Overview
********

The sample sets up an LED to be toggled when a timer compare event is triggered.

User interface
**************

LED 0:
   Lit when the device is initialized.

LED 1:
   Blinking when the timer is running.

Building and running
********************

This sample can be found under :file:`samples/peripherals/ppi/` in the |BMshort| folder structure.

Testing
=======

You can test this sample by performing the following steps:

1. Compile and program the application.
#. Connect to the kit that runs this sample with a terminal emulator (for example, the `Serial Terminal app`_).
#. Reset the kit.
#. In the Serial Terminal, observe that the ``PPI sample initialized`` message is printed.
#. Observe that **LED 1** is blinking.
