iCon Inputs

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 Input Processor in the Synapse Manual for information on setting up the iCon inputs and pre-processing them so Pynapse can capture event changes.

iCon Tab

Run-time Interface

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

iCon Run-time Interface

Click on the input name to manually trigger it. Hold down CTRL and click an input name to 'mute' it. This prevents the input from triggering Pynapse events.

Slot Methods for Responding to Input States

These input slots capture status information about the inputs. They are available as method definitions inside Pynapse states for each input. Write a method with this name to react to the corresponding event.

Slot name	Operation	Event
s_Input1_rise()	Status	input changed to true
s_Input1_fall()	Status	input changed to false
s_Input1_active()	Duration	input passed the 'Time to Active' duration test (see Duration Testing)
s_Input1_pass()	Duration	input passed the 'Time to Pass' duration test (see Duration Testing)
s_Input1_fail()	Duration	input failed the 'Time to Pass' duration test, after passing 'Time to Active' (see Duration Testing)

Note

The name of each slot method ('Input1' above) gets replaced with the name of your actual input, so if you name the input 'NosePoke' then s_NosePoke_rise() is an available slot.

Example

Move through behavioral states based on status of MyInput

class PreTrial:
    def s_MyInput_rise():
        p_State.switch(StartTrial)

class StartTrial:    # StateID = ?
    def s_MyInput_active():
        p_State.switch(ActiveState)

    def s_MyInput_fall():
        p_State.switch(PreTrial)

class ActiveState:    # StateID = ?
    def s_MyInput_pass():
        p_State.switch(PassState)

    def s_MyInput_fail():
        p_State.switch(FailState)

Methods

All input methods have the form p_Rig.{INPUT_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 input 'NosePoke' then p_Rig.NosePoke.isOn() is an available method.

Duration Settings

Override the duration test 'Time to Active' setting. This is only available if 'Duration Testing' is enabled on the input.

Example

Modify the timing test based on performance.

def s_State_enter():
    # if more than 5 successful trials, increase the time to active by 50 ms.
    if p_Metric.success.read() > 5:
        p_Metric.active_time.inc(delta=0.05)
        p_Rig.MyInput.setActTime(p_Metric.active_time.read())

setPassTime

p_Rig.MyInput.setPassTime(passtime_sec)

Override the duration test 'Time to Pass' setting. This is only available if 'Duration Testing' is enabled on the input.

Inputs	Type	Description
passtime_sec	float	Time to Pass, in seconds

Example

Modify the timing test based on performance.

def s_State_enter():
    # if more than 5 successful trials, increase the time to pass by 50 ms.
    if p_Metric.success.read() > 5:
        p_Metric.pass_time.inc(delta=0.05)
        p_Rig.MyInput.setPassTime(p_Metric.pass_time.read())

setRateThresh

p_Rig.MyInput.setRateThresh(ratethr_hz)

Override the rate testing 'Rate Threshold' setting. This is only available if 'Rate Testing' is enabled on the input.

Inputs	Type	Description
ratethr_hz	float	Rate testing threshold, in Hertz

Example

Modify the rate threshold based on performance.

def s_State_enter():
    # if more than 5 successful trials, increase the rate threshold by 1 Hz.
    if p_Metric.success.read() > 5:
        p_Metric.rate_thresh.inc()
        p_Rig.MyInput.setRateThresh(p_Metric.rate_thresh.read())

Manual Control

Manual turn inputs on, off, or pulse during runtime. Useful for debugging.

manualOn

p_Rig.MyInput.manualPulse()
