EKT Arduino R3, Quick Start Manual

}

The function

getTouchStatus()

actually returns at 16-bit value which gives the status of each button. 

The status of 1 indicates that an electrode is being activated.

language:

c

    int

getTouchStatus()

{

  int

touch;

  touch

=

mpr121Read(0x01)

<<

8;

  touch

|=

mpr121Read(0x00);

  return

touch;

}

Now that you have basic communication up and running with your shield, you can start integrating 
this into projects. If you haven’t yet connected anything to electrodes 9, 10 and 11, consider adding in 
additional buttons here. You will also need to update the code. You’ll want to add the following block 
of code into the example sketch right beforeSerial.println(digits);. You can change the digits values to 
have the buttons output different values instead of “A”, “B”, or “C”.

    else

if

(touchstatus

&

(1

<<

ELE9))

{

  digits

=

'A';

}

else

if

(touchstatus

&

(1

<<

ELE10))

{

  digits

=

'B';

}

else

if

(touchstatus

&

(1

<<

ELE11))

{

  digits

=

'C';

//do nothing if more than one button is pressed, or if all are released
else if (touchNumber == 0)

;
