Detailed Description

The PiCamera class handles communication with the Raspberry Pi Camera.

Author

John Gaby

   This class allows you to connect to the Data server of the Raspberry
   Pi and receive information about the image frames processed by the
   camera.

   It also implements a time sync protocol to synchronize the clocks and
   performs keep-alive functions that detect a disconnect.

Member Function Documentation

clearStats()

void robotCore.PiCamera.clearStats

(

)

Clears the camera performance stats

connect()

void robotCore.PiCamera.connect	(	String	host,
		int	port
	)

Connects to the Raspberry Pi Data server

Parameters

host	- Specifies IP for the host
port	- Specifies the port (default is 5800)

dumpFrames()

void robotCore.PiCamera.dumpFrames

(

int

count

)

Instructs the Raspberry Pi to dump the last N frame to disk. This can be useful in debugging to obtain a record of what the camera saw.

Parameters

count

- Count of frames to dump (max 120)

endLogging()

void robotCore.PiCamera.endLogging

(

)

Ends logging and closes the log file

endPiLog()

void robotCore.PiCamera.endPiLog

(

)

Ends the Raspberry Pi logging

getRegions()

PiCameraRegions robotCore.PiCamera.getRegions

(

)

Returns the latest set of camera regions. Note that the data is received from the camera in a separate thread so calling this twice in a row can generate a different result. Once you retrieve and instance of PiCameraRegions however, you can be assured that it will NOT be modified when a new frame is received.

getStats()

PiCameraStats robotCore.PiCamera.getStats

(

)

Returns the current camera performance stats

isConnected()

boolean robotCore.PiCamera.isConnected

(

)

Returns true if connected to the camera

setLight()

void robotCore.PiCamera.setLight

(

int

value

)

if the Raspberry Pi is configured to controll the camera lights using pins 11 and 12, this command will turn the lights on or off

Parameters

value

- Bit zero controls pin 11 and bit one controls pin 12

setProfile()

void robotCore.PiCamera.setProfile

(

int

profile

)

Specifies which capture profile should be used.

Parameters

profile

- Specifies the profile to use (0-3)

startLogging()

void robotCore.PiCamera.startLogging

(

String

path

)

Starts logging the data received from the Raspberry Pi locally

Parameters

path	- Specifies the path for the log file.

startPiLog()

void robotCore.PiCamera.startPiLog

(

)

Instructs the Raspberry Pi to start logging the camera data on the Pi's disk This can be useful for debugging
