Highlights:
"hw_rev": "v2.1") to use the correct conversion factor.aqctl_coreanalyzer_proxy typically running on the master
machine, similarly to aqctl_moninj_proxy.EntryArea widget which allows argument entry widgets to be used in applets.quickstyle option, EnumerationValue entry widgets can now alternatively display
its choices as buttons that submit the experiment on click.NumberValue already did in earlier ARTIQ versions.float, or List[...]) can now be used in type annotations on
kernel functions.artiq_coremgmt can be used. This allows the user to inspect logs, change
configuration options, update the firmware, and reboot the device.Breaking changes:
SimpleApplet now calls widget constructors with an additional ctl parameter for control
operations, which includes dataset operations. It can be ignored if not needed. For an example usage,
refer to the big_number.py applet.SimpleApplet and TitleApplet now call data_changed with additional parameters. Derived applets
should change the function signature as below:# SimpleApplet def data_changed(self, value, metadata, persist, mods) # SimpleApplet (old version) def data_changed(self, data, mods) # TitleApplet def data_changed(self, value, metadata, persist, mods, title) # TitleApplet (old version) def data_changed(self, data, mods, title)
Accesses to the data argument should be replaced as below:
data[key][0] ==> persist[key] data[key][1] ==> value[key]
ndecimals parameter in NumberValue and Scannable has been renamed to precision.
Parameters after and including scale in both constructors are now keyword-only.
Refer to the updated no_hardware/arguments_demo.py example for current usage.almazny_hw_rev in the JSON description.

artiq.wavesynth has been removed.Highlights:
sif_sync, exposed upconverter calibration
and enabling/disabling of upconverter LO & RF outputs, added helpers to align Phaser updates to the
RTIO timeline (get_next_frame_mu()).get(), get_mu(), get_att(), and get_att_mu() functions added for AD9910 and AD9912.aqctl_moninj_proxy controller.rtio_clock supports multiple clocking settings, deprecating the usage
of compile-time options.artiq_ddb_template generates edge-counter keys that start with the key of the corresponding
TTL device (e.g. ttl_0_counter for the edge counter on TTL device ttl_0).artiq_master now has an --experiment-subdir option to scan only a subdirectory of the
repository when building the list of experiments.scheduler.check_termination() to test if the user
has requested graceful termination.artiq_coremgmt reboot now reloads gateware as well, providing a more thorough and reliable
device reset (7-series FPGAs only).afws_client
(subscribers only). Self-compilation remains possible.Breaking changes:
target parameter needs to be set to rv32ima for Kasli 1.x and to rv32g for all
other boards. Freshly generated device database templates already contain this update.Phaser.init() now disables all Kasli-oscillators. This avoids full power RF output being
generated for some configurations.ADF5356.sync(). This avoids the need of an extra delay before
calling ADF5356.init().set_dataset(..., save=...) is no longer supported.PCA9548 I2C switch class was renamed to I2CSwitch, to accommodate support for PCA9547,
and possibly other switches in future. Readback has been removed, and now only one channel per
switch is supported.Highlights:
+, /), matrix multiplication (@) and
multidimensional indexing are supported; slices and views are not yet.numpy.sin), both for scalar arguments and implicitly
broadcast across multidimensional arrays.AssertionErrors instead of aborting kernel
execution.ValueError.voltage_to_mu()
ad9910:0x3fff (was 0x3ffe before).set_mu() that affects the ASF, FTW and POW registers
instead of the single-tone profile register.clk_sel parameters:
"XO", "SMA", and "MMCX". Passing an integer is backwards compatible.run() fails.panic_reset 1 now correctly resets the kernel CPU as well if
communication CPU panic occurs.type parameter specifying the output as int or float
--identifier-str has been added to many targets to aid
with reproducible builds.Breaking changes:
artiq_netboot has been moved to its own repository at
https://git.m-labs.hk/m-labs/artiq-netboot
quamash has been replaced with qasync.artiq.coredevice.suservo.SUServo constructor now accepts two device name lists,
cpld_devices and dds_devices, rather than four individual arguments.artiq_client
determines which experiment to submit (consistent with artiq_run).Highlights:
artiq.coredevice.edge_counter for
the core device driver and artiq.gateware.rtio.phy.edge_counter/
artiq.gateware.eem.DIO.add_std for the gateware components.artiq.language.environment.HasEnvironment.append_to_dataset.Breaking changes:
artiq.coredevice.ad9910.AD9910 and
artiq.coredevice.ad9914.AD9914 phase reference timestamp parameters
have been renamed to ref_time_mu for consistency, as they are in machine
units.command key set to facilitate sharing of devices between multiple
masters.-d/--dir and --srcbuild options of artiq_flash
has changed.aqctl_corelog now filters log messages below the WARNING level by default.
This behavior can be changed using the -v and -q options like the other
programs.-e/--experiment switch of artiq_run and artiq_compile
has been renamed -c/--class-name.artiq_devtool has been removed.artiq.protocols has been moved to a separate package sipyco.
artiq_rpctool has been renamed to sipyco_rpctool.The artiq.coredevice.ttl drivers no longer track the timestamps of
submitted events in software, requiring the user to explicitly specify the
timeout for count()/timestamp_mu(). Support for sync() has been dropped.
Now that RTIO has gained DMA support, there is no longer a reliable way for
the kernel CPU to track the individual events submitted on any one channel.
Requiring the timeouts to be specified explicitly ensures consistent API
behavior. To make this more convenient, the TTLInOut.gate_*() functions
now return the cursor position at the end of the gate, e.g.:
ttl_input.count(ttl_input.gate_rising(100 * us))
In most situations – that is, unless the timeline cursor is rewound after the
respective gate_*() call – simply passing now_mu() is also a valid
upgrade path:
ttl_input.count(now_mu())
The latter might use up more timeline slack than necessary, though.
In place of TTL(In)Out.sync, the new Core.wait_until_mu() method can
be used, which blocks execution until the hardware RTIO cursor reaches the
given timestamp:
ttl_output.pulse(10 * us) self.core.wait_until_mu(now_mu())
RTIO outputs use a new architecture called Scalable Event Dispatcher (SED), which allows building systems with large number of RTIO channels more efficiently. From the user perspective, collision errors become asynchronous, and non- monotonic timestamps on any combination of channels are generally allowed (instead of producing sequence errors). RTIO inputs are not affected.
The DDS channel number for the NIST CLOCK target has changed.
The dashboard configuration files are now stored one-per-master, keyed by the server address argument and the notify port.
The master now has a --name argument. If given, the dashboard is labelled
with this name rather than the server address.
artiq_flash targets Kasli by default. Use -t kc705 to flash a KC705
instead.
artiq_flash -m/--adapter has been changed to artiq_flash -V/--variant.
The proxy action of artiq_flash is determined automatically and should
not be specified manually anymore.
kc705_dds has been renamed kc705.
The -H/--hw-adapter option of kc705 has been renamed -V/--variant.
SPI masters have been switched from misoc-spi to misoc-spi2. This affects
all out-of-tree RTIO core device drivers using those buses. See the various
commits on e.g. the ad53xx driver for an example how to port from the old
to the new bus.
The ad5360 coredevice driver has been renamed to ad53xx and the API
has changed to better support Zotino.
artiq.coredevice.dds has been renamed to artiq.coredevice.ad9914 and
simplified. DDS batch mode is no longer supported. The core_dds device
is no longer necessary.
The configuration entry startup_clock is renamed rtio_clock. Switching
clocks dynamically (i.e. without device restart) is no longer supported.
set_dataset(..., save=True) has been renamed
set_dataset(..., archive=True).
On the AD9914 DDS, when switching to PHASE_MODE_CONTINUOUS from another mode,
use the returned value of the last set_mu call as the phase offset for
PHASE_MODE_CONTINUOUS to avoid a phase discontinuity. This is no longer done
automatically. If one phase glitch when entering PHASE_MODE_CONTINUOUS is not
an issue, this recommendation can be ignored.

--embed option of applets is replaced with the environment variable
ARTIQ_APPLET_EMBED. The GUI sets this enviroment variable itself and the
user simply needs to remove the --embed argument.EnvExperiment's prepare calls prepare for all its children.__getattr__'s returning RPC target methods are not supported anymore.
Controller driver classes must define all their methods intended for RPC as
members.archive=False to get_dataset.seconds_to_mu and mu_to_seconds have become methods of the core
device driver (use e.g. self.core.seconds_to_mu()).int(a, width=b) has been removed. Use int32(a) and int64(a).kc705_dds.artiq.coredevice.comm_tcp has been renamed artiq.coredevice.comm_kernel,
and Comm has been renamed CommKernel.analyze raises an exception.LinearScan and RandomScan have been consolidated into RangeScan.device_db = `` at the beginning, and replace any PYON
identifiers (``true, null, ...) with their Python equivalents
(True, None ...).aqctl_XXX instead of XXX_controller.comm device has been folded into the core device.
Move the "host" argument into the core device, and remove the comm device.aqctl_corelog must be running to forward
those logs to the master. See the example device databases to see how to
instantiate this controller. Using artiq_session ensures that a controller
manager is running simultaneously with the master.start_time and run_time are now stored as doubles of UNIX time,
rather than ints. The file names are still based on local time.No further notes.

The format of the influxdb pattern file is simplified. The procedure to
edit patterns is also changed to modifying the pattern file and calling:
artiq_rpctool.py ::1 3248 call scan_patterns (or restarting the bridge)
The patterns can be converted to the new format using this code snippet:
from artiq.protocols import pyon
patterns = pyon.load_file("influxdb_patterns.pyon")
for p in patterns:
print(p)
The "GUI" has been renamed the "dashboard".
When flashing NIST boards, use "-m nist_qcX" or "-m nist_clock" instead of just "-m qcX" or "-m clock" (#290).
Applet command lines now use templates (e.g. $python) instead of formats (e.g. {python}).
On Windows, GUI applications no longer open a console. For debugging purposes, the console messages can still be displayed by running the GUI applications this way:
python3.5 -m artiq.frontend.artiq_browser python3.5 -m artiq.frontend.artiq_dashboard
(you may need to replace python3.5 with python) Please always include the console output when reporting a GUI crash.
The result folders are formatted "%Y-%m-%d/%H instead of "%Y-%m-%d/%H-%M". (i.e. grouping by day and then by hour, instead of by day and then by minute)
The parent keyword argument of HasEnvironment (and EnvExperiment)
has been replaced. Pass the parent as first argument instead.
During experiment examination (and a fortiori repository scan), the values of
all arguments are set to None regardless of any default values supplied.
In the dashboard's experiment windows, partial or full argument recomputation takes into account the repository revision field.
By default, NumberValue and Scannable infer the scale from the unit
for common units.
By default, artiq_client keeps the current persist flag on the master.
GUI state files for the browser and the dashboard are stores in "standard"
locations for each operating system. Those are
~/.config/artiq/2/artiq_*.pyon on Linux and
C:\Users\<username>\AppData\Local\m-labs\artiq\2\artiq_*.pyon on
Windows 7.
The position of the time cursor is kept across experiments and RTIO resets are manual and explicit (inter-experiment seamless handover).
All integers manipulated by kernels are numpy integers (numpy.int32, numpy.int64). If you pass an integer as a RPC argument, the target function receives a numpy type.

datasets.ndecimals = 0, scale = 1 and
step is integer.Experiments (your code) should use from artiq.experiment import *
(and not from artiq import * as previously)
Core device flash storage has moved due to increased runtime size. This requires reflashing the runtime and the flash storage filesystem image or erase and rewrite its entries.
RTIOCollisionError has been renamed to RTIOCollision
the new API for DDS batches is:
with self.core_dds.batch: ...
with core_dds a device of type artiq.coredevice.dds.CoreDDS.
The dds_bus device should not be used anymore.
LinearScan now supports scanning from high to low. Accordingly,
its arguments min/max have been renamed to start/stop respectively.
Same for RandomScan (even though there direction matters little).
