USER GUIDE - NORVI Industrial Arduino

Programming #

The NORVI AGENT 1-BT02-LTE has a mini USB port for serial connection with the SoC for programming. Any ESP32 supported programming IDE can be used to program the controller. Follow this Guide to programming NORVI ESP32-based controllers with the Arduino IDE.

SoC: ESP32-WROVER-B
Programming Port: USB UART

Digital Inputs #

Wiring Digital Inputs #

The digital inputs of NORVI AGENT 1-BT02-LTE can be configured as both sink and source connections. The inverse of the Digital Input polarity should be supplied to the common terminal.

NORVI AGENT 1-BT02-LTE Digital Input Wiring

Programming Digital Inputs #

Reading the relevant GPIO of the ESP32 gives the value of the Digital Input. When the inputs are in the OFF state, the GPIO goes HIGH, and when the input is in the ON stage, the GPIO goes LOW. Refer to the GPIO allocation table in the datasheet for the digital input GPIO.

#define INPUT1 18 
void setup() { 
   Serial.begin(115200); 
   Serial.println("Device Starting"); 

   pinMode(INPUT1, INPUT); 
} 
void loop() { 
   Serial.print(digitalRead(INPUT1));
   Serial.println(""); 
   delay(500); 
}

Analog Input #

Wiring Analog Inputs #

Reading Analog Input #

Reading the relevant I2C address of the ADC gives the value of the Analog Input.

Programming Analog Inputs #

#include <Adafruit_ADS1X15.h> 

#include <Wire.h> 

Adafruit_ADS1115 ads1; 

void setup() { 
   Serial.begin(115200); 
   Serial.println("Device Starting"); 

   Wire.begin(16,17); 
   ads1.begin(0x48); 
   ads1.setGain(GAIN_ONE); 
} 

void loop() { 
Serial.print("Analog 0 ");Serial.println(ads1.readADC_SingleEnded(0));  delay(10); 
Serial.print("Analog 1 ");Serial.println(ads1.readADC_SingleEnded(1)); delay(10); 
Serial.print("Analog 2 ");Serial.println(ads1.readADC_SingleEnded(2)); delay(10); 

Serial.println(""); 
delay(500); 
}

Transistor Output #

Wiring Transistor Outputs #

Programming Transistor Outputs #

Reading the relevant GPIO of the ESP32 gives the value of the Transistor Output. Refer to the GPIO allocation table in the datasheet for the Transistor Output GPIO.

#define OUTPUT1 23
void setup() { 
   Serial.begin(115200); 
   Serial.println("Device Starting"); 

   pinMode(OUTPUT1 , OUTPUT); 
} 
void loop() { 
   digitalWrite(OUTPUT1, HIGH); 
   delay(500); 
   digitalWrite(OUTPUT1, LOW); 
   delay(500); 

   Serial.println(""); 
   delay(500); 
}
