AS7265x − Detailed Description

Figure 57:

UART Protocol

AT Command Interface

The microprocessor interface to control the AS72651 Spectral_

ID sensor(s) is via AT Commands across the UART interface. The

AS72651 provides a text-based serial command interface bor-

rowed from the “AT Command” model used in early Hayes mo-

dems.

For example:

The AT Command Interface, shown below provides access to

the Spectral_ID engine’s control and configuration functions.
