During the time this program records the frequency, the Debug Terminal display is
similar to the previous revision of the program. When the program is done recording, it
displays ten frequency samples. The Debug Terminal data shown in Figure 6-10 was
generated by adjusting the pot back and forth to some random frequencies (tones).
About the Code
Program Listing 6.2 Revision 2 introduces the concept of data storage using an array.
We used the command:
to reserve 10 words of space in the BASIC Stamp's RAM. There's a word labeled f(0),
another word labeled f(1), and so on through f(9). Each of these words is stored adjacent
to each other in the BASIC Stamp's RAM.
