Lab 8: DTMF Decoder Part 3: Detection of Eight Frequencies
Expand Lab 8 to determine which DTMF signal is present. Use a DSP board
running your program from Lab 4 to generate a DTMF signal. Use that signal as
an input to a DSP board running your program from this lab. You should have
16 outputs on Port B indicating which of the 16 DTMF tones is present.
