# rotaryPulse

Encoder functions in the rotaryPulse category. Information on this category [here.](/ddc/switch-library/encoders.md#rotarypulse)

#### rotaryPulse()

{% tabs %}
{% tab title="Description" %}
Standard incremental encoder setup. Rotating CW will give a button pulse, rotating CCW will give a button pulse with a button number 1 value higher.
{% endtab %}

{% tab title="Example" %}
`void rotaryPulse(int row, int column, bool reverse)`

For an encoder with pins A and B to columns 3 and 4. Common pin to row 2:

`rotaryPulse(2, 3, false);`

The button numbers used is determined by the number written in the block for the A pin. B pin block will not be read. If button number was set to 15, the switch will use buttons 15 and 16. The `reverse` part of the function will switch the button numbers if set to `true`.
{% endtab %}

{% tab title="Requirements" %}

* 2 button numbers
  {% endtab %}
  {% endtabs %}

#### <mark style="background-color:orange;">rotaryPulseBite()</mark>

{% tabs %}
{% tab title="Description" %}
Standard incremental encoder setup. Rotating CW will give a button pulse, rotating CCW will give a button pulse with a button number 1 value higher.

In addition, this switch can set the bite point of your clutches. Works in combination with [biteButton().](/ddc/switch-library/function-button.md#bitebutton) The button presses will not trigger when setting bite point.&#x20;
{% endtab %}

{% tab title="Example" %}
`void rotaryPulseBite(int row, int column, bool reverse)`

For an encoder with pins A and B to columns 3 and 4. Common pin to row 2:

`rotaryPulseBite(2, 3, false);`

The button numbers used is determined by the number written in the block for the A pin. B pin block will not be read. If button number was set to 15, the switch will use buttons 15 and 16. The `reverse` part of the function will switch the button numbers and increase/decrease bite point if set to `true`.
{% endtab %}

{% tab title="Requirements" %}

* 2 button numbers
* biteButton() to set bite point
  {% endtab %}
  {% endtabs %}
