I have a source file that is about 80k. By the time it becomes an application, the bundle is many megabytes.
What is the forum limit for zip archives?

VonSzarvas

The forum limit for uploads (attachments) is 2 megabytes
And to keep stats together, the limit for post content is 15000 characters.

Heater.

....and it's time to put it up on github or bitbucket and link to it from a forum post.

What on Earth have you got in there ?

potatohead

Yep. Agreed.

I did hit the 15K once. Sheesh.

Lotsolibraries that I didn't write and don't understand:)

GitHub is scary...

Dropbox isn't scary. Just make a zip and "drop" it off. Make it public, post a link and there you go!

I totally fail to see how you end up with "many megabytes" when you are zipping up a Propeller project.

Get a grip. What is the other Smile you have in there.

Github is your friend

If the library code is available elsewhere you could just link to it. Also, everything posted to the forum should be under MIT license. If the library source code isn't MIT license you shouldn't post it here. Is the megabytes of stuff compiled libraries? I'm curious how this fits in a processor with 32K of RAM, or are they files that go on an SD card?

I think the problem is that when SimpleIDE makes a zip file it includes every library that you've used in source form.

David,

I think the problem is that when SimpleIDE makes a zip file it includes every library that you've used in source form.

So that is a few 10s of kilobytes. What is the other junk?

The entire GCC toolchain? :-)

Eeek!

I am implementing a utility program called Propeller2Explorer. I started it as a way to get data in and out of the P2V. I am using Processing 3 from Processing.org. It allows you to hook up a camera and a Kinect V2 and control them with the P2v.

Programs are called sketches. In order to write and use a sketch you have to download and install Processing 3. It is all free and cross platform, but it takes time and fiddling. Once you do that you have to go get the latest versions of several libraries that are not included. More fiddling and fussing around. On the other hand, Processing 3 allows you to generate a full applications. But in order to use the application you have to have the right Java installed... or... that can be embedded directly in the application... and whallllah you get 8Megs. For Linux the application is about 1M because Java can't be embedded. I am using a GUI library, with no Mac support, so it isn't fully cross platform.

The attached jpg is a picture of the Propeller2v taking a picture of itself, while the Kinect V2 measures the Propeller's video monitor...

What I find most amazing is that this is running on a $99 Kangaroo that JMG pointed me to in one of the threads here...about the size of a pack of cigarettes... just fabulous.

Was that tell post or test poll? And was there a conveyor belt involved?

Absolutely hysterical. I tried posting to that thread... the forum didn't crash, but nothing else seemed to happen.

Looking at Dropbox now. Fingers crossed.

Java...Eeew.

rjo__

It isn't Java... Java has a learning curve. Processing 3, the learning curve is about 10 minutes. I wouldn't care if they based it on Ada:) It's a tinker toy:) Lotsofun

Heater.

Yes, but it sits on a pile of Java Virtual Machine. Eeew.

Still, if it's fun, why not.

So true:)

And while I am tinkering with it to support the P2v, it could easily be adapted to work with the Prop1, BasicStamp or ... you know, those other controllers.

Currently implemented of general interest:
On a Kangaroo:
Serial... supports up to 460800 baud rate.
Camera ... one USB camera 30 FPS
Kinect V2 around 6 FPS with all the bells and whistles. With just RGBdepth map ... it is reporting 60 FPS. This is probably wrong but it looks pretty good.

There are two choices of libraries supporting the Kinect V2 for Processing 3. They are mutually exclusive because they use different USB3 drivers.

I am using Daniel Shiffman's OpenKinect library, which isn't entirely complete yet, but does have the color mapping functions, which I couldn't get to work in the other library. Daniel's library supports use on the Mac. I haven't done this yet, but the calls should work. My app doesn't work on a mac because the GUI library I am using "controlP5" isn't available for the Mac.

Decoding the depth map to actual 3d measurements isn't readily available in either of these libraries in a way that I could get at, so the 3D measurements you see rely on my own math which isn't complete, but is very simple and gives a reasonable first pass at it. I have a lot on my "to do" list. I wrote my own routine for flipping the raw depth data so that the image isn't mirrored on the screen and so that the depth measurements correspond to the cameras view. Then I found out that there is a call for this, which is much faster... this would probably double the available frame rate.

On the P2 side of things, this can best be viewed as a stub. What is currently implemented with several examples is how to use the P2 to control the app and how to use the app to control the P2... again, this can all be generalized for any controller.

If you want to try this... you have to download the libraries through the Processing 3 and follow

Daniel Shiffman's

instructions for changing out the USB3 driver. And you should be good to go. If you have a P123, the keyboard interface on the computer side is:

h... hub buffer to lut
o... do op and move to lut 0
l... lut to hub
i... send image to serial
c... copy cog to (lut thanks Ariba!!!)
r... read lut from serial
a... send 512 bytes array to serial
p... write keyboard to P2 screen.... not implemented yet

As you can see... on the P2 side... the interface loop is P1 code compatible.
