Figure 5-1: Logic Analyzer Application
This PC-based application is used to display the logic analyzer data on the
PC. The logic analyzer data is displayed in real-time and each waveform may
be paused, zoomed, and printed.
If the microcontroller-based Quick Start Application is programmed into the
MCU, the IN0 channel will show the emulated PTC0 signal to have the same
output as the PWM signal at port PTB5 (driving the Buzzer). The IN1 channel
will show the PWM period waveform on channel PTC1.
Step 1.
Step 2.
Step 3.
Step 4.
Press the button labeled “PTA2.” The PTC0 pin will output a fixed
75% duty cycle pulse width modulation (PWM) signal. The Buzzer
sound is also turned on.
Press the PTA2 button a second time. The PTC0 PWM duty cycle
will change to 25%. The Buzzer remains on.
Press the PTA2 button a third time. The duty cycle is controlled by
the potentiometer (W1). The illumination of LED PTC0 and the
tone of the Buzzer will vary as you rotate the potentiometer.
Press PTA2 a fourth time, or press button PTA3 at any time, to turn
off the Buzzer and all LEDs.
This PC-based application is included on the DVD-ROM that accompanies
the DEMOQE, and may also be found at:
