=========

|
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 ``device_db.pyon`` device database file which contains a ``comm`` device (an example is provided in ``examples/master/device_db.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 ``device_db.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 startup and idle kernels 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'
|
|
|
