Hi,
I found an FFT program written in Bascom 1.11.9.0 but not compiling in latest version.
http://mdiy.pl/wp-content/uploads/2009/12/spectrum_analyzer_v2_9d.rar
The error code is
Error : 200 Line : 242 .DEF not found [BETA []] , in File : D:\Program Files\Bascom\analizator.V2_9d_16x2.bas
Error : 369 Line : 281 Duplicate label name used by const or variable [SAMPLE_L] , in File : D:\Program Files\Bascom\analizator.V2_9d_16x2.bas
which apparently is related to
Code:
Dim Beta As Iram Byte

and a sub does have same name as a variable SAMPLE_L
Any suggestion how to get it running is very, very welcome.
Regards, Meister

(BASCOM-AVR version : 2.0.7.8 )

Just briefly looking at the code, I cannot see it used for any registers so remove
the Iram from the Dim
Code:
Dim Beta As Byte


Next rename the routine Sample_h to say Sample_hx
There is also a Gosub Sample_h, change to Gosub Sample_hx

Also so the same for Sample_l

Code:
Dim Div As Iram Integer At 16


You have to spend a while and fix some typos but the code will work for sure.In codes of this Author often variables are set in fixed locations. So You cannot simply adapt code from (another project) FREQmeter for ATtiny2313 to Atmega because, for example one variable is set At &H71 . Then You must open two datasheets and compare memory maps Smile

I get this analizator working like Include file for bigger project. You can watch this https://www.youtube.com/watch?v=P7805XtjeXU
But I wrote this for someone else and I don`t have hardware like TDA and filters for two ADC inputs when I test this code and making film.
So "No control" is displaying and response for freq will be better if You use dedicated filters.

Thanks for the answers.
@EDC, will your FFT Bascom code be available?

@EDC:
The Compiler complains:
Error : 200 Line : 101 .DEF not found [BETA []] , in File : analizator.bas
(coming from Dim Beta As Iram 'iram )
Replacing Iram by Byte gives same error.
Do you have suggestion on how to get it running? Thanks...

instead of the dim beta as iram byte, use the register name like R16
so code becomes :

R16 = I * K
r16=r16 and 31

Thanks, Mark.
I replaced all "Beta" by R16 but still get the error
Error : 200 Line : 101 .DEF not found [BETA []] , in File : analizator.bas
Line 101:
R16 = R16 And 31

Hi Mark,
strange thing is: after saving the changed include-file, no error any more.
Maybe not so strange because the included file always is loaded from disk and not from the IDE.
Thank you for your help.
I will try the code now.
Regards, Meister

Hello EDC,
thank you very much for posting the FFT code.
What I want to do finally is to get the phases of the spectrum components.
The comments in the file are in Polish and Google translate does not help too much.
Could you point out which arrays are are holding the real and imaginary parts of the spectrum so I could calculate the phases?
Thank you very much.
Regards, Meister

This code works so I never must deeply thinking how this is made Very Happy
Autor can explain this propabbly the best but I translate this to english myself so maybe this can be helpful.
Please write to the author for further clarification.

Thank you, EDC.
I will see now if I can find the lines corresponding to Re and Im part of the spectrum.
Best regards, Meister
