AS7263 − Detailed Description

Figure 31:

UART Protocol

AT Command Interface

The microprocessor interface to control the NIR Spectral_ID

Sensor is via the UART, using the AT Commands across the UART

interface.

The 6-channel Spectral _ID sensor provides a text-based serial

command interface borrowed from the “AT Command” model

used in early Hayes modems.

For example:

• Read DATA value: ATDATA

→ <data>OK

• Set the gain of the sensor to 1x: ATGAIN =0

→ OK

The “AT Command Interface Block Diagram”, shown below be-

tween the network interface and the core of the system, pro-

vides access to the Spectral_ID engine’s control and configura-

tion functions.
