"""
DDG1 delay generator
This module implements the DDG1 delay generator logic for the CSAXS beamline.
The attached PDF trigger_scheme_ddg1_ddg2.pdf provides a more detailed overview of
the trigger scheme. If the logic changes in the future, it is highly recommended to
update the PDF accordingly.
The DDG1 is the main trigger delay generator for the CSAXS beamline. It will
receive either a soft trigger from BEC (depending on the scan type) or a hardware trigger
from a beamline device (e.g. the Galil stages). It is responsible for opening the shutter
and sending a trigger to the Delay Generator CSAXS (DDG2), which in turn will
send the trigger to the detectors. DDG1 will not be witout burst mode, but rather in standard
mode creating delays for the channels ab, cd, ef, gh.
A brief summary of the DDG1 logic:
DELAY PAIRS:
- DelayPair ab is connected to the EXT/EN of DDG2.
- DelayPair cd is connected to the SHUTTER.
- DelayPair ef is connected to an OR gate together with the detector
PULSE train for the MCS card. The MCS card needs one extra pulse to forward points.
DELAY CHANNELS:
- a = t0 + 2ms (2ms delay to allow the shutter to open)
- b = a + 1us (short pulse)
- c = t0
- d = a + exp_time * burst_count + 1ms (to allow the shutter to close)
- e = d
- f = e + 1us (short pulse to OR gate for MCS triggering)

Delay Generator Stanford Research DG645. This implements an interface for the DG645 delay generator.
Detailed information can be found in the manual:

The DG645 has 8 channels, each with a delay and pulse width. The channels are implemented as DelayPair objects (AB etc.).
Each pair has a TTL pulse width, delay and a reference signal to which they are being triggered.
In addition, the io layer allows setting amplitude, offset and polarity for each pair.

EPICS SIS38XX Multichannel Scaler (MCS) Interface
This module provides an interface to the SIS3801/SIS3820 multichannel scaler (MCS) cards via EPICS.
It focuses on the implementation for the SIS3820 model, as input/output modes differ between SIS3801
and SIS3820. It supports both MCS and scaler record operations, enabling configuration and control of
acquisition parameters such as dwell time, channel advance mode, and input/output settings.
The module facilitates data acquisition by managing FIFO buffers and simulating conventional
MCS behavior through memory buffers.
At cSAXS, the SIS3820 model is used, which supports 32 channels.

"""
This module provides a Camera class for handling IDS cameras using the pyueye library,
that links to the vendors C++ SDK. Details about the camera's C++ SDK API can be found
in the IDS Software Suite 4.96.1 documentation:
(https://www.1stvision.com/cameras/IDS/IDS-manuals/uEye_Manual/sdk_einleitung_schnellstart.html)
Here, we follow a procedure to set up the camera, configure its basic parameters and
allow automated capturing of images. The IDSCameraObject class is the low-level interface,
and requires the pyueye library and appropriate DLL files on the system. The Camera class
provides a high level interface which only creates the IDSCameraObject instance when the
on_connect method is called. This allows for lazy initialization of the camera, and
CI/CD pipelines can run without the pyueye library or the related DLLs installed on the system.

"""
Generic integration of JungfrauJoch backend with Eiger detectors
for the cSAXS beamline at the Swiss Light Source.
The WEB UI is available on http://sls-jfjoch-001:8080
NOTE: this may not be the best place to store this information. It should be migrated to
beamline documentation for debugging of Eiger & JungfrauJoch.
The JungfrauJoch server for cSAXS runs on sls-jfjoch-001.psi.ch
User with sufficient rights may use:
- sudo systemctl restart jfjoch_broker
- sudo systemctl status jfjoch_broker
to check and/or restart the broker for the JungfrauJoch server.
Some extra notes for setting up the detector:
- If the energy on JFJ is set via DetectorSettings, the variable in DatasetSettings will be ignored
- Changes in energy may take time, good to implement logic that only resets energy if needed.
- For the Eiger, the frame_time_us in DetectorSettings is ignored, only the frame_time_us in
the DatasetSettings is relevant
- The bit_depth will be adjusted automatically based on the exp_time. Here, we need to ensure
that subsequent triggers properly
consider the readout_time of the boards. For Jungfrau detectors, the difference between
count_time_us and frame_time_us is the readout_time of the boards. For the Eiger, this needs
to be taken into account during the integration.
- beam_center and detector settings are required input arguments, thus, they may be set to wrong
values for acquisitions to start. Please keep this in mind.
Hardware related notes:
- If there is an HW issue with the detector, power cycling may help.
- The sls_detector package is available on console on /sls/X12SA/data/gac-x12sa/erik/micromamba
- Run: source setup_9m.sh # Be careful, this connects to the detector, so it should not be
used during operation
- Useful commands:
- p highvoltage 0 or 150 (operational)
- g highvoltage
- # Put high voltage to 0 before power cylcing it.
- telnet bchip500
- cd power_control_user/
- ./on
- ./off
Further information that may be relevant for debugging:
JungfrauJoch - one needs to connect to the jfj-server (sls-jfjoch-001)

# Macros
This directory is intended to store macros which will be loaded automatically when starting BEC.
Macros are small functions to make repetitive tasks easier. Functions defined in python files in this directory will be accessible from the BEC console.
Please do not put any code outside of function definitions here. If you wish for code to be automatically run when starting BEC, see the startup script at csaxs_bec/bec_ipython_client/startup/post_startup.py
For a guide on writing macros, please see: https://bec.readthedocs.io/en/latest/user/command_line_interface.html#how-to-write-a-macro
