Modes of Operation
Mode 1:
Temperature monitoring by comparing
a precision input temperature sensor
and a reference temperature
sensor. The 8-bit ADC data of the
input temperature is displayed in an
8-bit LED display. If the input
temperature is higher than the
reference temperature, the buzzer will
be triggered.
Mode 2:
Temperature monitoring simulation
using a potentiometer and a reference
temperature sensor. The 8-bit ADC
data of the potentiometer is displayed
in an 8-bit LED display. The
potentiometer is adjustable from 0 V
to 5 V, which acts as an input to be
compared with the reference
temperature. If the input voltage is
higher than the ADC voltage of the
reference temperature, the buzzer will
be triggered.
Mode 3:
Generating an incremental counter
signal, a slow varying sawtooth signal
with approximately 0.8 Hz to 48 Hz
(adjustable using a potentiometer).
The Digital-to-Analog Converter (DAC)
yields an output voltage of 256 levels
between 0 V to 4.98 V, see Figure 1.

Mode 4:
Generating a 5 V triangular wave with
approximately 0.4 Hz to 48 Hz
(adjustable using potentiometer), see
Figure 2.

Mode 5:
Generating a 1.6 V square wave with
approximately 52 Hz to 7 kHz
(adjustable using a potentiometer),
see Figure 3.

Mode 6:
Generating a 5 V irregular pulse wave
with period of approximately 0.4 Hz to
48 Hz and a total width of 2.6 ms to
300 ms (adjustable using a
potentiometer), see Figure 4.

Mode 7:
Generating a 5 V sinusoidal wave with
approximately 0.4 Hz to 48 Hz
(adjustable using a potentiometer),
see Figure 5.

Mode 8:
Generating a mixed sinusoidal signal
with digital noise, see Figure 6. The
maximum achievable frequencies are
approximately 4.2 kHz and 6.2 kHz.
The digital noise can be fi ltered using
digital scope fi ltering.
