Acconeer also provides detectors, such as a distance detector where the application can push service
data to retrieve data result.
7.2 Devices and Drivers
The driver for SPI and INTERRUPT shall implement the defined functions found in the corresponding
device header file, acc_device_spi.h and acc_device_gpio.h. Registration of these functions shall be
done in the acc_board_init function, see chapter 7.3 for details.
7.3 Board File Interface and Implementation
The board header file, acc_board.h is the board file interface. Contents may not be changed,
implementation needed for all functions and parameters in the file. NOTE, an implementation may in
some cases be empty.
A detailed description of each board file function is shown in the table below.
