Hi one & all, I am working on the tms320vc5402 dsk with CCS v2.0. Hope everybody might be familiar with the demo example of audio signal input and output provided by TI in one of the folder (C:\ccs54x\examples\dsk5402\bios\audio) Similarly if i wish to run the same demo program=audio.out file (C:\ccs54x\examples\dsk5402\bios\audio\Debug) where in instead of the Hardware settings DIP switches (5,6-->up) (1,2,3,4,7,8-->down) Jumper settings JP1(2&3 connected) JP2(2&3 connected) JP3(2&3 connected) JP4(1&2 connected-default) parallel port cable and 5v adapter power supply mic i/p jack & speaker o/p --> one which normally used in communication applications compatible to oscilloscope. MCBSP1 channel *** No external devices interfaced like EMI, EPI,UART,JTAG)******** *************** Micinput i have taken from Function generator of amplitude 200mv peak to peak, frequency of 1000-3000Hz **************** Speaker output i have taken to oscilloscope to get back the original i/p signal which was initially tx through the parameters set for the function gen., **************** I request the group to help me out by giving suggestions or Source codes so as to fulfill my demo. By giving function generator i/p and oscilloscope o/p i had run the audio.out but it is unable to produce o/p. whereas the songs played is easily seen in the oscilloscope (variations in amp & freq) expecting positive reply at the earliest. Thanx & Bye for now Kumar |
