I've tried several of the audio examples included with CCS such as the CODEC and AUDIO projects, but I always get a loud annoying buzz! I tried various filters and this has only a slight effect. Does anyone know what is causing the buzz? |

I had a similar problem with my C5402 DSK and it turned out to be the
power supply. A 470uF capacitor directly across the 5V power in socket fixed the problem.

Programming G.723.1 to Flash Memory on DSKC5402 - temy sanjaya - Jun 30 9:02:00 2003
|
Dear, I have a project to program G.723.1 source code to Flash Memory on DSKC5402, then boot that program from Flash Memory. The size of the boot table is 87e7h (exceed 8000h), so i must used at least 2 extended program memory spaces (flash memory is mapped here). I've already used the secondary bootloader and using Flashburn Utility to program the flash. The question is, how to program the source code to that 2 extended program memory spaces. Should i divide the sections into 2 parts, how? And how to make the *.cmd file? Down here is the list of the command file for making the boot table that i used : audio.out -m1 -map audio-hex.map -o audio.hex -memwidth 16 -romwidth 16 -boot -bootorg 0x8000 -e 0x8075 -swwsr 0x7fff -bscr 0x8806 Any suggestion or help will be appreciated....thanks temy __________________________________ |
