This tool is the preferred way of handling simple ARTIQ controllers. Instead of writing a client for very simple cases you can just use this tool in order to call remote functions of an ARTIQ controller.
Listing existing targets
The
list-targets
sub-command will print to standard output the target list of the remote server:$ artiq_rpctool.py hostname port list-targets
Listing callable functions
The
list-methods
sub-command will print to standard output a sorted list of the functions you can call on the remote server's target.The list will contain function names, signatures (arguments) and docstrings.
If the server has only one target, you can do:
$ artiq_rpctool.py hostname port list-methods
Otherwise you need to specify the target, using the
-t target
option:$ artiq_rpctool.py hostname port list-methods -t target_name
Remotely calling a function
The
call
sub-command will call a function on the specified remote server's target, passing the specified arguments. Like with the previous sub-command, you only need to provide the target name (with-t target
) if the server hosts several targets.The following example will call the
set_attenuation
method of the Lda controller with the argument5
:$ artiq_rpctool.py ::1 3253 call -t lda set_attenuation 5
In general, to call a function named
f
with N arguments named respectivelyx1, x2, ..., xN
you can do:$ artiq_rpctool.py hostname port call -t target f x1 x2 ... xN
You can use Python syntax to compute arguments as they will be passed to the
eval()
primitive. The numpy package is available in the namespace asnp
. Beware to use quotes to separate arguments which use spaces:$ artiq_rpctool.py hostname port call -t target f '3 * 4 + 2' True '[1, 2]' $ artiq_rpctool.py ::1 3256 call load_sample_values 'np.array([1.0, 2.0], dtype=float)'
If the called function has a return value, it will get printed to the standard output if the value is not None like in the standard python interactive console:
$ artiq_rpctool.py ::1 3253 call get_attenuation 5.0 dB
This tool compiles an experiment into a ELF file. It is primarily used to prepare binaries for the default experiment loaded in non-volatile storage of the core device.
Experiments compiled with this tool are not allowed to use RPCs, and their run
entry point must be a kernel.

This tool compiles key/value pairs into a binary image suitable for flashing into the flash storage space of the core device.
.. argparse:: :ref: artiq.frontend.artiq_mkfs.get_argparser :prog: artiq_mkfs
The artiq_coreconfig tool allows to read, write and remove key-value records from the :ref:`core-device-flash-storage`.
It also allows to erase the entire flash storage area.
To use this tool, you need to specify a ddb.pyon
DDB file which contains a comm
device (an example is provided in artiq/examples/master/ddb.pyon
).
This tells the tool how to connect to the core device (via serial or via TCP) and with which parameters (baudrate, serial device, IP address, TCP port).
When not specified, the artiq_coreconfig tool will assume that there is a file named ddb.pyon
in the current directory.
To read the record whose key is mac
:
$ artiq_coreconfig -r mac
To write the value test_value
in the key my_key
:
$ artiq_coreconfig -w my_key test_value $ artiq_coreconfig -r my_key b'test_value'
You can also write entire files in a record using the -f
parameter:
$ echo "this_is_a_test" > my_filename $ artiq_coreconfig -f my_key my_filename $ artiq_coreconfig -r my_key b'this_is_a_test\n'
You can write several records at once:
$ artiq_coreconfig -w key1 value1 -f key2 filename -w key3 value3
To remove the previously written key my_key
:
$ artiq_coreconfig -d my_key
To erase the entire flash storage area:
$ artiq_coreconfig -e
You don't need to remove a record in order to change its value, just overwrite it:
$ artiq_coreconfig -w my_key some_value $ artiq_coreconfig -w my_key some_other_value $ artiq_coreconfig -r my_key b'some_other_value'
