  Hi - trying to solve an issue using an espruino pico and an sd card loggin gps and other sensor data

  when connected to the usb and the ide it functions fine and logs the data as csv but as soon as i go to standalone mode using a battery nothing seems to happen

  i have placed it all in onInit but can't seem to get anything going

  any help would be super appreciated as i am super up against a project deadline on this thanks

  function oninit(){
  // Wire up up MOSI, MISO, SCK and CS pins (along with 3.3v and GND)
  SPI1.setup({mosi:B5, miso:B4, sck:B3});
  E.connectSDCard(SPI1, B1 /*CS*/);
  // see what's on the device
  //console.log(require("fs").readdirSync(­));
    Serial1.setup(9600,{tx:B6,rx:B7});
   require("fs").appendFileSync("data2.csv"­ , "new");
  var gps = require("GPS").connect(Serial1, function(data) {
  SPI1.setup({mosi:B5, miso:B4, sck:B3});  
  E.connectSDCard(SPI1, B1 /*CS*/);
    
  //var fs = E.openFile("data2.csv","w");
    i++;
   var readings = [
      analogRead(A0),
      analogRead(A1),
      analogRead(A2),
     data.lat,
     data.lon,
     data.time
    ];
   //f.write(readings.join(", ")+"\n");  
    ar=analogRead(A2);
    //console.log(readings);
    require("fs").appendFileSync("data2.csv"­ , readings.join(", ")+"\n");
   // f.close();
  });
  
  setInterval(gps, 1000);
  
    
  }
  function gps(){
  
  var fs;
  var i=0;
  var gps = require("GPS").connect(Serial1, function(data) {
  SPI1.setup({mosi:B5, miso:B4, sck:B3});  
  E.connectSDCard(SPI1, B1 /*CS*/);
    
  //var fs = E.openFile("data2.csv","w");
    i++;
   var readings = [
      analogRead(A0),
      analogRead(A1),
      analogRead(A2),
     data.lat,
     data.lon,
     data.time
    ];
   //f.write(readings.join(", ")+"\n");  
    ar=analogRead(A2);
    //console.log(readings);
    require("fs").appendFileSync("data2.csv"­ , readings.join(", ")+"\n");
   // f.close();
  });
  
  }
  oninit(); 
  save();
