/*
https://github.com/gabest11/esphome-cc1101
This is a CC1101 transceiver component that works with esphome's remote_transmitter/remote_receiver.
It can be compiled with Arduino and esp-idf framework and should support any esphome compatible board through the SPI Bus.
On ESP8266, you can use the same pin for GDO and GD2 (it is an optional parameter).
The source code is a mashup of the following github projects with some special esphome sauce:
https://github.com/dbuezas/esphome-cc1101 (the original esphome component)
https://github.com/nistvan86/esphome-q7rf (how to use esphome with spi)
https://github.com/LSatan/SmartRC-CC1101-Driver-Lib (cc1101 setup code)
TODO: RP2040? (USE_RP2040)
