Detailed Description

Adafruit Feather M0 RFM9x LoRa Radio.

Adafruit Feather M0 RFM9x LoRa Radio를 사용하기 위해서는 이 클래스를 사용하여 인스턴스를 생성해야 합니다.

Examples

feather-m0/AMG88xx_IoT.own/main.cpp, feather-m0/LoRaWAN/main.cpp, feather-m0/TFMini-I2C/main.cpp, and feather-m0/UltimateGPS+OLED/main.cpp.

Constructor & Destructor Documentation

RFM9x()

SystemFeatherM0::RFM9x::RFM9x	(	int8_t	dio1,
		int8_t	dio2,
		int8_t	dio3,
		int8_t	dio4 = -1 )

생성자

LoRa 및 FSK를 사용하기 위해서는 이미 연결되어 있는 DIO0 외에 DIO1~4핀을 별도로 연결해야 합니다. FSK를 사용하지 않는 경우에는 dio4 를 -1 (기본값)로 하십시오.
