RadioLib SX127x Morse Receive AM Example
|
||||
|
||||
This example receives Morse code message using
|
||||
SX1278's FSK modem. The signal is expected to be
|
||||
modulated as OOK, to be demodulated in AM mode.
|
||||
|
||||
Other modules that can be used for Morse Code
|
||||
with AFSK modulation:
|
||||
- SX127x/RFM9x
|
||||
- RF69
|
||||
- SX1231
|
||||
- CC1101
|
||||
- Si443x/RFM2x
|
||||
|
||||
For default module settings, see the wiki page
|
||||
https://github.com/jgromes/RadioLib/wiki/Default-configuration
|
||||
|
||||
For full API reference, see the GitHub Pages
