A tutoriel to read analog input with Esus board.

How to read an analog input ?

To read an analog input, here is a function to be used:

unsigned int MCP3008_read(int channel);

This function returns a value between 0 and 1023. In parameter, the channel is a value between A0 and A5.

Read analog input A0

Here is an example of reading  the A0 analog input.

#include <esusBoard.h>
unsigned int data;

void setup() 
{
  // init esus board
  initEsusBoard();

  Serial.begin(9600);
  
}

void loop() 
{
  data = MCP3008_read(A0);

  Serial.println(data);

  delay(1000);
}

Read all inputs

Program for read all the analog input:

#include <esusBoard.h>
unsigned int data,c;

void setup() 
{
  // init esus board
  initEsusBoard();

  Serial.begin(9600);
  
}

void loop() 
{
  for(c=0;c != 6; c++)
  {
    data = MCP3008_read(c);
    Serial.println(data); 
    delay(1000);
  }

}
