I have 1-wire DS2450 A/D numerical data available I would like to convert to binary for simple on/off notification. Can someone please give me some direction as to the proper script to do this for a metadata point?

For example:

If the input is <= 0.5 then output 0 binary
If the input is >0.5 then output 1 binary

I am not familiar with JS programming and syntax (last programming I did was 30 years ago in FORTRAN) and have tried several things with no success.

Thanks in advance!

Hi Mike,

Try this (assuming "x" is the var name you give the point):

Code:

 if (x.value <= 0.5)
     return false;
 return true;

... and set the meta point to be a binary. That ought to do it.

Thanks Matthew.

I actually got it figured out by myself like this:

Code:

if (p33.value<=0.5)
    {
 return false 
    }
 else 
    {
 return true
     }

I see so many different styles of coding for JavaScript on the web, I don't know what is actually required and what is personal preference. Do you know a good resource to learn more?

Anyway if works perfectly. I continue to be amazed at the flexibility and capability of Mango! Now I just need to get my 1-wire network more stable.

Thanks. Re Javascript, just ask Google. There's a ton of resources around.
