Figure 7.1. Acconeer Software offer.

RSS (Radar System Software) provides an API for controlling and retrieving data from the sensor. The

data output can be on two different levels, Service and Detector.

Service output is radar data with some pre-processing.

Detector output is based on Service output but uses further processing to create a result such as a

distance or presence detection.

Customer can either use Acconeer detector or develop their own signal processing based on Service

data.

Acconeer provides several example applications to support customer own application development.

Also, guidelines are provided for application development utilizing the Acconeer RSS API.

Integration software shall implement functions defined in a definitions file provided in Acconeer

Software offer. This includes handling of SPI, ENABLE, INTERRUPT and CTRL, as well as

potential OS functions.

See reference A121 User Guide HAL Software Integration for guideline on software integration and

HAL implementation (https://www.acconeer.com/products).

Acconeer provides reference integrations as source code.
