iCon Outputs

When an iCon is attached to the Pynapse Behavioral Controller in the General Tab, an additional iCon tab appears. This gives you a unified interface that lets you configure the iCon inputs/outputs directly within Pynapse and integrates them in the Python code editor.

iCon Tab

Configure the iCon inputs/outputs in the iCon tab. See Logic Output Processor in the Synapse Manual for information on setting up the iCon outputs how to convert Pynapse function calls to physical hardware events.

iCon Tab

Run-time Interface

The run-time interface has a button for each output and an LED indicator that shows the current state of the output. For the iM10, additional options that were available during design-time can also be modified during run-time.

iCon Run-time Interface

Click an output to manually toggle its state (on/off). Hold down CTRL and click an output to 'mute' it. This prevents Pynapse from triggering the output.

Output Methods

All output methods have the form p_Rig.{OUTPUT_NAME}.{METHOD}. Type p_ in the Pynapse Code Editor and let the code completion do the work for you. The name of each method gets replaced with the name of your actual output, so if you name the output 'Reward' then p_Rig.Reward.fire() is an available method.

Manual Control

Manual turn outputs on, off, or fires a pulse waveform during runtime. Useful for stimulus/ reward presentation.

fire

p_Rig.MyOutput.fire()

This is only available if Triggered Pulse is selected.

Quickly pulse the output. If Duration is non-zero, the output will stay high for that set duration. Set Duration to zero to trigger a single sample pulse.

Example

Trigger an output when the input goes high.

class Always:   #StateID = 0

    def s_MyInput_pass():
        p_Rig.MyOutput.fire()

turnOn

p_Rig.MyOutput.turnOn()

Turn the output on indefinitely. This is only available if Triggered Pulse is not selected.

Example

Link an input status to an output.

class Always:   #StateID = 0

    def s_MyInput_rise():
        p_Rig.MyOutput.turnOn()

    def s_MyInput_fall():
        p_Rig.MyOutput.turnOff()

turnOff

p_Rig.MyOutput.turnOff()

Turn the output off. This is only available if Triggered Pulse is not selected.

Example

Link an input status to an output.

class Always:   #StateID = 0

    def s_MyInput_rise():
        p_Rig.MyOutput.turnOn()

    def s_MyInput_fall():
        p_Rig.MyOutput.turnOff()

setMute

p_Rig.MyOutput.setMute(muted)

Mute the output so it can't trigger, or unmute it.

Inputs Type Description
muted bool Change the output mute status (True/False or 1/0)

Duration Settings

setDuration

p_Rig.MyOutput.setDuration(dur_sec)

Override the output Duration setting. This is only available if Triggered Pulse is enabled and Duration is greater than 0.

Inputs Type Description
dur_sec float Duration of the output pulse when triggered with fire, in seconds
Example

Modify the pulse shape and output value based on performance.

def s_State_enter():
    # if more than 5 successful trials, decrease the output pulse time by 50 ms.
    if p_Metric.success.read() > 5:
        p_Metric.pulse_dur.dec(delta=0.05)
        p_Rig.MyOutput.setDuration(p_Metric.pulse_dur.read())

Status

Get information on the current state of the output.

isOn

p_Rig.MyOutput.isOn()

Returns true if the output is currently true.

Example

When entering a state, check if an output is already true.

def s_state_enter():
    if p_Rig.MyOutput.isOn():
        print('MyOutput is on')
    else:
        print('MyOutput is off')    

isOff

p_Rig.MyOutput.isOff()

Returns true if the output is currently false.

Example

When entering a state, check the status of the output.

def s_state_enter():
    if p_Rig.MyOutput.isOff():
        print('MyOutput is off')
    else:
        print('MyOutput is on')    

iM10 Output Settings

The iM10 has analog outputs. These functions override the analog output settings at runtime. See iM10 Analog Outputs for more information.

setAtten

p_Rig.MyInput.setAtten(v)

Set the output Attenuation, in dB. This is only available if Waveform Shape is User, Tone, White Noise, Pink Noise, Square, Clock, or PWM.

Inputs Type Description
v float Set the output attenuation, in dB

setFreq

p_Rig.MyInput.setFreq(v)

Set the output Frequency, in Hertz. This is only available if Waveform Shape is Tone, Square, or Clock.

Inputs Type Description
v float Set the output frequency, in Hz

setVolt

p_Rig.MyInput.setVolt(v)

Set the output voltage, in Volts. This is only available if Waveform Shape is DC Voltage.

Inputs Type Description
v float Set the output voltage, in V

setPeriod

p_Rig.MyInput.setPeriod(v)

Set the output period, in ms. This is only available if Waveform Shape is PWM.

Inputs Type Description
v float Set the output period, in ms

setWidth

p_Rig.MyInput.setWidth(v)

Set the output width, in ms. This is only available if Waveform Shape is PWM.

Inputs Type Description
v float Set the output width, in ms
