This page presents the getting started guide of the Esus board.

Presentation

Power	2.8 – 11.8 V
Microcontroller	ESP8266 80 Mhz
Analog Input Pins	6
Mini-usb connector	programming Esus board
On/Off switch	Turn on and off the board. The PWR green led will light when power on.
10 pins connector	+3.3V : 3.3 Volt tension GND : ground pins SCK/IO14 : SPI clock or GPIO n°14 MISO/IO12 : Master Input Slave Output of SPI bus or GPIO n°12 MOSI/IO13 : Master Output Slave Input of SPI bus or GPIO n°13 IO2 : GPIO n°2 TX/IO1 : serial UART (transmit) or GPIO n°1 RX/IO3 : serial UART (receive )or GPIO n°3 GND : ground pins +5V : +5V tension
H bridge out	Two outputs on screw terminals for the control of two DC motors. Output current 1A per channel max.
Analog inputs (A0 – A5)	8 bits resolution, Input tension : 0-3.3V  0 V = 0 3.3V = 1023
Logic inputs (I2 – I3)	Logic inputs (0 or3.3V)

Arduino IDE installation

• Dowload Arduino IDE : https://www.arduino.cc/en/Main/Software

Configuration

The first step is the configuration of the Arduino IDE for support the ESP8266 microcontroller.

• Open Arduino IDE.
• Next:
  • File->Preferences

• Additional Boards Manager URLs :

http://arduino.esp8266.com/stable/package_esp8266com_index.json

• Click Ok
• Then , menu : Tools->Boards Managers :
  

• Then, search « esp8266 » :

• Install « esp8266 by ESP8266 Community » :

• Tools->Boards :
  

Blink exemple :

• Verify and uploid the program :

Install Esus libraries

• Dowload arduino lib for Esus lib : here
  • Software/Arduino

Then, puts this files in the repertory “libraries” of Arduino IDE :

• esusBoard.cpp
• esusBoard.h

• Repertory EsusBoard with .c and .h files:

• Now, you can program the Esus board.

A simple exemple

#include <esusBoard.h>

int ledPin = 2;

void setup() 
{
  // initialisation
  initEsusBoard();

  // initialisation output
  pinMode(ledPin, OUTPUT);

}

void loop() 
{
  // turn on the led
  digitalWrite(ledPin, HIGH);

  // 2 secondes (2000 ms)
  delay(2000);

  // turn off
  digitalWrite(ledPin, LOW);

  delay(2000);
}
