== Hardware ==

The sensor directly interfaces to the 3.3V SPI port of the autopilots and is supplied by +3.3V.

== Usage ==

To use it load the baro_scp module:
{{Box Code|conf/airframes/myplane.xml|
<source lang="xml">
<modules>
...
<load name="baro_scp.xml"/>
</modules>
</source>
}}

=== Configuration ===

To see the sensors data in the log file set the SENSOR_SYNC_SEND in your airframe file. Every time new data is available it will be sent directly.
{{Box Code|conf/airframes/myplane.xml|
<source lang="xml">
<modules>
...
<load name="baro_scp.xml">
<define name="SENSOR_SYNC_SEND"/>
</load>
</modules>
</source>
}}

===Result message===

There is no conversion needed so the raw data is output, the pressure is given in 1/100 of Pascal.
{{Box Code|conf/messages.xml|

<field name="press" type="uint32" unit="Pa"/>
