cloud_sensor module

Get data from Cloud Sensor

• compute Liquid Water Content (LWC) value from PAYLOAD_FLOAT data
• get already computed LWC from PAYLOAD_COMMAND data

Example for airframe file

Add to your firmware section:

<module name="cloud_sensor"/>

Module functions

Init Functions

These initialization functions are called once on startup.

• cloud_sensor_init()

Periodic Functions

These functions are called periodically at the specified frequency from the module periodic loop.

• cloud_sensor_report()
  • Frequency in Hz: 2.
  • Autorun: TRUE
    Periodic function automatically starts after init.

Datalink Functions

Whenever the specified datalink message is received, the corresponing handler function is called.

• on message PAYLOAD_COMMAND call LWC_callback(buf)
• on message PAYLOAD_FLOAT call cloud_sensor_callback(buf)

Header Files

The following headers are automatically included in modules.h
