AS7261 − Detailed Descriptions

Figure 30:

UART Protocol

AT Command Interface

The microprocessor interface to control the AS7261 is via the

UART, using AT Commands across the UART interface. This AT

Command interface 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

between the network interface and the core of the system,

provides access to the AS7261’s Cognitive Light Engine’s control

and configuration functions.
