I am confusiing about connection between plinto and Arduino UNO.
https://developer.afero.io/docs/en/?target=ModuloUserGd.html (Modulo User Guide)
PIN number of INT is 2 in table “Uno Pins Used When Connected to Modulo via Plinto”.
https://developer.afero.io/docs/en/?target=API-Arduino.html (afLib for Arduino API)
Prameter table of afLib.
mcuInterrupt:The number of the pin to be used to interrupt the Arduino when the radio module needs to communicate. This pin number depends upon the Arduino board you are using. It is 14 for Teensy and 16 for Uno.
It seems that PIN number of INT is 16 for UNO
It is 2. in example progrem of aflib(),
#define INT_PIN 2
I don’t know meanning of 16.
