GUI window for STTS75, STDS75, STLM75 and STCN75 sensors
The STTS75, STLM75, STDS75, and STCN75 sensors are supported by a single GUI
window, as shown in
window, as shown in
. There are radio buttons for selecting one of four possible
sensors (STTS75, STLM75, STDS75, and STCN75).
Below are the steps for operating these sensors using the GUI:
1.
Select one of the radio buttons present in the “Select the temperature sensor” area in
the GUI. This enables the GUI for one of the selected sensors
(STTS75/STLM75/STDS75/STCN75).
the GUI. This enables the GUI for one of the selected sensors
(STTS75/STLM75/STDS75/STCN75).
2.
Choose the address from the dropdown menu of the “Choose Address” block. If the
address selected from the GUI is the same as configured onboard (as described in
address selected from the GUI is the same as configured onboard (as described in
), the remaining part of the GUI is enabled; or else an error message
appears in the GUI, as shown in
. In the case of an error message, check the
correct address from the GUI.
3.
Configure the different registers of the sensor and observe the behavior in the GUI and
on the board. The bits of the configuration register can be selected in the GUI and can
be written by pressing the ‘Write’ button.

be written by pressing the ‘Write’ button.
4.
The slider for over-limit and hysteresis can be used to select the values for
oversaturation and hysteresis registers of the sensor.
oversaturation and hysteresis registers of the sensor.
5.
The “Once” button is used to read the instantaneous value of the temperature value
from the sensor.
from the sensor.
6.
The “Loop” button is used to continuously read the temperature value from the sensor
and display the same in the GUI.
and display the same in the GUI.
7.
ALARMS is seen in the GUI only when the Once or Loop button is pressed. Pressing
Once reads the instantaneous temperature value and latches the instantaneous
ALARM condition in the GUI. Pressing the Loop button continuously monitors the
temperature and the ALARM condition and displays the same in the GUI. Stopping the
Loop button latches the last measured value of temperature and the last ALARM
condition in the GUI. This alarm is used to indicate the behavior of the OS pin output of
the temperature sensor.
