OneWire Lib

Woow...I supposed it was same sort of error message.

Going deep further the following code for DS1820 works like a charm ;)
Thank you Gordon!

readTemp = function(){
var ow = new OneWire(C10); 
ow.device = ow.search()[0];
ow.reset();
ow.select(ow.device); 
ow.write(0x44, true);
ow.reset();
ow.select(ow.device);
ow.write(0xBE);
var a = 3-1;
var temp_l = ow.read();
var temp_h = ow.read();
var th = ow.read();
var tl = ow.read();
var res1 = ow.read();
var res2 = ow.read();
var count_remain = ow.read();
var count_per_c = ow.read();
var temp_read = ((temp_l + (temp_h<<8))-1)/2;
var t = temp_read - 0.25 + (count_per_c - count_remain)/count_per_c;
return t;
};
