Arduino sketch for ESP8266 and MOD-BMP085
« on: May 28, 2015, 02:03:52 PM »
For ESP8266-EVB - SDA and SCL match GPIO2 / SDA, GPIO4 / SCL (6 and 5 UEXT I2C on ESP8266-EVB). For used in this case, the library can write Wire.begin (2,4)?

Code: [Select]
// Configure the framework
#include "bconf/MCU_ESP8266.h"              // Load the code directly
on the ESP8266
#include "conf/Gateway.h"                   // The main node is the
Gateway, we have just one node
#include "conf/DynamicAddressing.h"         // Use dynamic addressing


// Define the WiFi name and password
#define WIFICONF_INSKETCH
#define WiFi_SSID               "SSID"
#define WiFi_Password           "PASSWORD"


// Include framework code and libraries
#include <ESP8266WiFi.h>
#include <EEPROM.h>
#include "Souliss.h"


// This identify the number of the LED logic
#define PRESSURE0    0
#define BMP180TEMP    2


// SDA and SCL pins can be configured, you need to edit
SFE_BMP180/SFE_BMP180.cpp line 38. Preconfigured at 14, 12.
#include <SFE_BMP180.h>
#include <Wire.h>
#define ALTITUDE 20.0 // Altitude of reading location in meters


// You will need to create an SFE_BMP180 object, here called "pressure":
SFE_BMP180 pressure;




void setup()
{
    Initialize();
    Serial1.begin(115200);
    // Connect to the WiFi network and get an address from DHCP

    GetIPAddress();
    SetAsGateway(myvNet_dhcp);       // Set this node as gateway for
SoulissApp


    if (pressure.begin())
       Serial1.println("BMP180 init success");
    else
     {
              // Oops, something went wrong, this is usually a
connection problem,
              // see the comments at the top of this sketch for the
proper connections.

              Serial1.println("BMP180 init fail\n\n");

      }


}


void loop()
{

    EXECUTEFAST() {
        UPDATEFAST();

        // Here we handle here the communication with Android
        FAST_GatewayComms();
    }

 UPDATESLOW();


            SLOW_10s() {  // Read temperature and humidity from DHT
every 110 seconds


              Souliss_GetPressure_BMP180(PRESSURE0,BMP180TEMP);
