Digital Ins |
|
Pin x |
Lit (green) when digital input is detected on the pin. |
Digital Outs |
|
Pin x |
Click to enable digital output on the pin. |
Clock Outputs |
|
Word clock |
Click to enable NION word clock output on pin 6 for synchronization of external devices. The sample rate used for this clock is the sample rate specified for the project you are running on the NION. To view the project sample rate, on the File menu, click Project Properties. |
Frame clock |
Click to enable NION frame clock output on pin 7 for synchronization of external devices. |
Vector clock |
Click to enable NION vector clock output on pin 8 for synchronization of external devices. |
Analog Ins |
|
Value |
Displays a representation of the input voltage level range. The minimum value is represented by zero and the maximum by 1.0. The values are shown for 1K, 10K 12V, 10K 24V, 1K self-powered and 10K self-powered. Typically, these inputs are physically connected to a potentiometer. Tip: The knob control cannot be gestured, but you can duplicate it and wire the copy to other controls in your design. This enables you to pass the values to other controls. |
Calibrate |
Sets the range of recognized input values arriving into the analog inputs. After the potentiometer has been installed, and you are ready to set the minimum and maximum values:
|
Min Calibration |
The minimum recognized analog input value (set during the calibration process). |
Max Calibration |
The maximum recognized analog input value (set during the calibration process). |
Squelch |
A control noise squelch that adjusts the bit resolution of the analog input. The higher the squelch value, the greater the change in value required in the input in order for it to be recognized as a change. This is typically used when the input signal is fluctuating because of noise. We recommend that you use the minimum squelch value possible in order to stop the input signal fluctuating. |
Rotary Encoder |
|
Value |
Displays the input value for a rotary encoder wired to the GPIO port. The value increases when the rotary encoder is moved in one direction and decreased when it is moved in the other. You can also set the value manually by gesturing the knob. |
Sensitivity |
Adjusts the bit resolution of the analog input. The higher the value, the greater the change in value required in order for it to be recognized as a change. This is typically used when the input signal is fluctuating because of noise. |
Reverse |
When clicked, reverses the direction in which the rotary encoder must be moved in order to increase or decrease the value. |
Wrap |
When clicked, there will be no minimum or maximum value for the control knob. It can be continually gestured in either direction to adjust its value without reaching any end stops. |
Raw |
|
Special Enable |
When clicked, enables the user to monitor the raw (unfiltered) input and output values on a particular GPIO pin. |
Output Enable |
When clicked, enables the user to monitor the raw (unfiltered) output values by clicking the Output button. This button is used by administrators to control user access to the output monitoring function. |
Output |
When clicked, switches on the output pin. |
Input |
Lit (pink) when a voltage of 2V or greater is fed into the input connector. |
ADC |
Analog to Digital Conversion (of input signals). Shows information on signals arriving on the pin. When a potentiometer is connected to the pin, for example, it will show different readings as the knob is turned. |
Encoder |
Shows readings for input or output signals, depending on how the pin is being used. Up to 4096 distinct values can be detected for an input. |
High Current Outs |
|
Pin x |
Click to enable high current output on the pin. Provides 11.5V DC and up to 500mA of current.. |
PWM Outs |
|
Pin x |
Adjusts the pulse width on the output pin. The range is 0 to 1. Provides 25KHz PWM output. This is handy for driving LEDs (with the addition of a resistor). |
