Example Code for Arduino-Analog Read

Hardware Preparation

• Romeo for Intel® Edison Controller (Without Intel® Edison)(SKU: DFR0331) ×1
• Intel® Edison Module(SKU: DFR0335) ×1
• micro USB ×1

Software Preparation

• Download Arduino IDE: Click to download Arduino IDE.
• Download DFRobot_Edison library V1.1

Other Preparation Work

1. Download and install the DFRobot_Edison library V1.1 (required for Atmel mega 8 analog pin driver).
2. Open Arduino IDE, select Tools --> Board --> Intel Edison and Tools --> Serial Port --> COM xx.

As Romeo for Edison is using ATmega 8 as Analog pins driver. Please download the DFRobot4Edison library first. The library is keeping update, so some sample code and picture will be different to the old one.

Sample Code

Import two libs, init Serial 9600, read A0 analog value and print periodically.

#include <DFRobot.h>
#include <IIC1.h>

unsigned int value = 0;

void setup() {
 Serial.begin(9600);
}

void loop() {

  value = analogRead(A0);

  Serial.println((int)value);

  delay(2000);
}

Result

The analog value from pin A0 is printed to the serial monitor every 2 seconds.
