Programming #
The NORVI AGENT 1-BT05-ES-N 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-BT05-ES-N can be configured as both sink and source connections. The inverse of the Digital Input polarity should be supplied to the common terminal.
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 state, 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);
}
0 – 10V 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(21,22);
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);
}
Relay Output #
Wiring Relay Outputs #
Programming Relay Outputs #
Reading the relevant GPIO of the ESP32 gives the value of the relay output. Refer to the GPIO allocation table in the datasheet for the relay output GPIO.
#define OUTPUT1 13
void setup() {
Serial.begin(115200);
Serial.println("Device Starting");
pinMode(OUTPUT1 , OUTPUT);
}
void loop() {
digitalWrite(OUTPUT1, HIGH);
