The ADS1x15 device also contains an internal comparator. The threshold limits for the comparator are set using
the
HiThresh
and
LoThresh
registers.
5.2.3.1 Register Read and Write Options
At the top and right side of the
Register Map
) are controls for reading and
writing the registers. The startup default control values are to
Immediately Write
the
Config
register when options
change. The
Auto Read
register function is turned off.
Figure 5-23. Register Read and Write Controls
5.2.3.1.1 Read Register Options
The default GUI configuration is to have the
Auto Read
functionality turned off and instead manually read the
registers using the
READ REGISTER
and
READ ALL REGISTERS
buttons. The
READ REGISTER
button reads
only the selected register. The
READ ALL REGISTERS
button reads all registers available for the ADS1x15
device. The advantage of manually reading the register contents is a reduction in USB communication between
the ADS1x15EVM and the GUI.
The registers can be read automatically from the ADS1x15 at a variety of intervals from once a second to as fast
as possible. The
Auto Read
drop-down menu selection (
) shows these intervals, which can each be
selected based on the application needs. The
READ REGISTER
and
READ ALL REGISTER
button options are
only enabled when the
Auto Read
selection is turned
off
.
