RadioLib Si443x Settings Example
|
|
|
|
This example shows how to change all the properties of RF69 radio.
|
|
RadioLib currently supports the following settings:
|
|
- pins (SPI slave select, nIRQ, shutdown)
|
|
- carrier frequency
|
|
- bit rate
|
|
- receiver bandwidth
|
|
- frequency deviation
|
|
- output power during transmission
|
|
- sync word
|
|
|
|
For default module settings, see the wiki page
|
|
https://github.com/jgromes/RadioLib/wiki/Default-configuration#si443xrfm2x
|
|
|
|
For full API reference, see the GitHub Pages
