Hi All, I have been using TI DM642 processor along with a set of libraries that TI has provided. The following is the experiment that I did to understand the behavior of TI DSP and NDK library. Whenever signal "X" to DSP is raised from low to high, a HWI function is invoked in my program, which in turn will set signal "Y" high for 5 microseconds (this time is not a concern here) and s...

Actly we are doing a project DTMF detection by using this kit. We hav taken fft of the dtmf tone and the determined the position of all the row and column frequencies and also their magnitude. The row frequency and column frequency having largest magnitude will decide which key has been pressed. But after writing the program when we are running the program taking input from 'mic in' we are g...

Hi, I am working on the C6748 DSP to develop a simple denoising application using an FIR filter with 147 taps. I am using the DSP BIOS as well. The board is an OMAP L138 by PD LOGIC having a crystal of 24MHz. The idea is to read in 2 channel audio from the audio input port (a noisy sound from the computer) and filter the data from the channels separately and put them together again before sendi...

Hi, Can you point me to the FS package you use? I'd suggest to use formatted output call, like fprintf() or call sprintf() to write a formatted string to writebuf, then write() or fwrite() the buffer. I guess that file text mode is what you need, am I correct? Rgds, Andrew > Re: Writing Data to MMCSD Card > Posted by: "B S" m...@yahoo.com matlab_fft > Date: Thu Feb 21, 2013

Hi, How to maintain a real-time when time to fill a buffer is shorter than processing it ? I want to use PING PONG case to maintain real-time but don't understand how should I do it because in my application, time to fill the buffer is shorter than processing it. In this case, should I restrict HWI to trigger about the same time which is required to process it ? I would appreciate if you help...
