Key To Your Business

We have been developing custom libraries for Arduino. We have borrowed heavily from Poco while implementing our own libraries (some of which are thin wrappers around native Arduino and Poco classes).


The following sketch is used to test the library.

#include <SPI.h>
#include <Ethernet.h>
#include <WiFi.h>

#include <StandardCplusplus.h>
#include <iostream>

#include <SHttpClient.h>
#include <DateTime.h>
#include <UUID.h>

#include <tut.hpp>

namespace std
{
  ohserialstream cerr(Serial);
  ohserialstream cout(Serial);
}

// A proper unique mac address is critical to having a stable UUID generated
// for events published to Sidecar service.  Please use the MAC address
// printed on the sticker on the sheild
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

// Set the static IP address to use if the DHCP fails to assign
IPAddress ip( 192, 168, 0, 177 );


// Invoke this in setup if you are using ethernet shield for networking
void initEthernet()
{
  if ( Ethernet.begin( mac ) == 0 )
  {
    std::cout << F( "Failed to configure Ethernet using DHCP" ) << std::endl;
    Ethernet.begin( mac, ip );
  }

  // give the Ethernet shield a second to initialize:
  std::cout << F( "Connecting to network..." ) << std::endl;
  delay( 1000 );

  // Initialise network API to use Ethernet
  spt::net::initNetworkType( spt::net::Ethernet );
}


void initUUID()
{
  // Initialise UUID engine
  // If using WiFi, the WiFi api provides a way to look up current MAC
  // address.  That would be better to get proper UUID values.
  spt::UUID::init( mac );
}


// Invoke this in setup if you are using ethernet shield for networking
void initWiFi()
{
  // Perform normal WiFi setup

  // Initialise network API to use WiFi
  spt::net::initNetworkType( spt::net::WiFi );
}
