Detailed Description

TCS34725 control class.

Example: 

 //Send rgb data to the serial port
 #include "TCS34725.h"
 #include "mbed.h"

 TCS34725 colorSens(p9, p10); //I2C sda and scl
 Serial pc(USBTX, USBRX); //USB serial

 int main() {
   uint16_t r,g,b,c;
       
   if(!colorSens.init(TCS34725_INTEGRATIONTIME_101MS, TCS34725_GAIN_60X)){
       pc.printf("ERROR\n"); //check to see if i2c is responding
   }

   while(1) {
        colorSens.getColor(r,g,b,c); //pass variables by reference...
      pc.printf("DATA: r%d g%d b%d c%d", r, g, b, c);
      wait(0.5);
  }
 }

Constructor & Destructor Documentation

TCS34725 (  )

Initialize object with default i2c pins.

Definition at line 3 of file TCS34725.cpp.

TCS34725 ( PinName  i2c_sda,
PinName  i2c_scl 
)

Initialize object with specific i2c pins.

Parameters:
i2c_sdaSDA pin
i2c_sclSCL pin

Definition at line 4 of file TCS34725.cpp.

Member Function Documentation

void config ( char  intTime,
char  gain 
)

Configure after initial boot (will restart sensor)

Parameters:
intTimeIntegration time for reading (will delay accordingly)
i2c_sclGain value
Returns:
1 if failed ` 0 if successful

Definition at line 44 of file TCS34725.cpp.

void DEBUG ( Serial *  deb )

Debug function...

probably not useful unless youre debugging your i2c line

Parameters:
debSerial object for debugging (passed by reference)

Definition at line 77 of file TCS34725.cpp.

void getColor ( uint16_t &  r,
uint16_t &  g,
uint16_t &  b,
uint16_t &  c 
)

Returns rgbc reading from the sensor.

Parameters:
rRed value (passed by reference)
gGreen value (passed by reference)
bBlue value (passed by reference)
cClear value (all wavelengths - essentially shade) (passed by reference)

Definition at line 50 of file TCS34725.cpp.

bool init ( char  intTime,
char  gain 
)

Boot up the sensor and checks if acking (see header for param defines)

Parameters:
intTimeIntegration time for reading (will delay accordingly)
i2c_sclGain value

Definition at line 28 of file TCS34725.cpp.
