AS7261 − Detailed Descriptions

Sensor Configuration

ATINTTIME=<value>OK

Set sensor integration time. Values should be in the range

[1... 255], with

integration time = <value> * 2.8msecs.

ATINTTIME

<value> OK

Read sensor integration time, with

integration time = <value> * 2.8msecs.

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 Celsius

ATTCSMD=<value>

Set Chromatic White Color Sensor Mode

0  Captures X, Y, Z, and IR (1 integration period)

1  Captures X, Y, Dk, and CLR (1 integration period)

2  Captures X, Y, Z, Dk, IR and CLR

(2 integration period)

3  Sensors are OFF

ATTCSMD

<value> OK

Read Color Sensor Mode, see above

ATINTRVL=<value>

Set the sampling interval as an integer multiple of the

Integration time. The <value> is an integer between

[1..255].

A sampling interval=1 implies a sampling rate of 1x the

current integration time.

A sampling interval=255 implies a slow sampling rate of

255 times the current integration time.

ATINTRVL

<value>OK

Read the sampling interval as an integer multiple of the

Integration time.

Returns an integer in the range [1..255] as defined above

ATBURST=<value>.

<value>= # of samples

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

special case for continuous output)

LED Driver Controls

ATLED0=<value>

Sets LED_IND: 100=ON, 0=OFF

ATLED0

<100|0>OK

Reads LED_IND setting: 100=ON, 0=OFF

ATLED1=<value>

Sets LED_DRV: 100=ON, 0=OFF

ATLED1

<100|0>OK

Reads LED_DRV setting: 100=ON, 0=OFF

ATLEDC=<value>

Sets LED_IND and LED_DRV current

LED_IND: bits 3:0; LED_DRV: 7:4 bits

LED_IND: ‘b00=1mA; ‘b01=2mA; ‘b10=4mA; ‘b11=8mA

LED_DRV: ‘b00=12.5mA; ‘b01=25mA; ‘b10=50mA;

‘b11=100mA

ATLEDC

<value>OK

Reads LED_IND and LED_DRV current settings as shown

above
