Useful commands for direct connection to SCPI from the terminal

[redpitaya]

Here is a cheatsheet in the case you find it useful to make a direct connection to SCPI from the terminal first:

$ telnet rp-xxxxxx.local 5000 #mac or linux, or
similar in windows using https://the.earth.li/~sgtatham/putty/la ... /putty.exe
or https://chrome.google.com/webstore/deta ... dbbeonoojo
Or netcat
$ nc -C rp-xxxxxx.local 5000 #mac or linux or
of similar in windows using https://nmap.org/ncat/

for Bash: [or any language with a system() call]
$ echo dig:pin led6,1 | nc -C -q 0 10.0.0.5 5000 #turn on led
$ echo dig:pin? led6 | nc -C -q 0 10.0.0.5 5000 #query led
$ function rp() { echo $* | nc -C -q 0 10.0.0.5 5000; } #to save a few keystrokes
$ while true; do rp dig:pin led2,1; sleep 1; rp dig:pin led2,0; sleep 1; done #blink
$ nc -C 10.0.0.5 5000 # or: telnet 10.0.0.5 5000
> type your commands and see the response in real time


Here's the socket communication functions for Mathematica 11:
for Mathematica:
[1] s = SocketConnect[{"10.0.0.5", 5000}];
[2] WriteString[s, "dig:pin led6,1\r\n"];
[3] WriteString[s, "dig:pin? led6\r\n"]; Pause[.1]; ReadString[s, EndOfBuffer]

for Octave:
> pkg install -forge sockets % I used instead: $ sudo apt-get install octave-sockets
> pkg load sockets
> s=socket(); connect(s, struct("addr", "10.0.0.5", "port", 5000));
> send(s,['dig:pin led6,0' 13 10]) % cr/lf at end
> send(s,['dig:pin? led6' 13 10]); pause(.1); char(recv(s,256,MSG_DONTWAIT)) % max 256 bytes read
