Issue “Select Board” despite board being selected.

Is there an issue with this post? Why is it blank?

Hi,

I’m following the tutorial for the Controllino Micro, but I’m running into an issue on macOS when selecting Tools → Board in the Arduino IDE.

I’ve installed the required libraries, and the IDE shows Controllino Micro as the selected board. However, when compiling I get the following error:

#error Please, select one of the CONTROLLINO variants in Tools->Board

Is this a known issue on macOS?

As a workaround, I tried manually defining <code inline=””>CONTROLLINO_MICRO in the code with:

#define CONTROLLINO_MICRO

but that doesn’t resolve the problem either.

Here’s the full script I’m using:

// #define CONTROLLINO_MICRO

#include <SPI.h>
#include <Controllino.h>

void setup() {
    pinMode(CONTROLLINO_MICRO_AI0, INPUT);
    Serial.begin(115200);
}

void read_analog_sensor() {
    int rawValue = analogRead(CONTROLLINO_MICRO_AI0);

    // Convert raw ADC (0–1023) to voltage (0–10 V range at the terminal)
    float voltage = (rawValue / 1023.0) * 3.3;

    Serial.print("Raw ADC value: ");
    Serial.print(rawValue);
    Serial.print(" Voltage at AI0: ");
    Serial.print(voltage, 2); // 2 decimals
    Serial.println(" V");
}

void loop() {
    read_analog_sensor();
}
