[time-nuts] linux-gpib working on a RasPI

[cfo]

I have finally succeded in making linux-gpib build and 
load the agilent_82357a_gpib module.

Now i have a 3..5 Watt- "Networked GPIB-Adapter" , where even python 
bindings work.

pi at raspberrypi-3 ~/raspi $ sudo python
Python 2.7.3 (default, Jan 13 2013, 11:20:46) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Gpib
>>> inst = Gpib.Gpib(0,16) # address 6
>>> inst.write("*IDN?")
>>> inst.read(100) # read 100 bytes
'KEITHLEY INSTRUMENTS INC.,MODEL 2015,1043877,B15  /A02  \n'
>>> 


I have tested (just *IDN? for now) with an Agilent 82357B and a Beiming 
S82357 GPIB-USB. Both reported my Keithley IDN ok.
