* Example: AFSK Packet Tester
|

* This example sends AFSK test data. You will need a seperate
|
|
||||||
* AFSK receiver to test the output of this example.
|
|
||||||
* Connect the HamShield to your Arduino. Screw the antenna
|
|
||||||
* into the HamShield RF jack. Connect the Arduino to wall
|
|
||||||
* power and then to your computer via USB. After uploading
|
|
||||||
* this program to your Arduino, open the Serial Monitor to
|
|
||||||
* monitor the process of the HamShield. Check for output on
|
|
||||||
* AFSK receiver.
|
|
||||||
|
|
||||||
* Note: add message receive code

/* Hamshield

* This example prints Signal, Audio In, and Audio Rx ADC
|

* Peak strength to the Serial Monitor in a graphical manner.
|
|
||||||
* Connect the HamShield to your Arduino. Screw the antenna
|
|
||||||
* into the HamShield RF jack. Plug a pair of headphones into
|
|
||||||
* the HamShield. Connect the Arduino to wall power and then
|
|
||||||
* to your computer via USB. After uploading this program to
|
|
||||||
* your Arduino, open the Serial Monitor. You will see a
|
|

* repeating display of different signal strengths. Ex:
|
|
||||||
*
|
|
||||||
* [....|....] -73

* Signal

* Uncheck the "Autoscroll" box at the bottom of the Serial

* Monitor to manually control the view of the Serial Monitor.
