hello all, i've successfully installed and tested linux-gpib on a raspberry pi 4+b with a NI-GPIB-USB-HS dongle and communicating with a Keithley 2000 DMM instrument using python 3. should be fairly common and pervasive i have python sending *idn? and receiving the proper instrument response, "KEITHLEY INSTRUMENT INC., MODEL 2000, ..." etc. so that much is working well. i'd like to setup the dmm to assert and trigger 25 voltage measurement and when complete, signal back to the waiting raspberry that it's completed its 25 measurements, and then the computer can download those 25 measurements and process the voltages accordingly. will anyone share or point to some python code where this works properly under similar circumstances, linux-gpib, GPIB-USB-HS, python, etc.???? especially how to setup the assert, trigger, and raspberry wait steps. thank you for your time and effort. lucas |
