Matrix user forums

I notice that you regularly post questions which can be easily answered by a simple session of clicking through Matrix Multimedia's website. Some pages you might want to spend quality time with are: Flowcode Examples Page http://www.matrixmultimedia.com/Flowcode_Examples.php Knowledge Exchange Artic...

It is a maze solving robot. Go to Matrix Multimedia's home page, type "buggy" in the search box, click "Search". There is only one hit and it is what you are looking for.

Hear, hear, for the search function. Presently I compile to C, then bring the C code up in an editor and search there. A search in Flowcode would be so much easier.

Chris,

I've never tried it, but I have read that each version of Flowcode can import code from the other versions. Got to File->Import then under file type choose "Flowcode for PIC files". In theory that should load it into your AVR version of Flowcode.

Cheers,
Jim

Yes, but unfortunately you have a 1 in 255 chance that this will fail. Since the EEPROM memory locations are initially random, the first location could well have 255 in it. If this is a project for yourself, no big deal. But if you are developing a commercial product you can expect a lot of failures...

Do a build to hex or to the chip and at the bottom of the listing displayed on the screen it will show memory used, both in number and percent, with the amount free, based upon the chip, also listed.

Chris, A couple questions about what you asked. First, when you say "integer variable" do you mean a variable declared as integer Vs byte, or just generically integer. Second, when say "When captured with a terminal program," do you mean that the results should be readable by a human, i.e. if the va...

Great. I'll be looking for it. And if you should decide to have beta users, I'd be glad to volunteer. Do I get a cigarette before the blindfold?

-Jim

As a new user myself, I too ran into this right away. The decision block can not do string functions. You may compare byte and int variables, but not string. In order to do a string comparison, first use a string function block with the compare$ macro, then a decision block, like this: results = com...

Thanks Steve. Just getting on the list is good. Certainly there are many other items for V4 which are of much greater importance.

And speaking of... Is there an updated ETA for V4? Will there be a beta?

Cheers,
Jim

Is there any way to change the default Target Chip when starting a new flowchart? If not, adding the default to the options dialog box would certain be a nice thing.

-Jim

Steve,

Regardless of the single step capability, a split/combine would be a great added tool. (That's what I've been manually doing.) The only issue I can see is you'll have to handle the conditions where a user selects a range with icons that can't be combined.

-Jim

And yes, your "exit" requirement could be done, but I can offer you a simpler way - why not just use a connection point to take you outside the loop? Steve, Ahhh, but that's a GOTO and we've been trained for years that GOTO's are a no-no. :lol: I understand your concerns about complicating things. ...

It would be most helpful if one could specify a variable to be automatically incremented by the loop processing. In a fantasy world, one would also be able to specify the initial and increment values as well. This would allow for the equivalent C Code for example: for (i=1;i<=10;++i) It seems that w...

Here, here! I agree heartily with Jan regarding the abilities to document Flowcode. As an "old geezer" of the programming world, I long ago learned to document, document, document. Now that my brain isn't as young as it once was, I find it even more difficult to remember the specific details of my o...

While working with the new gLCD component I decided I wanted to highlight with reverse video. No problem, I'll just flip the foreground and background colors from what the default colors are in the component properties. Hmmm, not so easy. The component properties use a 1 byte hex code, but the color...

The addition of the ability to add comments in the Calculation Component via '//' is a welcomed addition. It would be really nice to have the same capabilities within the String Manipulation Component as well.

Thanks,
-Jim

Ok, thanks. I'll go there. From a usability standpoint, a small blurb in a help file that says that would be good. As it is, the help button on the properties dialog boxes for these two components tried to load custom.hlp and custom2.hlp, which aren't there, leading users to think they are missing. ...

The ability to have multiple statements in a single Calculation or String Manipulation component is certainly nice, but it makes debugging difficult. Would it be possible to single step through each individual statement in a multi-statement component?

-Jim

While the act of loading an EEPROM component with random values can be a handy thing, it doesn't really simulate EEPROM. Since EEPROM is used to store values during power off, it would seem logical that Flowcode would preserve the EEPROM settings from on session to the next. I guess the FCF file wou...

In 3.4.7.48, if you use multiple lines of Macro Description (try using all 5) Flowcode does not allow enough space to display or print the entered lines of description.

-Jim

Ben,

The help files for the Custom and Custom2 components are also missing from 3.4.7.48. Perhaps somebody needs to review the 3.4.7.48 build and verify that everything that should be in it is.

Thanks,
Jim

Ben, Yes, but not really what I was thinking about. Without any kind of make facility, one would run the risk of updating a macro in a sub-program, then forgetting to export it and import it to the main program. A possible future enhancement would be that an individual Flowcode program had an option...

Ben,

Thanks for the quick response and help.

Jim

For ease of development and testing, I would like to create my Flowcode project of multiple individual Flowcode programs. For example, I would like the user configuration (end user configuration of product settings) to be a Flowcode program unto itself which would be called from the main program. Ba...
