Lets start with your basicEphys configuration.
In this section we will use the stimulator and the acquirer. The hardware has been configured in your startEphus file (review startEphus).
Acquirer
The acquirer is simply acquires data from the configured Channels. We only have one channel configured ('photodiode'). If you want to use more channels (e.g. for a temperature probe, field recording etc) you need to configure these channels in the startup file (e.g. startEphus). Select the Acq On checkbox.
Stimulator
The stimulator puts out data. Our startup file configured a qhole bunch of Channels corresponding to distinct hardware channels. It needs to be linked with the pulse directory (File\Open\ etc). Let's use 'shutter0' to drive a shutter. Make sure that all other channels have the Acq On checkbox deselected.
Warning
It is important that all active stimulator channels have pulses selected at all times. Otherwise an error will occur!
Make a shutter pulse (Width=100ms; Amp=5000 (note – this corresponds to 5 V); Delay=100) in a new Shutter pulse set and select it in the stimulator.
Running multiple programs simultaneously
Now select 'External' for the stimulator, acquirer, and ephys programs. All progrmas will now wait for an external trigger. Select Loop on the LoopGui. You should now hear the shutter opening as you cycle through the loop iterations.
