This module provides a simple interface to TCS34725 colour/light sensors (Adafruit).

!!! Warning

You must call [`setup()`](#tcs34725setup) before you can start reading values!

tcs34725.setup()

Initialization via this call is mandatory before values can be read.

tcs34725.setup()

0 if setup has failed (no sensor connected?), 1 if sensor is TCS34725

lua

tcs34725.setup()
tcs34725.enable(function()
	print("TCS34275 Enabled")
	clear,red,green,blue=tcs34725.raw()
end)

Enables the sensor. Can be used to wake up after a disable.

lua

tcs34725.enable(function()
	print("TCS34275 Enabled")
	clear,red,green,blue=tcs34725.raw()
end)

A function called when the sensor has finished initialising.

Disables the sensor. Enables a low-power sleep mode.

tcs34725.disable()

Reads the clear, red, green and blue values from the sensor.

clear,red,green,blue=tcs34725.raw()

clear, red, green, blue in uint16_t.

Sets the gain of the sensor. Must be called after the sensor is enabled.

tcs34725.setGain(gain)

Sets the integration time of the sensor. Must be called after the sensor is enabled.

tcs34725.setIntegrationTime(time)
