Utilities

=========

|
|
|
Local running tool
|
|
------------------
|
|
|
|
.. argparse::
|
|
:ref: artiq.frontend.artiq_run.get_argparser
|
|
:prog: artiq_run
|
|
|
|
Remote Procedure Call tool
|
|
--------------------------
|
|
|
|
.. argparse::
|
|
:ref: artiq.frontend.artiq_rpctool.get_argparser
|
|
:prog: artiq_rpctool
|
|
|
|
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 argument ``5``::
|
|
|
|
$ artiq_rpctool.py ::1 3253 call -t lda set_attenuation 5
|
|
|
|
In general, to call a function named ``f`` with N arguments named
|
|
respectively ``x1, 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
|
|
as ``np``. 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
|

|
Static compiler
|
|
---------------
|
|
|
|
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.
|
|
|
|
.. argparse::
|
|
:ref: artiq.frontend.artiq_compile.get_argparser
|
|
:prog: artiq_compile
|
|
|
|
Flash storage image generator
|
|
-----------------------------
|
|
|
|
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
|
|
|
|
.. _core-device-access-tool:
|
|
|
|
Core device access tool
|
|
-----------------------
|
|
|
|
The artiq_coretool utility allows to perform maintenance on the core device:
|
|
|
|
* read core device logs;
|
|
* as well as read, write and remove key-value records from the :ref:`core-device-flash-storage`;
|
|
* 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_coretool utility will assume that there is a file named ``ddb.pyon`` in the current directory.
|
|
|
|
|
|
To read the record whose key is ``mac``::
|
|
|
|
$ artiq_coretool cfg-read mac
|
|
|
|
To write the value ``test_value`` in the key ``my_key``::
|
|
|
|
$ artiq_coretool cfg-write -s my_key test_value
|
|
$ artiq_coretool cfg-read my_key
|
|
b'test_value'
|
|
|
|
You can also write entire files in a record using the ``-f`` parameter. This is useful for instance to write the ``idle`` kernel in the flash storage::
|
|
|
|
$ artiq_coretool cfg-write -f idle_kernel idle.elf
|
|
$ artiq_coretool cfg-read idle_kernel | head -c9
|
|
b'\x7fELF
|
|
|
|
You can write several records at once::
|
|
|
|
$ artiq_coretool cfg-write -s key1 value1 -f key2 filename -s key3 value3
|
|
|
|
To remove the previously written key ``my_key``::
|
|
|
|
$ artiq_coretool cfg-delete my_key
|
|
|
|
You can remove several keys at once::
|
|
|
|
$ artiq_coretool cfg-delete key1 key2
|
|
|
|
To erase the entire flash storage area::
|
|
|
|
$ artiq_coretool cfg-erase
|
|
|
|
You don't need to remove a record in order to change its value, just overwrite
|
|
it::
|
|
|
|
$ artiq_coretool cfg-write -s my_key some_value
|
|
$ artiq_coretool cfg-write -s my_key some_other_value
|
|
$ artiq_coretool cfg-read my_key
|
|
b'some_other_value'
|
|
|
|
.. argparse::
|
|
:ref: artiq.frontend.artiq_coretool.get_argparser
