Set the Simulation for a DAQ Controller
A Simulation may be set on any SimulationDaqController subclass. Symphony comes with two built-in SimulationDaqController subclasses:
symphonyui.builtin.daqs.HekaSimulationDaqController- Manages a simulated HEKA (InstruTECH) DAQ interface (requires no attached hardware).symphonyui.builtin.daqs.NiSimulationDaqController- Manages a simulated National Instruments DAQ interface (requires no attached hardware).
This tutorial shows how to set the simulation for a SimulationDaqController.
Step 1: Open or create a rig description
Open or recreate the "Demo" rig description so you have something to work with.
classdef Demo < symphonyui.core.descriptions.RigDescription
methods
function obj = Demo()
import symphonyui.builtin.daqs.*;
import symphonyui.builtin.devices.*;
daq = HekaSimulationDaqController();
obj.daqController = daq;
% Add a MultiClamp 700B device with name = Amp, channel = 1
amp = MultiClampDevice('Amp', 1).bindStream(daq.getStream('ao0')).bindStream(daq.getStream('ai0'));
obj.addDevice(amp);
% Add a LED device with name = Green LED, units = volts
green = UnitConvertingDevice('Green LED', 'V').bindStream(daq.getStream('ao1'));
obj.addDevice(green);
end
end
end
Step 2: Set the simulation for the controller
You set the simulation for a simulation controller by setting its "simulation" property to a desired Simulation.
Add an additional line after instantiating the simulation controller (i.e. daq = HekaSimulationDaqController) and set its "simulation" property to an instance of the "Demo" simulation.
classdef Demo < symphonyui.core.descriptions.RigDescription
methods
function obj = Demo()
import symphonyui.builtin.daqs.*;
import symphonyui.builtin.devices.*;
daq = HekaSimulationDaqController();
daq.simulation = edu.washington.riekelab.simulations.Demo();
obj.daqController = daq;
...
end
end
end
| Note: For this to work, you must have completed the "Write a Simulation" tutorial so that the "Demo" simulation exists and replace the `edu.washington.riekelab` prefix with your own package prefix. |
You now have a rig description with a DAQ controller using the "Demo" Simulation.
