GND GND
GPIO 18 SCK
GPIO 19 MOSI
GPIO 16 MISO
GPIO 7 DIO0 / G0
GPIO 8 NSS / CS
GPIO 9 RESET
GPIO 10 DIO1 / G1

Default Pinout can be overrided with setPins() function

Installation

  1. Set up the Pico C/C++ SDK
  2. Download this repo
  3. Set PICO_SDK_PATH
export PICO_SDK_PATH="path to pico-sdk"
  1. Create build directory then run cmake and make:
mkdir build
cd build
cmake ..
make

Notes
