Hi. thanks but, if you read my post i've posted that the selected component goes right to the dashboard, i'm asking just to gray out the double option that appears on the component bar, cause the "Add to System panel" is no longer needed, cause it's disabled. Of course if it can be easily done but t...

Hi Dave. Yes, Flowcode works like C does with a null terminator but also knows how long a string is - if there is no null before the end of the string then it will not go over the end. In your example with a non-null character in the 5th byte this will be sent too, but nothing else from the end of t...

Evening. There are a couple of changes in this release that will hopefully address two of the main issues raised on our forums. For those who do not want two panels If you wish to turn off the system panel and work on the 2D Dashboard panel only: In Menu->View->Global Options... ensure both 'Use das...

Hi. V6 uses a completely different file structure to v5, and this goes for the FCM files too. I have yet to add these to the converter, because whereas in v6 everything shares the same basic structure all files in v5 are different. As a work-around for now what I would suggest is import a FCF file f...

Hello. We have different technologies powering our website - phpBB, MediaWiki, hand-coded... One of the things we are looking into now we are adding more like this is tighter integration - I agree, you should only have to register once. It is something we are looking into anyway. Until then, I am gl...

Hi Jordy. In this version the Auto Day Of week calculation has been removed because this the algorithm used was to complex and eats up allot of program memory. especially for small uC this is a huge disadvantage. I don't know the details of your component, but if you create a property when it is dow...

Hi Acestu. Possibly, yes, but it all depends on the component you are creating. For example, if you have written a specific SPI interface component we could do a video on how to covert this component, but it would only be useful to a very select group of people. Also some people want their component...

Hi. Yes you can. It all depends on how you want to do it. You can write a flowchart that does the same as your custom C code, or just drop the C code into a C-code icon. We can help with either of these and how to define your component front end (what component macros can be called, etc) given more ...

No probs Brendan. BoostC and the launchers have had issues with virus scanners before now. I have changed the launchers a bit for the next patch but virus scanners can be pretty overzealous, so never know.

Cheers for letting us know.

Jonny

Hi. The patch with that fix will hopefully be out Wednesday. We put the release back until then for extended testing. If you really need something out the door before then then add a calculation icon, right click and select 'customize the C code' from the context menu. This will act as an alternate ...

Hi Brendan. I have the latest build available here and your PM'd program compiles fine for me. There have been quite a few fixes gone in to this build, so its possible one of them caught the issue, though I can't see anything in the logs directly relating to I2C. We are aiming to release the next pa...

Hi Brendan.

Can you post (or PM if needed) the fcfx program. Doesn't sound like there should be any issues with the program, but BoostC is pretty good at refusing to show any error messages just when you need them.

Jonny

Hi. OK, no probs. Flowcode 5 will behave in simulation the same as v6, which is to keep as like to C as it can. What a C compiler should do is perform any intermediate calculations as 'int', meaning multiplying two bytes will result in an integer. The optimisation may be 'clever' though (read 'wrong...

Hello. What version of Flowcode is this, and are you talking simulation or download? For example in simulation Flowcode 6 will always use 32-bit for its intermediate calculations. The compact A=(b*c)/d should always work OK in this case. Can you post a flowchart that shows your problem? Cheers, Jonny

Hi Wayne. You mean to be able to label each byte with a custom label? I don't know if there is enough space in the display to do that, but it may be possible in future releases to custom-label specific addresses, it is an interesting idea. It would have to be done manually though as there are too ma...

Hi Wayne. Good spot - I will remove that option for fixed buffers.

Jonny

Hi. We are in the process of testing now.

Once this build is tested and we are confident we hope to release probably Monday.

This build introduces aspect-ratio locking to components so dials and such can not exhibit this problem.

Jonny

Hello. I should have mentioned. In v6 we have 'casting' operators, string float, signed, unsigned. string variable Converts 'variable' to a string (it does not matter what type variable is signed variable Converts 'variable' to a signed integer unsigned variable Converts 'variable' to an unsigned in...

Hi Jordy. That error may be because the pins are not connected. The properties behave like pre-processor when converted to C. This means if you have a property called 'connection' and it is assigned to pin A 5 then what Flowcode does is take the line: connection = 1 And replace it with: $PORTA.5 = 1...

Evening Jordy. when I assign a true ore false statement to the corresponding output pin I get a some strange error message from Flowcode when I want to test it so you cannot use the output pins at this moment. What is the error you are getting? Perhaps if I can replicate that here then I can help? C...

Evening. In a calculation icon do:
Where temp-string is a string variable , text is the text to print and variable is the integer or float to convert.

That will put the contents in temp-string

Jonny

Hello. This will be fixed in the upcoming patch, apologies for this.

Jonny

Hello. We have not seen this before.

Can you give us details of your system and perhaps PM Dave who can walk you through some tests to discount?

Cheers,

Jonny

I hope this is more like what you are after:
You can disable the rulers and 'slide up' the toolbars if you wish.

Jonny

Thats strange. Not seen this before! You should not have to reinstall, regardless. Delete the registry key: CURRENT_USER\Software\MatrixMM\FlowCodeV6\Workspace\Serialize Could the panel have been docked somewhere hard to see? If you save the contents of the above key and PM me those, I can find out ...
