I think this is a good place to ask my rookie questions. I also just switched to ARC today. So far so good. My project is all written in EZB scripting. If I understand correctly, my EZ scripts will not run faster in ARC. I have to convert them all to Javascript ? Can EZ scripts coexist with Javascripts ?

Welcome to the new ARC :D

EZ-Script will run slightly faster in ARC than they did in ARC. However, they won't run nearly as fast as JavaScript. You don't have to change over - but for the added reliability and improved performance, it's not a bad idea. Also, JavaScript is a lot of fun!

I'm finding a couple issues. I don't know if it's my new laptop or ARC.

I have a large project that is spread across all three virtual desktops. Screen one looks fine. I have no scroll bars on screen two and three even though my controls extend way down below the bottom of the screen of both desktops. There is no way to scroll down to the controls down under.

I can't find a way to see what version of ARC I have. I do see the version if I load a blank project but if I load my project from a shortcut on my windows desktop there is no way of knowing. I thought it would be visible under the "About" tab but no.

When I do a "Check For New Version" under the Help tab all I see is a quick flash of a window opening and closing and then nothing. I would think there would be a message telling me I had the latest version or tell me I do not and give me instructions on how to get the latest version.

If I have my windows founts set to 125% I get a message at ARC startup that I should run within a recommended resolution and then miss states what resolution I am actually running at. For example I'll have my res set at 1366 X 768 and it ill tell me I'll be running at 1093x614 (96x96 dip). When I change Windows founts back to 100% the error goes away. Your tutorial says fount sizes of 100-125% is recommended. It seems that setting the fount size above 100% messes something up in ARC reporting the actual resolution the computer is running at.

Other then this it's a wonderful experience and works nice.

1. In software programs, the ABOUT window displays the version information - this also includes how to get the version of your windows program. So, click ABOUT in the ARC top menu and you will see the version :)

2. The scrolling has always been a strange issue with windows and the way ARC works. By clicking and moving a control, the scroll bars appear. It's not desired but it's the only way we can seem to get ARC to do that. Also, pressing Smart Arrange seems to fix it as well.

3. The screen resolution that is prompted is because you have the size set to 125%. So your physical resolution + the size scaling. That's what the size scaling does.

@DJ Sures Thanks for your response. It does confirm my understanding. I'm actively converting now, and yes, Javascript is a lot of fun. Somehow, it is kind of familiar as I did some  C# programming years ago.

I do stumble on some obstacles here and there, but with reference to the www.w3schools.com/ as suggested, I'm able to resolve them (except my current array definition issue). Is there Javascript script examples that we can look at ?

Here's a link to using arrays in JavaScript: https://www.w3schools.com/js/js_arrays.asp

David, try this beta release for the scrolling behavior. I'll try a few different things before pushing into next stable release: https://synthiam.com/Products/Releases/ARC-Beta-2020-04-05-00-19321

Thanks DJ for your guidance . I'll give it a try.

OK, Using the Beta-2020-04-05-00-19321 version I now have scroll bars on desktop 2 & 3. Thanks.

I also see the person number in the About section. I guess I'm just blind. LOL.

Thanks once again!

@ DJ Sures Progression from EZB srcipts to ARC scripts progressing very well, and I'm learning too. But back to arrays. I'm still stuck. Creating and accessing array within an ARC script, no problem: Pixel = ["P0","P1","P2","P3","P4","P5","P6","P7","P8","P9","P10","P11","P12","P13","P14","P15"];

_count = 0; while(_count < 16) { print("count = " + _count); print("Pixel = " + Pixel[_count]); _count++; }

But  I need to create the array in Init ARC script, and access the elements in another ARC script (global variable). But when I try to define with the same way as I do for global variables with the setVar(), I get: <<Variable is an array: $Pixel>>   and $Pixel is not shown in the global variable list i(t is not defined) Init script: setVar("$Pixel",["P0","P1","P2","P3","P4","P5","P6","P7","P8","P9","P10","P11","P12","P13","P14","P15"]);

How to define the arrays ?

Oh - I see... You want to push an array from JavaScript to the global variable. You're right, it seems to be not working. I just fixed it now and will publish it in tomorrow's beta channel for ya :)

Oh, btw... you can get the length of an Array in JavaScript with .length... like this...

Pixel = ["P0","P1","P2","P3","P4","P5","P6","P7","P8","P9","P10","P11","P12","P13","P14","P15"];

_count = 0;

while(_count < Pixel.length)
{
print("count = " + _count);
print("Pixel = " + Pixel[_count]);
_count++;
}

or you can simply loop through like this...

Pixel = ["P0","P1","P2","P3","P4","P5","P6","P7","P8","P9","P10","P11","P12","P13","P14","P15"];

for (int i = 0; i < Pixel.length; i++) {

  print("Pixel = " + Pixel[i]);
}

@DJ Sure Thanks. The global variable array definition works (They show up in the global variable listing) setVar("$Pixel",["P0","P1","P2","P3","P4","P5","P6","P7","P8","P9","P10","P11","P12","P13","P14","P15"]); But for some reason, I can not use a variable as an index to retrieve an element. This is ok: print(getVar("$Pixel[15]") ); But this does not work ( I get: << Input string was not in a correct format. >> _count = 0; x = getVar("$Pixel[_count]");

Same thing with a local script: << Input string was not in a correct format. >> _count = 0; x = getVar("Pixel[_count]");

Also, I can not get the .length to work.  setVar("$Pixel",["P0","P1","P2","P3","P4","P5","P6","P7","P8","P9","P10","P11","P12","P13","P14","P15"]); print(getVar("Pixel".length) ); That gives me << Variable not defined: $5 >>

cool

Assign the global variable to a local one.

var myArray = getVar($globalArray);

and then do stuff to that array

It says I have 2020 4.7 beta , a later version

@DJ Sures Yooohooo, it works !!! It took me a while to figure out a syntax error, but I'm not about to gorget it now (hope not). When retrieving elements from the array in the loop, I was coding getVar("$Pixel[_count]"); instead of getVar("$Pixel[" + _count + "]"); Now that I have control over the individual pixels of my Neo-Pixel Ring, I got to figure out how to write to the serial port. In EZB scripting, I was writing: $NeoPixelSerialPin = "0.d18" // Define serial pin (init script) SendSerial($NeoPixelSerialPin,9600,"C0,0,0") // Send string "C0,0,0" to serial port at 9600 baud But now, I assume I must use the COM.  So just open port and send data ? Open port: com.open(port, baud); COM.open(???, 9600); Send data: com.writeString(port, str); COM.writeString(???, "C0,0,0"); Am I close ? What do I write for port ?

Use UART not COM. COM is a com port on the PC. THat's different

@ DJ Sures Working perfectly. Thanks

I may have found an new "feature" with Servo.decrement(port, position) on ARC Version 2020 04.09 Something as simple as <<Servo.decrement(4, 5, 1);>> or <<Servo.decement(4,1)>> moves the servo way more than the value 5 or value 1. It moves all the way to limit setting and it appears that the servo can not be released. ?!?

Servo.decrement fixed in tonight's build on ARC's beta channel
