This guide shows how to make the first Arduino IDE upload and check digital I/O on every MPINO and MPAINO model. Read the model name on the product label and make sure it matches the board name below.

The board name and I/O numbers depend on the product. Find your model below and use the settings shown for it. R identifies a relay-output model; T identifies a SINK transistor-output model.

1. Install the Windows Arduino IDE from the official Arduino download page.
2. Download and run ARDUINO SDK INSTALL from the ILOGICS Arduino SDK download page.
3. Close Arduino IDE and start it again.

At the top left of Arduino IDE, Verify (✓) compiles the code and Upload (→) transfers it to the product on the selected port.

The ILOGICS SDK configures digital I/O directions automatically. These examples do not need a separate pinMode() call.

Disconnect output loads before the first upload. Check the product page for the power specification and R (relay) or T (transistor) output type.

1. Connect the PC to the CPU module's USB download port with a USB cable.
2. In Windows Device Manager → Ports (COM & LPT), note the COM number shown for Silicon Labs CP210x USB to UART Bridge(COMx).
3. If the port does not appear, install the CP210x USB driver and reconnect the cable.

1. Connect the PC to the product's USB download port with a USB cable.
2. In Device Manager, note the COM number shown for Silicon Labs CP210x USB to UART Bridge(COMx).
3. If the port does not appear, install the CP210x USB driver and reconnect the cable.

1. Connect the PC to the product's download port with an ILOGICS MP Download Cable. Do not substitute an ordinary USB cable or another USB-to-TTL adapter.
2. In Device Manager, note the COM number shown for USB Serial Port(COMx).
3. If the port does not appear, install the FTDI driver for the MP Download Cable and reconnect it.

Open Select other board and port… from the board selector at the top of Arduino IDE. The product name in the figure is only an example of the selection method. Search for the exact board name shown in section 1.

In PORTS, select the COM number found in Device Manager.

You can also select the same items from Tools → Board and then Tools → Port.

Find your model's I/O group in section 1 and use the matching example. Open File → New Sketch, enter the code, and save it with Ctrl + S. Select Verify (✓) and wait for Done compiling., then select Upload (→).

A relay output can be checked by its operating sound. To check a transistor output, switch off power and connect a test load according to the output-wiring section on the product page.

const uint8_t OUTPUT_CHANNEL = 64;  // first MPAINO output
 
void setup() {}
 
void loop() {
  digitalWrite(OUTPUT_CHANNEL, HIGH);
  delay(500);
  digitalWrite(OUTPUT_CHANNEL, LOW);
  delay(500);
}

Use this example with MPINO-8A4R(T)-S, MPINO-8A4R-SU, MPINO-8A8R(T)-S, and MPINO-16A16R.

const uint8_t OUTPUT_CHANNEL = 32;  // first output on these MPINO models
 
void setup() {}
 
void loop() {
  digitalWrite(OUTPUT_CHANNEL, HIGH);
  delay(500);
  digitalWrite(OUTPUT_CHANNEL, LOW);
  delay(500);
}

To test transistor output O(39) on MPINO-16A8R8T, check the transistor-output wiring on its product page and change OUTPUT_CHANNEL to 39.

const uint8_t OUTPUT_CHANNEL = 62;  // relay output R(62)
 
void setup() {}
 
void loop() {
  digitalWrite(OUTPUT_CHANNEL, HIGH);
  delay(500);
  digitalWrite(OUTPUT_CHANNEL, LOW);
  delay(500);
}

const uint8_t OUTPUT_CHANNEL = 39;  // relay output R(39)
 
void setup() {}
 
void loop() {
  digitalWrite(OUTPUT_CHANNEL, HIGH);
  delay(500);
  digitalWrite(OUTPUT_CHANNEL, LOW);
  delay(500);
}

Switch off power before wiring the input and COM. Turn the input on and off and check that the output follows it. Use the Digital Inputs and Output sections of your product page to identify the terminals and COM.

const uint8_t INPUT_CHANNEL = 0;   // first MPAINO input
const uint8_t OUTPUT_CHANNEL = 64;
 
void setup() {}
 
void loop() {
  const bool inputOn = digitalRead(INPUT_CHANNEL);
  digitalWrite(OUTPUT_CHANNEL, inputOn);
}

const uint8_t INPUT_CHANNEL = 0;   // first input on these MPINO models
const uint8_t OUTPUT_CHANNEL = 32;
 
void setup() {}
 
void loop() {
  const bool inputOn = digitalRead(INPUT_CHANNEL);
  digitalWrite(OUTPUT_CHANNEL, inputOn);
}

const uint8_t INPUT_CHANNEL = 22;   // input I(22)
const uint8_t OUTPUT_CHANNEL = 62;
 
void setup() {}
 
void loop() {
  const bool inputOn = digitalRead(INPUT_CHANNEL);
  digitalWrite(OUTPUT_CHANNEL, inputOn);
}

const uint8_t INPUT_CHANNEL = 22;   // input I(22)
const uint8_t OUTPUT_CHANNEL = 39;
 
void setup() {}
 
void loop() {
  const bool inputOn = digitalRead(INPUT_CHANNEL);
  digitalWrite(OUTPUT_CHANNEL, inputOn);
}
