Requirements
|
||
|
|
************
|
||
|
|
|
||
|
|
This shield can only be used with a board which provides a configuration
|
||
|
|
for Arduino connectors and defines node aliases for SPI and GPIO interfaces
|
||
|
|
(see :ref:`shields` for more details).
|
||
|
|
|
||
|
|
Programming
|
||
|
|
***********
|
||
|
|
|
||
|
|
