Description
This user guide describes an evaluation kit and the extension boards for a SIGFOX
application. This application uses an Atmel ATmega328P AVR microcontroller to
read out an AT30TS75A temperature sensor using the built-in TWI connection and controls
the RF telegram transmission using the SIGFOX ATA8520D V1.3 transceiver device. This
application requires a SIGFOX base station infrastructure to capture the RF telegram and
supply payload data at the SIGFOX back end of the SIGFOX Cloud. For more information
on operating the SIGFOX network and SIGFOX Cloud, see
information.
The evaluation and development kit tool packs are available for download from the Atmel
website: http://www.atmel.com/devices/ATA8520.aspx. These tool packs include
●
The ATAN0054 quick start guide for the kit and the Atmel ATAN0104 user guide
●
The schematic, layout and Gerber data for the ATAB0101A PCB
●
The source code for the Atmel ATmega328P as an Atmel Studio 6 project
The Atmel ATA8520D SIGFOX transceiver is a SIGFOX-certified device which includes the
complete SIGFOX protocol stack to operate in the SIGFOX network within the 868MHz
ISM band. The device is controlled from any host MCU using the SPI commands as
described in the datasheet [1]. Included in the tool pack is a ATA8520D library as C source
code for the SPI commands.
