Erwin Rol 3ff4d7409f samples: random: Add sentinel to check for buffer overflows 
Initialize the buffer to 0 and read one byte less than the
buffer size. The result should be that the last byte of
the buffer always stays 0. This way it is possible to verify
it the driver does not write outside the buffer.

Title: Random

Description:

A simple random number generation example

--------------------------------------------------------------------------------

Building and Running Project:

This project writes an infinite series of random numbers to the
console, 10 per second.

It can be built and executed on frdm_k64f as follows:

    make

Sample Output:

Random Example! arm
