8 Software

The Acconeer software has been written in C and is portable to any OS and HW platform. The

Acconeer software is executed on Host MCU and delivered as binaries, except for integration software

that is delivered as source code.

The below figure shows the A121 software offer.

Figure 8.1. Acconeer Software offer.

The RSS (Radar System Software) provides output at two different levels, Service and Detector. RSS

provides an API (Application Programming Interface) for Application utilization of various Services

and Detectors.

The SparseIQ service output is pre-processed sensor data as a function of IQ modulated data

(representation in cartesian) etc.

Detectors are built on SparseIQ Service data as input and the output is a result, e.g. Distance detector

that presents distance and amplitude result based on envelope Service etc.

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

Service data.

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

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

Acconeer provides several reference drivers as source code, e.g. Support for Cortex M4, Cortex M7

MCU’s.

8.1 Software Integration

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.
