Remote User Interface (RUI)
The RUI module is depicted in Figure 7. The module is
defined in the rui_view files and it utilizes the rui_thread and
interfaces files to carry out its operations. The interfaces
files in turn utilize the can , i2c , spi , tcp_server , and uart files.
The most important operations contained in these files are as
follows:
•
rui_view:
Defines the resources needed for the RUI,
most importantly the interfaces object.
•
rui_thread: Defines the RUI thread that is spawned to
offload the intense process of listening for commands,
processing them, and sending back responses from the
GUI thread.
•
interfaces: Defines the generic interface that is used to
connect SensorRF − GEVK to an external device either
through the UART, TCP, CAN, SPI or I
2
C interfaces.
•
can:
Defines the CAN Linux socket.
•
i2c:
Defines the I
2
C Linux socket.
•
spi: Defines the SPI Linux socket.
•
tcp_server: Defines the TCP Server Linux socket.
•
uart: Defines the UART Linux socket.

Model
The Model module is depicted in Figure 8. The module is
defined in the kit_model files and it utilizes the sensorTag ,
GPIO , util , and utility files to carry out its operations. Some
of the most important system operations are contained in
these files and are as follows:
•
kit_model: Defines the resources needed for the
Model, most importantly the reader object, the
sensorTag lists, and the functions available to set the
Reader settings and perform reads. The most important
operations
available in the Model will be described
below.
•
sensorTag: Defines the data structures used to store
sensor reads, sensor measurements, and sensor data.
•
GPIO:
Defines the object through which the
BeagleBone’s GPIOs can be accessed, which is used to
turn the Reader on/off and to connect the UART, I
2
C or
SPI ports on the board to the BeagleBone when one of
those interfaces is selected.
•
util: Defines helper functions for GPIO.
•
utility: Defines helper functions for performing data
conversions.
