<title>Description</title>
<para> This is a read counter that counts the information from absolute position sensors (Hall effect sensor ...). </para>
<para> The block is used to read the rising edges detected on the interruption inputs of the Arduino board. These inputs are capable of stopping the main program during a change of state (edges of a signal) to execute a subroutine. The subroutine in this case is to increment a counter. </para>
<para> Pins 2 and 3 are the only pins of the Arduino Uno that support interrupts. On the Mega board, the pins are 2, 3 and 18 to 21. </para>
<para> Do note that the minimum sampling rate is 8 ms for this block. </para>
</refsection>
<refsection id="Dialogbox_INTERRUPT_SB">
<title>Dialog box</title>
<para> The device offers a menu that allows the declaration of the interrupt pin 2 or 3 on a UNO card (2, 3 or 18 to 21 for the MEGA board) and declaration of any digital pin 2 to 13 for a UNO card (2-53 for the MEGA board). </para>
<para> The card number can not be changed at this time. </para>
