To view the mid, and low frequency output sine waves, perform the following
steps:
- Cycle the sine wave sequential circuit by pressing the GPIO_SW_E push button
as shown in the following figure.
- Click Run Trigger Immediately again to
see the new sine selected sine wave. You should see the mid frequency as shown
in the following figure. Notice that the
sel
signal also changed from 0 to 1 as expected.
- Repeat step 1 and 2 to view other sine wave outputs.
Note: As you sequence through the sine wave selections, you may notice that the LEDs do not light up in the expected order. You will debug this in the next section of this tutorial. For now, verify for each LED selection, that the correct sine wave displays. Also, note that the signals in the Waveform window have been re-arranged in the previous three figures.
