I'm not able to replicate the issue.

I see you have Keil uVision program opened, did you modify the FFT_demo example?

Can you please try to use already compiled binary located in binary directory?

Hi Miroslav,

your timely response helped us a lot !

I must say that you catch the right point and when I programmed it with binary, it worked 

But now it is not working with Tera-Terminal software at baud rate 115200 bps; 8 data bits; No parity; 1 stop bit; no hard flow control given in the readme.

I will look into this and update you in the post.

Once again, Thank you very much for your support !!

Thanks and Best Regards,

VK Verma

Please try 921600 baud.

Hi Miroslav,

As per suggestion it is working in 921600 baud rate. Then i think it is wrongly mentioned in ReadMe for 

115200 bps. 

Thanks for your immediate reply !

Please give me one more support (if possible).... can you kindly suggest some documents which will help us to understand FFT library functions given in this file, so that they can be modified and reused in other applications.

Thanks and Best Regards,

You are right, there is a mistake in the readme.txt file, we will fix it.

For the FFT functions you can check
