ams TCS3472 Color Sensor

Datasheets

Description

The TCS3472 device provides a digital return of red, green, blue (RGB), and clear light sensing values. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately (16 Bit each color).

Usage

The sensor will be initialized through the BSP. These default values will be set:

  • Integration time to 2.4ms

  • Gain to 1x

The initialization starts the first conversion with the given parameters. If those are suitable, the sensor data can be used as shown in the example.

// Read the 16 bit converted color values and start a new conversion
RGBA16 color = yggdrasil_ColorSensor_GetColor16(true);
printf("Color RGBA16: %d, %d, %d, %d \n", color.r, color.g, color.b, color.a);

When the Integration time and the gain must be changed, a new conversion must be started.

// Wait until the sensor is not working
while (!yggdrasil_ColorSensor_IsDone());

// Set a new integration time
yggdrasil_ColorSensor_SetIntegrationTime(ColorSensorIntegrationTime_10ms);

// Set a new gain
yggdrasil_ColorSensor_SetGain(ColorSensorGain_4x);

// Start a new conversion
yggdrasil_ColorSensor_StartConversion();
