In that link there is the equation B(z). Is it sufficient to implement the filter FIR1(N,Wn) in c++?

I'd need the algorithm of matlab FIR.

I don't know the algorithm. With Matlab I use only this command: B = fir1(N,Wn) where N is the order and the Wn the cut-off frequency.

One question please: I implemented a low-pass filter FIR of 12th order and 5Hz cut-off frequency. I'd like to implement the same filter in c++. Can you suggest something?
Thank you

Thank you very much 2kaud! now it works correctly!

I'm trying to send encoded bytes (The codification with other code is made). I have understood that to stamp in the MFC application I must use "TRACE" and not "printf", but the real problem is that...

This is the complete code:


///////////////////////////////// Includes //////////////////////////////////

#include "stdafx.h"
#include "SerialPort.h"


/////////////////////////////////...

I'm trying but I don't know if it's correct, because i don't read any error when I compile, but none window appears to read the byte that I send...

Hi

Now I have obtained the correct packet byte to send after coding and CRC calculation. This is: "01 02 04 01 02 09 0c 10 02 06 12 01 01 13 01 01 49 f1 00"
Now I want to send it using the...

Yes, Thank you!

OK thank you. I didn't find http://msdn.microsoft.com/en-us/libr...(v=vs.80).aspx.
Why the compiler gives the follow error:
- syntax error: ';' before identifier ''^" ?

One fast question...
I'm implementing a 16bit CCITT CRC algorithm and I have found this sample:


unsigned int crc(unsigned char data)
{
static unsigned int crc;

crc = (unsigned...

Well! Thank you! This is a very good forum. I forgot to create
I have finished my second step with success: encoding and decoding the packet! And thanks to "printf" I have verified that all works...

there aren't any errors with this code.

Pardon...this is the code:


int main()
{
const unsigned char text[] = {0x01, 0x01, 0x01 , 0x00, 0x00, 0x00, 0x01, 0x00, 0x04, 0x01, 0x00};
unsigned char codify[200];

StuffData(text,...

This code show strange characters without errors:

I tried before to write!!! but it doesn't work (I have errors when it compiles or i read very strange characters) and for this reason I want to know if it is correct...

Ok I thank you very much.

the follow code ran with success, but I'd like to see the encoding packet. I have thought to use printf, is it correct?


int main()
{
const unsigned char...

OK thank you very much! Also if the problem is to send this packet: 0x01, 0x01, 0x01 , 0x00, 0x00, 0x00, 0x01, 0x00, 0x04, 0x01, 0x00. Not an Array of char.

I'm improving and now i'm trying and I'd like to estabilish a connection between 2 devices also if it's not very simple for me.

I'm reading and I'm trying many applications.

I have some problems...I'm a new programmer and all codes are not simple for me now. Are there some example code to understand how i can do it?
Thank you and I'm sorry.

Yes, but i don't understand well how i can do it.

I copied that from here: http://www.stuartcheshire.org/papers/COBSforSIGCOMM/ (at the end of page)

thank you very much Victor for your help! I'm a new programmer, but i'm improving and the communication between PC and device has been established also with C++ language. I discovered that I have...
