``random`` Random Numbers
|
||
=========================
|
||
|
||
This is a very simply test of ``/dev/random``. It simple collects random numbers
|
||
and displays them on the console.
|
||
|
||
Prerequistes:
|
||
|
||
- ``CONFIG_DEV_RANDOM`` – Support for ``/dev/random`` must be enabled in order to
|
||
select this example.
|
||
|
||
Configuration:
|
||
|
||
- ``CONFIG_EXAMPLES_RANDOM`` – Enables the ``/dev/random`` test.
|
||
- ``CONFIG_EXAMPLES_MAXSAMPLES`` – This is the size of the ``/dev/random`` I/O
|
||
buffer in units of 32-bit samples. Careful! This buffer is allocated on the
|
||
stack as needed! Default ``64``.
|
||
- ``CONFIG_EXAMPLES_NSAMPLES`` – When you execute the ``rand`` command, a number of
|
||
samples ranging from ``1`` to ``EXAMPLES_MAXSAMPLES`` may be specified. If no
|
||
argument is specified, this is the default number of samples that will be
|
||
collected and displayed. Default ``8``.
