SerialCommunication

The Pmod COLOR communicates with the host board via the I²C protocol. By first sending the 7-bit

I²C device address of 0101001 (0x29), users may receive the color data from the TCS3472. Each of

the four ADC channels (red, green, blue, and clear) sends it's conversion from the ADC to the host

buffer simultaneously.

The TCS3472 can set the gain and integration time for each round of data collection. Integration

time provides more time for the color sensor to collect more data, providing accurate data and

helping to prevent the data from disproportionately capturing any overexposure that may occur.

Each set of the 16-bit data is organized in a low-byte, high-byte arrangement.

DataRegisters

Each of the three colors (RGB) and the clear color byte has two registers to store the high and low

data bytes for each measurement. The data registers are arranged in a low byte, high byte

arrangement.
