Description/Parameters

Spectral Data per Channel

ATDATA

<V_value>,

<B_value>,

<G_value>,

<Y_value>,

<O_value>,

<R_value> OK

Read V, B, G, Y, O & R data. Returns comma-separated

16-bit integers.

ATCDATA

<Cal_V_value>,

<Cal_B_value>,

<Cal_G_value>,

<Cal_Y_value>,

<Cal_O_value>,

<Cal_R_value> OK

Read calibrated V, B, G, Y, O & R data. Returns

comma-separated 32-bit floating point values.

Sensor Configuration

ATINTTIME=<value>OK

Set sensor integration time. Values should be in the range

[1..255], with integration time = <value> * 2.8ms.

ATINTTIME

<value> OK

Read sensor integration time, with

integration time = <value> * 2.8ms

ATGAIN=<value>

Set sensor gain: 0=1x, 1=3.7x, 2=16x, 3=64x

ATGAIN

<value>OK

Read sensor gain setting, returning 0, 1, 2, or 3 as defined

immediately above.

ATTEMP

<value>OK

Read temperature of chip in degree Celsius.

ATTCSMD=<value>

Set Sensor Mode

0 = BANK Mode 0;

1 = BANK Mode 1;

2 = BANK Mode 2;

3 = BANK Mode 3 One-Shot;

4 = Sensors OFF

In One-Shot mode, each ATTCSMD=3 command triggers a

One-Shot reading

ATTCSMD

<value> OK

Read Sensor Mode, see above.

ATBURST=<value>

<value>= # of samples

(ATBURST=1 means run until ATBURST=0 is received (a

special case for continuous output).
