Dear all,

I am using Chipkit UNO32 . I am looking for IDE similar to Arduino. I have MPide IDE i found issue Library function. I have this IDE from LAST 2 year,

Question:

1. Is there any new version Of iDE being introduced With Update Library functions 2)I have project running on UN032. Project about solar tracker. This tracker being installed in 2000 meter from Home. I wanted to monitor parameter from solar tracker. Initially i used Serial Monitor to view data. Since for long distance which protocol Will be useful. Also Easy to implement using above IDE

Latest versions of the IDE are available here: [url]http://chipkit.s3.amazonaws.com/index.html[/url]

There is also UECIDE, which is a better interface that MPIDE: [url]http://uecide.org[/url]

For long distance wired communication you want RS-485 with a repeater after 1km.

You may be able to get away with a single run without the repeater if you run at a low baud rate:

A rule of thumb is that the speed in bit/s multiplied by the length in meters should not exceed 10^8

9600*2000 = 19200000 == 1.92 x 10^7

which is just acceptable. No guarantees though as the quoted maximum length on Wikipedia is 1200m.

In attached link which version of IDE is More useful. That support all library like Arduino.[attachment=0]mpide v.JPG[/attachment]. And also Suggest me the Sheild that can compatible with CHipkit UNO32 MODULE. to achieve above project

There is no version of MPIDE that will run all Arduino libraries, and there never will be. Please read this:

Another comms option might be to use GSM (mobile phone network) to communicate. That's not restricted by distance, only mobile phone signal availability. Of course, it costs though.

If you want to go the wired route, though, you should first read up on RS-485 networks and how they work. The choice of a "shield" (I loathe that word) would then become a fairly moot point as you would have a clue as to what you are looking for then.

I am trying to implement master slave Configuration with chipkit UNO32/ I have SCADA system which acts as Master. And i have 2 chipkit uno board acts slave. Is there any modbus slave library available for chipkit UNO32 . SO make some trial run , later i can modify to my code.If you are aware of such thing requested to share link.
