ANALOG INPUTS

Voltage variation  between  –Vcc (or GND)  and  +Vcc, can take any value. An analog input provides a coded measurement in the form of a
digital value with an N-bit number.  In Digital and Analog I/O there’s self insulation, so its posible to connect them in a different power supply
than 24 V.  

Inputs: (6x) of 10x, Analog (0-10Vdc) configurable by Software.

TYPICAL CONNECTION

DIGITAL INPUTS

Voltage variation  from  –Vcc (or GND)  to  +Vcc, with no intermediate values. Two states: 0 (-Vcc or GND) and 1 (+Vcc).  In Digital and Analog I/O there’s self insulation, so its posible to connect them in a different power supply than 24 V.  

Inputs: (10x) Digital (5-24Vdc).

TYPICAL CONNECTION

- Digital Isolated Input

 

- Digital No Isolated Input 

INTERRUPT INPUTS

Interrupt Service Rutine.  A mechanism that allows a function to be associated with the occurance of a particular event. When the event
occurs the processor exits immediately from the normal flow of the program and runs the associated ISR function ignoring any other task. 

Inputs:  (1x) Interrupt Inputs (5-24Vdc). “Can work like Digital Input (24Vdc)”. 

TYPICAL CONNECTION

In this example we activate INT0 using pin I0_0 from M-duino board. When there’s a change  

#define INTERRUPT I0_0 //other pins: I0_1, I0_6, I2_6, I2_5, I1_6, I1_5 (M-Duino) I0_0, I0_3, I0_2, I0_1 (Ardbox)

volatile bool state = false;

void setup() {
  pinMode(INTERRUPT, INPUT_PULLUP);
  attachInterrupt(digitalPinToInterrupt(INTERRUPT), function_call_back, CHANGE);
}

void loop() {
  if (state == true){
    Serial.println("Interrupt activated");
    state = false;
  }
}
void function_call_back(){ //Change led state
  state = true;
}
