Dear Friends from RC,

First of all I would like to say thank you for all the information you guys have posted, I have learned so much with this forum. I've been reading it for months and now I can pretty much do all the basic stuff.

Recently I've been trying to deal the prontoscript and actually i got most of things to work when I followed the developer's guide 1.4.3

However I am stuck into something very simple (for all of you)...

My goal is to create a very simple widget that reads the current volume and change its label...

On the page 42 of the guide, I associated the following code to a button:
var e,s;
e = CF.extender[0];
if (!e) {
Diagnostics.log("Extender 0 is not defined");
} else {
s = e.serial[0];
if (!s) {
Diagnostics.log("Extender 0 is not a serial extender");
} else {
s.bitrate = 9600;
s.databits = 8;
s.parity = 0; // None
s.stopbits = 1;
label = s.match("MV?\r","\r",250);
}
}

And it works!

But how do I do for a widget using non asynchronous operation?

where do I put this line:

s.onData = function(v) { label = v; };

How does it work? Which part goes to the "home" and which goes to button or widget advanced panel?

Please please... just give me a step by step guide to create something THIS simple and I promise you I wont bug you guys anymore!

Thank you!!

you put your line anywhere between the last line of setup of the port and before you do your first match operation. as you are doing async 232, you must also handle the onTimeout of the serial port as it is possible that there could be partial message (CR not yet received when the match times out) that you must handle as well. I know you are using serial port but some of the asynchronous example you can find here on sockets should also help to shed some light as to correct placement of the statement. Also note that when you assign an onData function, a call to serial.receive or serial.match no longer returns data and you must examine the single parameter passed during the call to your onData or onTimeout callback functions.

Also go to http://www.the-gordons.net and have a look at some of thr documents that Barry has posted explaining Serial and TCP data communications.

P.S. This thread is best served in the Pronto Pro Forum. Not going to move it unless you would like me to.

Please! :)

Move, im sorry I posted it in the wrong place!

THank you!

Hello Lyndel,

Well I have checked Gordon's page but I have not found any documentation regarding RS-232 except the ones for command fusion.

I so wish I could find a very simple XCF file that would show the denon's receiver volume in "real-time" in a widget.

But I cant find any...

I guess the documentation from Philips is intended for programmers not beginners like me.

If you have time, please help me!


Thank you!

Email me at the addy on my profile and i will send you the prontoscript file from philips site for denon. to fully use this file, you should also have a copy of the protocol spec for your denon receiver. Should be available from denon. You should also consider purchasing the flanagan book referenced in the dev guide. The first 200 pages are applicable for a solid understanding of javascript.
