/* Hamshield
|
||||||
|
* Example: AppSerialController_nRF52840
|
||||||
|
* This is a simple example to demonstrate the HamShield working
|
||||||
|
* with an Adafruit Feather nRF52840 Express
|
||||||
|
*
|
||||||
|
* HamShield to Feather Connections:
|
||||||
|
* SPKR - Feather A0
|
||||||
|
* MIC - Feather D11
|
||||||
|
* CLK - Feather D5
|
||||||
|
* nCS - Feather D6
|
||||||
|
* DAT - Feather D9
|
||||||
|
* GND - Feather GND
|
||||||
|
* VCC - Feather 3.3V
|
||||||
|
*
|
||||||
|
* Connect the HamShield to your Feather as above.
|
||||||
|
* Screw the antenna into the HamShield RF jack. Plug a pair
|
||||||
|
* of headphones into the HamShield.
|
||||||
|
*
|
||||||
|
* Connect the Feather nRF52840 Express to your computer via
|
||||||
|
* a USB Micro B cable. After uploading this program to
|
||||||
|
* your Feather, open the Serial Monitor. You should see some
|
||||||
|
* text displayed that documents the setup process.
|
||||||
|
*
|
||||||
|
* Once the Feather is set up and talking to the HamShield,
|
||||||
|
* you can control it over USB-Serial or BLE-Serial(UART).
|
||||||
|
*
|
||||||
|
* Try using Adafruit's Bluefruit app to connect to the Feather.
|
||||||
|
* Once you're connected, you can control the HamShield using
|
||||||
|
* the same commands you'd use over USB-Serial. The response to
|
||||||
|
* all commands will be echoed to both USB-Serial and BLE-Serial(UART).
|
||||||

Mode ASCII Description
|
||||||
|
-------------- ----------- --------------------------------------------------------------------------------------------------------------------------------------------
|
||||||
|
Transmit space Space must be received at least every 500 mS
|
||||||
|
Receive not space If space is not received and/or 500 mS timeout of space occurs, unit will go into receive mode
|
||||||
|
Frequency F<freq>; Set the receive frequency in KHz, if offset is disabled, this is the transmit frequency
|
||||||
|
Morse Out M<text>; A small buffer for morse code (32 chars)
|
||||||
|
Morse In N; Sets mode to Morse In, listening for Morse
|
||||||
|
Power level P<level>; Set the power amp level, 0 = lowest, 15 = highest
|
||||||
|
Enable Offset R<state>; 1 turns on repeater offset mode, 0 turns off repeater offset mode
|
||||||
|
Squelch S<level>; Set the squelch level
|
||||||
|
TX Offset T<freq>; The absolute frequency of the repeater offset to transmit on in KHz
|
||||||
|
RSSI ? Respond with the current receive level in - dBm (no sign provided on numerical response)
|
||||||
|
Voice Level ^ Respond with the current voice level (VSSI), only valid when transmitting
|
||||||
|
DTMF Out D<vals>; A small buffer for DTMF out (only 0-9,A,B,C,D,*,# accepted)
|
||||||
|
DTMF In B; Sets mode to DTMF In, listening for DTMF
|
||||||
|
PL Tone Tx A<val>; Sets PL tone for TX, value is tone frequency in Hz (float), set to 0 to disable
|
||||||
|
PL Tone Rx C<val>; Sets PL tone for RX, value is tone frequency in Hz (float), set to 0 to disable
|
||||||
|
Volume 1 V1<val>; Set volume 1 (value between 0 and 15)
|
||||||
|
Volume 2 V2<val>; Set volume 2 (value between 0 and 15)
|
||||||
|
KISS TNC K; Move to KISS TNC mode (send ^; to move back to normal mode). NOT IMPELEMENTED YET
|
||||||
|
Normal Mode _ Move to Normal mode from any other mode (except TX)
|
||||||
