Writing to Registers
The TMP103EVM software contains two different methods for writing data:
Write All Reg
and
Auto-Write
Reg
. Individually writing the registers without Auto-Write can be useful when adjusting large numbers of
the configuration registers on the left. Also, if the user wishes to change some of the configuration settings
on the left while continuously reading registers, he or she will be prompted with a blinking
Write All
Registers
button. Until the
Write All Registers
button has been selected, the program stops polling data
from the TMP103 sensors. Conversely, the
Auto-Write Registers
feature automatically makes changes to
the configuration register whenever one of the configuration settings on the left changes, as indicated in
Figure 17
.

Conversion Time
The
Conversion Time
selection box, shown in
Figure 18
, is used to change the speed at which the
TMP103 sensors measure the ambient temperature around them. A user may want to set the conversion
speed faster if data must be gathered faster. The user should be aware that increasing the conversion
speed also increases the power consumed by the devices. While this increase in power consumption may
not cause any issues for the TMP103EVM, users may want to reduce power consumption on certain
applications or custom boards. Users should be cautious of this feature.
