Function-component creation from C code

[Mantas]

Hi,

Would it be possible and how to implement the possibility to create new components, or functions directly from C code, and them have them as standard library, like for the example I did with the inverse sqrt() function? Instead of having them as macros? Or is this just a no brain'er?

Cheers,

Hi Mantas,

The Embedded Macro and Hidden Embedded Macro options in the Interface manager are basically for this very purpose and allows us to build components which either call existing C functions without any additional overhead or to call code e.g. to read or write to an array as used in the DSP components.

Hi Benj,

Sorry for the stupid question, but where do I find this Interface manager?

Hi Mantas,

I talk briefly about the interface manager in this vid.

More info can be found in the Wiki but I have some writing on this section still to do so I could try and add to this extra info in later today.

Hi. Dave has produced a video on the interface manager here:

Hi Gents,

Could you create a video of showing how to create a component, or a function specifically from C code? I know there is a supplementary section in the settings manager an others, but this is still mind boggling for me What if a C code function to call has a pointer in the parameter section...you know some more complicated functions implementation done by you in a video would be very interested to see.

Thanks in advance! You are doing an amazing job there!

Best regards,
Mantas

Hi Mantas. Yes, it would certainly be possible to do a video on this.

As far as pointers go, we get around that when using DLLs by using an array of 1 element, but all macros must conform to Flowcodes procedure-call standard, that is that every array is followed by its size, and the return type (if a string) is the final argument. This is easily fixed with a #define though:

#define FlowcodeFunc(arrayptr, arraylen) RealFunc(arrayptr)

I've wanted to do a video on embedded component macros for a bit, so see if there is time today now I know there is demand.

Cheers,

Hi Jonny,

I would really appreciate that! This would simplify a big part of my work were I need to convert C code to flowcode!

Because we moved buildings the audio equipment is tucked away somewhere, but I have scripted a video and hopefully can roll that out when the box with the microphone us uncovered.
