I'm working on a project involving a Controllino MEGA and I've read that there are more than 2 interrupts available:
The Arduino Uno has 2 and the Mega has 6 external interrupt pins available:
Arduino Uno/Controllino MINI/INT.x interrupt: 2/IN0/INT.0 – 3/IN1/INT.1
Arduino Mega/Controllino MAXI,MEGA/INT.x interrupt: 2/D0/INT.0 – 3/D1/INT.1 – 18/IN0/INT.5 – 19/IN1/INT.4 – 20/SDA/INT.3 – 21/SCL/INT.2
I've tried to wire my 24V sensors directly on the pins D20, or D21 but they are in the OUTPUT side of the board (and when I activate the sensors there is no led on the board indicating that the sensor triggering has been detected).
Is there any way that allows me to use a third interrupt with a 24V sensor with a Controllino MEGA board?
Thanks in advance for any help.
