Based on CC1101 library by Christian Weithe
Included example demo application
Configure your esp32 build environment as for other esp-idf examples
Clone the repository
git clone https://github.com/loboris/ESP32_CC1101_Library.git
Execute menuconfig and configure your Serial flash config and other settings. Included sdkconfig.defaults sets some defaults to be used.
Navigate to CC1101 Example configuration and set CC1101 and example parameters:
make menuconfig
Make and flash the example.
make all && make flash
