The differential amplifier outputs are connected to the ADC input. The digitally converted current
samples are sent to PC through the UART-to-USB IC (U12). Finally, the measured current is
presented to the PC converter and displayed in the power profiler of SmartSnippet Toolbox.

8.2 Power Profiler of Smartsnippet Toolbox
Dialog’s SmartSnippets Toolbox can be invoked from within the SmartSnippets Studio Welcome
page.
Alternately, it can run directly from the start menu under the section “
Dialog SmartSnippets Studio
vx.x.xx\Dialog SmartSnippets Toolbox for SmartSnippets Studio vx.x.xx
”.
Upon opening, the application starts with the settings/interface options page. An existing entry can be
selected from the list, or a new configuration can be created by pressing the
“
New
” button (
Figure
38 ).
At this point, to change the hardware setup, for example, to plug in another board, by pressing the
“
Refresh
” button (
Figure 38 ), the list of available ports will be updated.
To select the chip version, when
the “
Detect
” button (
Figure 38 ) is pressed, the tool identifies the
exact part number of the SoC on the target board
For power measurements, users need to select an interface that allows the PC software
(SmartSnippets Toolbox) to communicate with the A/D converter through the correct SPI port (which
is camouflaged in the PC as a plain UART part. In
Figure 38 , the selected SPI port is COM18).
For power measurement, the
“
UART/SPI
” option in
Figure 38 is preferred, because JTAG is used for
downloading code from the IDE and debugging. The
“
Hybrid
” option can also be used. But power
measurements are not feasible in the
“
UART-only
” or “
JTAG
” option.
