I have brought two MSP-EXP430FG4618 evl boards .
Since these boards provides the mic and audio jack , I want to implement my audio based project on this ..
my main goal is to generate some signal at 22kHz and transmit. At the other end I should receive the signal and verify the frequency and signal .
If I want to implement this , will this mic ( present on the EV ) is enough to record the 22kHz signal and what kind of speaker I need to connect at the audio jacks , The maximum range(b/w tx and rx) I would require is 5 to 6m ..
