Programming

Running with FoBE Quill ESP32S3 Mesh

Let's get started with the FoBE Quill ESP32S3 Mesh using the MFP interface.

Connect the FoBE Breakout ENS160 to the FoBE Quill ESP32S3 Mesh using the MFP interface.

Create a sketch or PlatformIO project, or follow the FoBE Quill ESP32S3 Programming Guide for pre-configuration.
Install the necessary library in your project:

sciosense/ScioSense_ENS16x@^2.0.4

Copy the following code into your sketch or PlatformIO project:

#include <ScioSense_ENS16x.h>

#define I2C_ADDRESS 0x52        // I2C address definition (H: 0x53, L: 0x52), check your jumper settings
#define I2C_SDA_PIN PIN_MFP3    // SDA pin for MFP to I2C cable, change if needed
#define I2C_SCL_PIN PIN_MFP4    // SCL pin for MFP to I2C cable, change if needed
#define PERI_EN_PIN PIN_PERI_EN // Peripheral enable pin, change if needed

ENS160 sensor;

void setup()
{
  // Initialize serial communication
  Serial.begin(115200);
  Serial.println("Serial initialized");

  // Initialize peripheral power
  if (PERI_EN_PIN >= 0)
  {
    pinMode(PERI_EN_PIN, OUTPUT);
    digitalWrite(PERI_EN_PIN, HIGH); // Enable peripheral power
    Serial.println("Peripheral power enabled");
  }

  // Initialize sensor
  Wire.begin(I2C_SDA_PIN, I2C_SCL_PIN);
  sensor.begin(&Wire, I2C_ADDRESS);
  Serial.println("I2C bus initialized");
  while (sensor.init() != true)
  {
    delay(200);
  }
  Serial.println("ENS160 sensor initialized");

  // Start measurement
  sensor.startStandardMeasure();
}

void loop()
{
  sensor.wait();

  if (sensor.update() == RESULT_OK)
  {
    if (sensor.hasNewData())
    {
      // Display data on screen
      Serial.print("\033[H\033[J");
      Serial.println("> FoBE Breakout ENS160 Monitor");
      Serial.println();
      Serial.print("\033[7m");
      Serial.printf("%-12s%-12s%-12s\n", "INDEX", "VALUE", "UNIT");
      Serial.print("\033[0m");
      Serial.printf("%-12s%-12d%-12s\n", "AQI", sensor.getAirQualityIndex_UBA(), "UBA");
      Serial.printf("%-12s%-12d%-12s\n", "TVOC", sensor.getTvoc(), "ppb");
      Serial.printf("%-12s%-12d%-12s\n", "ECO2", sensor.getEco2(), "ppm");
      if (sensor.hasNewGeneralPurposeData())
      {
        Serial.printf("%-12s%-12d%-12s\n", "RS0", sensor.getRs0(), "Ohm");
        Serial.printf("%-12s%-12d%-12s\n", "RS1", sensor.getRs1(), "Ohm");
        Serial.printf("%-12s%-12d%-12s\n", "RS2", sensor.getRs2(), "Ohm");
        Serial.printf("%-12s%-12d%-12s\n", "RS3", sensor.getRs3(), "Ohm");
      }
    }
  }
}

important

This example code uses ANSI output formatting. Your terminal must support ANSI escape codes to display the output correctly.

# platformio.ini
[env:fobe_quill_esp32s3_mesh]
platform = FoBE Espressif 32
board = fobe_quill_esp32s3_mesh
framework = arduino
lib_deps = 
	sciosense/ScioSense_ENS16x@^2.0.4
monitor_speed = 115200
monitor_raw = true

Build and upload the project. You should see the FoBE Breakout ENS160 Monitor output in the serial monitor (raw mode).
