Class TCS34725ColorSensor

java.lang.Object

org.usfirst.frc.team1736.lib.Sensors.TCS34725ColorSensor

public class TCS34725ColorSensor
extends java.lang.Object

DESCRIPTION:
Simple API for the TCS34725 color sensor from adafruit Provides interfacing for initializing the sensor and performing qualified reads of color values. Coded with lots and lots of help from https://github.com/adafruit/Adafruit_TCS34725. Thanks KTOWN!!! If I ever meet you at a non-FRC event, I owe you a drink.
USAGE:

1. Instantiate class.
2. Call init() once to set up the sensor
3. Once per periodic loop, call the readColors() method to get data from the sensor.
4. After the readColors() call, use the getCOLOR() methods to access the most recent color readings (RGBC) from the sensor.

Field Summary

Fields

Modifier and Type	Field and Description
boolean	good_data_read True if the last read from the sensor was good, bad if data was corrupted
boolean	sensor_initalized True if sensor has been initialized, false if not

Method Summary

Modifier and Type	Method and Description
int	getBlueVal() Returns the most recent blue intensity read from the sensor
int	getClearVal() Returns the most recent overall intensity read from the sensor
int	getGreenVal() Returns the most recent green intensity read from the sensor
int	getRedVal() Returns the most recent red intensity read from the sensor
int	init() Initializes the actual sensor state so colors can be read.
int	readColors() Queries the sensor for the red, green, blue, and clear values Qualifies the read to ensure the sensor has not been reset since the last read.

Field Detail

sensor_initalized

public boolean sensor_initalized

True if sensor has been initialized, false if not

good_data_read

public boolean good_data_read

True if the last read from the sensor was good, bad if data was corrupted

Method Detail

init

public int init()

Initializes the actual sensor state so colors can be read. By default the sensor powers up to a "disabled" state. This enables it. Additionally, checks the sensor has the proper internal ID and sets hard-coded gains and integrator times.

Returns:

0 on success, -1 on failure to initialize

readColors

public int readColors()

Queries the sensor for the red, green, blue, and clear values Qualifies the read to ensure the sensor has not been reset since the last read.

Returns:

0 on read success, -1 on failure.

getRedVal

public int getRedVal()

Returns the most recent red intensity read from the sensor

Returns:

most recently read red intensity

getGreenVal

public int getGreenVal()

Returns the most recent green intensity read from the sensor

Returns:

most recently read green intensity

getBlueVal

public int getBlueVal()

Returns the most recent blue intensity read from the sensor

Returns:

most recently read blue intensity

getClearVal

public int getClearVal()

Returns the most recent overall intensity read from the sensor

Returns:

most recently read overall intensity
