASRL_END_OUT

Larry C — Tue, 31 Jan 2012 00:56:07 -0000

Have you had any requests for interface methods to VI_ATTR_ASRL_END_OUT ?
self.serial_end_out = keyw.get("serial_end_out", serial_end_output)
__get_end_output()
__set_end_output() indicates the method used to terminate read operations

I wanted to read the current value and didn't see a direct method for accomplishing that.
I hacked in my own patch in SerialInstrument() and it worked; but I'm curious about what other folks think of this idea.
Thanks; Larry

Mac version

This looks like exactly what I am looking for. Why is it not implemented on macs?
Thanks!

Support for binary block formats

Satya N Mishra — Fri, 08 Feb 2008 23:09:07 -0000

Looks like the standard for a binary block is

#<byte0><byte1>...<byteN><data0>...<dataM>

where # is the character '#'
N = int(<byte0>)
M = int(<byte1>...<byteN>)
and <data0>...<dataM> is the actual binary data. One would of course have to know the data type of the binary to decode it. The following python code illustrates it for 32-bit floating point data

if data[0] == '#':
n_len_bytes = int(data[1])
npoints = int(data[2:2 + n_len_bytes])/4
return struct.unpack('>%df' % npoints, data[2 + n_len_bytes:])
else:
return []

TCPIP connection support

Are there any plans to extend control over network connections, or can that be done already through NIvisa calls?
