Overview
|
||
********
|
||
|
||
The Freedom development board platform supports the MCR20A 2.4GHZ wireless
|
||
transceiver. The FRDM-CR20A evaluation board is a small, low-power,
|
||
cost-effective reference design for the MCR20A transceiver in a shield form
|
||
factor, compatible with existing Freedom development platforms, such as
|
||
:ref:`frdm_k64f`.

Programming
|
||
***********
|
||
|
||
Set ``-DSHIELD=frdm_cr20a`` when you invoke ``west build`` or ``cmake`` in your
|
||
Zephyr application. For example:
|
||
|
||
.. zephyr-app-commands::
|
||
:zephyr-app: samples/net/wpanusb
|
||
:tool: all
|
||
:board: frdm_k64f
|
||
:shield: frdm_cr20a
