MEASUREMENTS TAB
This view contains all the values related to the temperature channels, fan parameters
and status of the device features.
FIGURE 3-14:
Temperature Sensor View –
Measurements
Tab.
The
Measurements
tab provides an overview of all the temperature, fan speed and
state-related readings from the EMC2103-4 device:
• The temperature values are presented in both the Temperature table (marked in
with (
1
) and in the Data Acquisition chart (
6
). The chart can be
configured to display any combination of the device channels by enabling the
corresponding channel checkbox from the Plot Options section.
• The temperature channels’ status is displayed in the Status section (marked in
with (
2
), where a green icon represents normal operation and a red
icon signals that the limit or the Fault condition named on the row title has been
reached.
• The fan values are displayed in the Fan section (
3
) and the RPM value can also
be presented in the Data Acquisition chart. The fan driver output voltage is
measured using the MCP2221A ADC and calculated using the following formula:
(first channel for ADC) * 2(mV per bit)/1000 * 11(voltage divider)
• The device’s status is displayed in the Status section (
4
), where a green icon rep-
resents normal operation (limit not exceeded, no Fault condition) and a red icon
signals that a limit has been reached or a Fault condition has been detected.
• The GPIO and Interrupt states are monitored in the section marked by (
5
) in
. The GPIO Input/Output section monitors the pin direction of each
GPIO pin. The GPIO States section indicates the state of the corresponding GPIO
pin. The Interrupt Status reports the operating condition of the device. The
TRIP_SET Voltage register value is displayed. This value is proportional to the
TRIP_SET Resistor value.
• The device data can be read continuously by clicking the
Start
button from the
toolbar or manually sampled by clicking the
Update Registers
button. The chart
is only updated during continuous sampling.
