/* Hamshield
|
|
* Example: Serial Tranceiver
|
|
* SerialTransceiver is TTL Serial port "glue" to allow
|
|
* desktop or laptop control of the HamShield.
|
|
* 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. Use the bar at the
|
|
* top of the serial monitor to enter commands as seen below.
|
|
*
|
|
* EXAMPLE: To change the repeater offset to 144.425MHz,
|
|
* enable offset, then key in, use the following commands:
|
|
* T144425;
|
|
* R1;
|
|
* [Just a space]
|
|
|

Mode ASCII Description Implemented

|
-------------- ----------- -------------------------------------------------------------------------------------------------------------------------------------------- -----------------
|
|
Transmit space Space must be received at least every 500 mS Yes
|
|
Receive not space If space is not received and/or 500 mS timeout of space occurs, unit will go into receive mode Yes
|
|
Bandwidth E<mode>; for 12.5KHz mode is 0, for 25KHz, mode is 1 No
|
|
Frequency F<freq>; Set the receive frequency in KHz, if offset is disabled, this is the transmit frequency No
|
|
Morse Out M<text>; A small buffer for morse code (32 chars)
|
|
Power level P<level>; Set the power amp level, 0 = lowest, 15 = highest No
|
|
Enable Offset R<state>; 1 turns on repeater offset mode, 0 turns off repeater offset mode No
|
|
Squelch S<level>; Set the squelch level No
|
|
TX Offset T<freq>; The absolute frequency of the repeater offset to transmit on in KHz No
|
|
RSSI ?; Respond with the current receive level in - dBm (no sign provided on numerical response) No
|
|
Voice Level ^; Respond with the current voice level (VSSI)

------------ ---------- -----------------------------------------------------------------
|
|
Startup *<code>; Startup and shield connection status
|
|
Success !; Generic success message for command that returns no value
|
|
Error X<code>; Indicates an error code. The numerical value is the type of error
|
|
Value :<value>; In response to a query
|
|
Status #<value>; Unsolicited status message
