-# Documentation for Stanford Research DG645 device and ophyd class
-This device allows to create TTL pulse for hardware trigger control of stages, detectors and more.
-It can be operate on external and/or internal triggering with up to 5 signals (T0, AB, CD, EF, GH) that can be generated for single or burst triggers.
-A detailed description of all functionality can be found in the [manual](https://www.thinksrs.com/downloads/pdfs/manuals/DG645m.pdf) of the device online. 
-The DG645 is for instance used for hardware triggering for fly scans at cSAXS.
-As for all EPIC devices, you need to ensure that the EPICS IOC is running to be able to control the device.
-This readme relates to the implementation of the devices as an ophyd class done in DelayGeneratorDG645.py. 
-## Integration of device in IPython kernel
-To add the device within IPython, proceed with the following steps:
-```Python
-from ophyd_devices.epics.devices.DelayGeneratorDG645 import DelayGeneratorDG645
-ddg4 = DelayGeneratorDG645(prefix='delaygen:DG1:',name='DDG4')
-```
-with prefix and name matching the settings within the EPIC's IOC.
-## TODO Integration of device in BEC device config!
-to be tested too
-## DDG645 ophyd class wrapper
-***Control trigger source***
-```Python
-ddg4.source.set(value:int)
-# int between 0 and 6
-```
-with *int* 
-- 0: internal, 1: ext rising edge, 2: ext falling edge, 3: SS ext rise edge, 4: SS ext falling edge, 5: Single shot, 6: line
-See manual for more details, most commonly used 0,1,2. 
-***Control width and delay of for instance channel AB***
-```Python
-ddg4.channelAB.width.set(1e-3) # setpoint in s
-ddg4.channelAB.width.read()
-ddg4.channelAB.delay.set(1e-3) # setpoint in s
-```
-***Burst mode***
- Check page 26 of manual for details.
-```Python
-ddg4.burstEnable(count:int, delay:float, period:float, config="first")
-# with
-# count: number of burst triggers on all channels: integer>0
-# delay: initial delay before first trigger in s:>0
-# period: repetition rate for triggers in s:>0, e.g. exposure time + readout time 
-# config Whether T0 fires off for all or only first trigger in burst sequence: "all" or "first"
-# for example
-ddg4.burstEnable(50, 0.015, 0.05, config="first")
-```
