/* Hamshield
|
|
* Example: KISS
|
|
* This is a example configures the HamShield to be used as
|
|
* a TNC/KISS device. You will need a KISS device to input
|
|
* commands to the HamShield
|
|
* 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. Issue commands
|
|
* via the KISS equipment.
|
|
*
|
|
* To use the KISS example with YAAC:
|
|
* 1. open the configure YAAC wizard
|
|
* 2. follow the prompts and enter in your details until you get to the "Add and Configure Interfaces" window
|
|
* 3. Choose "Add Serial KISS TNC Port"
|
|
* 4. Choose the COM port for your Arduino
|
|
* 5. set baud rate to 9600 (default)
|
|
* 6. set it to KISS-only: with no command to enter KISS mode (just leave the box empty)
|
|
* 7. Use APRS protocol (default)
|
|
* 8. hit the next button and follow directions to finish configuration
