Raspberry Pi 3 GPIO pins equivalence #53

Open BehindTheSciences opened 6 years ago

BehindTheSciences commented 6 years ago

I just wanted to check if my GPIO pin 23 is the Wiring Pin 4. In other words, my RX data pin is connected to Wiring Pin 4 as it's shown in that picture. but is that correct also for Raspberry Pi 3? Because I don't receive any data. I edited the RFSniffer.cpp file, where it says "int PIN = 2;" I put "int PIN = 4;" is that correct? If so, something else may be wrong.
