Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

It looks like numerical limits to me. I had the depth set at 200. 'Pixels' were becoming huge blocks on the screen. (800x600 mode)

Here is another sample, depth even deeper:
(I notice x and y coords are listed twice.)

Interesting!  I wouldn't have thunk it possible.  I guess I've never zoomed in to 1,000,000,000,000,000 X before?  I'll do some more playing with this later.

The coordinates in brackets are for the current view and the second set of X,Y coordinates is for the current cursor position.

Also I just notice that the "C" command key for re-centering on the cursor position never made it to the help screen.  It has been working all along and I will add it to the help screen in the next version.

Here is Mandelbrot Explorer V0.98

The Undo Buffer is working (sorry you only get 100 levels of Undo)

The Nunchuk control is now functional

The Zoom in a box cursor is now working

See the Help page for instructions

I made a lot of changes and it's getting quite complex so I expect to find a few rough edges if not bugs in this version

Here is version V0.99

The Nunchuk control is much improved

I made several incremental optimizations in the CSUB, now ~20% faster.

I took a first stab at changing the color mapping, I'm not the best person with colors but I think it looks better!

Hi ! Very cool ! I tried it. I had sometimes the feel my keys would be used several times... so is it possible that this is the strange key-repeat some experience with different keyboards ?

But the programm looks really cool. Well done ! I check your new version.

Cheers TweakerRay

Here is version V1.0

Now has a very BASIC file menu to allow Save/Load of parameter sets.

There are also some sample files included in the .zip file

I already have plans for an enhanced Version 2 but not this week!

Thanks TweakerRay!  Yes, there are some reported problems with the keyboard repeating.  I have only seen it happen a few times myself  It seems to happen mostly while zooming In when the rendering time is long.  If I can find a solution I will post an update.

Hi Carl,

With a bit of luck I'll be composing v0.3 of the Welcome Tape tomorrow.

- Are you still happy for this to be included ? - it seems to have advanced significantly since you first agreed and perhaps you'd prefer to distribute it standalone ?
- Are you happy for it to be included in its current state ? - there will be opportunity to update it in future versions.

Best wishes,

Tom

I'm starting to feel like one of those guys that keeps finding problems with the firmware!

1st the good news. The mandelbrottest version fixed the zoomin issue for me.

2nd, version 1.00 brought it back! I do like what you've done with the color though!!!

Also, in version 1.00, starting with a Wii Classic plugged in, causes the cursor to wander 'south' or to the bottom of the screen. Unplugging fixes...after restart.

Looking really good...especially if the final solution to the keyboard issue can be found!

Yes! You can include the Mandelbrot Explorer in the welcome tape.  I don't really care how it is distributed, I just hope someone enjoys it!  There are still some potential issues with keyboard control, worse on some systems than others.  I think we are nearing a solution.

Thanks, that's very generous of you. I'll see what I can do about making it happen tomorrow.

Thanks for the feedback Steve.  Now we just need to figure out what changes in the test version actually solved the issue!  I think we are getting close to a resolution!  

The Wii Classic Controller acts kinda like a Nunchuk when the device is first opened but unfortunately doesn't provide the same data.  I'll put in a check to make sure it's really a Nunchuk until I get the Classic fully working.

Ok Here is V1.1 of the Mandelbrot Explorer:

Added the fix for the keyboard repeat per feedback from yock1960

Added Wii Classic Controller basic functionality (not sure what to do with all the extra buttons yet.)

Added some error checking in the file menu.

Great stuff Carl.

If I can be picky then there are a couple of improvements that might make it integrate better with The Welcome Tape:

- "F" & "Q" on the intro/help page should open the File menu and Quit respectively instead of just acting as "any key to Continue".

- the key to exit from the File menu should be "B" for "Back", or anything other than "Q" which elsewhere always returns to The Welcome Tape menu.

You should also probably clear the keyboard buffer when exiting/entering the help screen, file menu, and graphical display so that any residual keypresses from the previous screen are ignored, i.e.
Do While Inkey$<>"" : Loop


Thanks again for allowing me to use this on The Welcome Tape.

Best wishes,

Tom

This may have been covered before, but I missed it. With no keyboard plugged in, just my laptop using the USB B connector, I had no response to keystrokes while running the program (the nunchuk worked well, but can't do everything).

I plugged in a USB keyboard to the CMM2 for the first time, and got behavior as expected from the keystrokes. Is this a known issue? Is there a way to have the program respond to keystrokes from a connected PC?

I believe this is a known problem with any program using KEYDOWN. As I understand it the issue is that a connected PC doesn't send keystrokes it sends ASCII characters via the serial console.

Good point lizby,  I had originally used the Inkey$ function for most of the keyboard commands,  I moved everything to use the Keydown due to some technical issues with the Inkey$ function not processing while the CSUB was doing it's calculations.  Then I ran into other issues due to the Keydown function not being buffered.

Now that I understand this better I should revisit using Inkey such that It can be used over the console connection.  Most of the commands are simple keystrokes that should work from the USB console connection.  The cursor keys may not process fast enough but it's worth testing.

These are good suggestions, I will incorporate into the next version.  I think I'll wait a few days in case there is more feedback or bug reports from users before I post a new version.

I haven't looked at all into how CMM2 input is handled, USB B or USB A connection, but does LOC help? Especially "#0 can be used which refers to the console's input buffer"
