Matrix user forums

I am interested in using the DSP component in V5, however not being an engineer I find it very difficult. Particularly interested in bandpass filter in the voice frequency range. Does anyone have an example they can post which I will use to learn from. I have a PIC 16F88 in mind. Will this be fast enough to handle bandpass filter function or is it to slow.
I have been watch the site for some time now, but no helpfull examples yet. I know what a bandpass filter does but I am not familiar with the terms used to setup the DSP component. So please be very explicit. I need this badly. Are there any you tube stuff on this or any matrix training videos, etc. Thanking you in advance.

Oh, am I posting this in the right place?

Hi Matrix team,

Is there going to be any explanation on how to use DSP how to use each componet
and any examples?

Hi Wayne,

This was meant to be released as an official article. I will chase it up at this end.

Hi Guys

I wanted to open an example with DSP but I get a message telling me that the 30f3014 is not available and that I must choose a substitute... First I would not know what could be a good substitute second aren't these chips available for download? I'm running flowcode 5.5.2.1profecional (am I missing something here? )

All the best

Hello Xavier,

The examples were all developed using Flowcode for dsPICs as these devices have the most power to do DSP type applications.

You can open the DSP example files into other variants of Flowcode but you will have to choose which target device you want to use from that variant's available targets.

Hi Benj

I was not notified of this message hence my very late response. As I have no idea as to what chip can be used with DSP can you tell me if there is a list available on these chips and how could I recognize one that has DSP?. Another thing that pops to mind is FlowCode v5.5 has DSP. I have looked long and hard on the forum to see if I could find an example using DSP but I have found non, could it not be possible to have a few examples using it ?

All the best all

Hello Xavier,

My understanding is that DSP is possible on almost any an 8 bit micro from "midrange" upward, but will be for less critical control applications, due to resolution and speed, not forgetting lack of the "dsp engine". The examples posted are for Flowcode V5 for dsPIC.

PIC micros specifically for DSP (digital signal processing) have the "ds" prefix (dsPIC) dsPIC30/33.
dsPIC30... series are 2.5-5.5V / 16 bit,
dsPIC33... series are 3.3V / 16 bit.
The PIC24 are general purpose 16 bit micros.

Hope this helps.

I just downloaded the free trial version of Flowcode 5 for dsPic and I am not able to load any of the DSP examples.
the program shuts down immediately. Their seems not to be a DSP module in the trial version. Is this correct or am I
missing something.

Hi,

No sorry the Flowcode v5 free doesnt have the DSP modules in it.

We hopefully have a new version of Flowcode coming out very soon and the free version of that will have the DSP libraries available to test.

Hi,

I upgrade Flowcode V5.3 ARM with last version. I see DSP component and I test this, but I have problem.
Gene is name of buffer.

How for controled parameters of FREQ with variables ?


Thank you very much
