1 opensensor - information material version 1.0Aalborg University, Mobile Device Group opensensor Part 4 Opensensor details Frank H.P. Fitzek Anders Grauballe Gian Paolo Perrucci Ben Kroeger Aalborg University Stephan Rein Technical University of Berlin

2 opensensor - information materialAalborg University, Mobile Device Group Fitzek/Rein/Grauballe/Perrucci/KroegerAalborg University and Technical University of Berlin overview Opensensor specification Opensensor functionality •Timer •Digital/analog ports •UART •SPI - nRF Opensensor interfaces •Serial interface –Opensensor debug and test •SPI (nRF905) interface •Bluetooth interface (next time)

3 opensensor - information materialAalborg University, Mobile Device Group Fitzek/Rein/Grauballe/Perrucci/KroegerAalborg University and Technical University of Berlin opensensor details •Opensensor specification –Microchip dsPIC30f3013 processor –16 bit architecture –C compiler optimized instruction set –24KB program memory –2KB RAM –20 I/O pins –2 UART interfaces –SPI interface –Timers 3 x 16-bit 1 x 32-bit –Red and Green LED –Low power consumption

4 opensensor - information materialAalborg University, Mobile Device Group Fitzek/Rein/Grauballe/Perrucci/KroegerAalborg University and Technical University of Berlin opensensor details •Timers can be used for –Timing –Timeouts –Sleep functions –Pulse-width modulation PWM –Etc. •Digital analog ports –Most ports can be configured to either input or output –Measurements of environmental conditions –Controller for third party systems e.g. home control systems

5 opensensor - information materialAalborg University, Mobile Device Group Fitzek/Rein/Grauballe/Perrucci/KroegerAalborg University and Technical University of Berlin opensensor details •UART –Standard RS232 interface –Bluetooth interface

6 opensensor - information materialAalborg University, Mobile Device Group Fitzek/Rein/Grauballe/Perrucci/KroegerAalborg University and Technical University of Berlin opensensor details •Open sensor interfaces –Serial interface for wired connection with a PC –Easy debugging while programming –Implements command interface for the opensensor –Can be accessed via a terminal program e.g. Hyper Terminal, Cutecom etc. –Program is provided on the website as well as instructions on how to use it

7 opensensor - information materialAalborg University, Mobile Device Group Fitzek/Rein/Grauballe/Perrucci/KroegerAalborg University and Technical University of Berlin opensensor details •SPI – nRF905 –Operating frequencies: 433/868 or 915MHz –Gaussian frequency shift keying –Power settings •Output power: -10dBm, -2dBm, 6dBm or 10dBm •RX reduced power mode -85dBm –Carrier detect –Address match –Auto retransmit

8 opensensor - information materialAalborg University, Mobile Device Group Fitzek/Rein/Grauballe/Perrucci/KroegerAalborg University and Technical University of Berlin opensensor details •Opensensor interfaces –SPI interface with the nRF905 chip to establish communication between more opensonsers –MAC protocol can be implemented –Low power consumption and cost
