Temperature sensor features

The steps for starting with the temperature sensor daughter cards and the GUI are as

follows:

Place the temperature sensor daughter card on the motherboard. Take note of the

notch on the daughter card connector and motherboard connector.

Select the power supply of the daughter card as mentioned in Section 1.2.3.

Connect the USB cable to the computer and motherboard, LED D3 glows on the

motherboard.

Open the GUI in the computer, the GUI window shows as connected in the bottom right

corner, as shown in Figure 2.

Press the “Temperature Sensor Mode Select” button in the GUI, as shown in Figure 2.

The list of temperature sensors appears in the GUI, as shown in Figure 4. Select the

sensor which is mounted on the motherboard. If the sensor selected in the GUI is not

the one mounted on the motherboard, an error message pops up in the GUI. In the

case of an error message, re-select the correct sensor in the GUI.

The GUI window for the sensor present on the motherboard opens.

A total of 5 sensors are supported by the demo:

●

STTS7/STDS75/STLM75/STCN75

●

STTS424E02
