Hello: I am writing some simple pass-thru-with gain code for the 56371. How should one setup the interrupt priority so that my external micro (connected to the 56371 I2C port) can from time to time change the gain registers in the 56371 without upsetting the interrupts on the I2S signal ports? Any direction or sample code would be greatly appreciated. Thank you in advance for your help...

Hello All, I'm trying to find out if the DSP56374 is "5 Volt" tolerant on the input EXtal pin. The DSP56371 is according to the UG - but I'm not sure if the DSP56374 is as I'd like to use an external XO. All other inputs are 5V tolerant - but I can't find anything on the clock. Does anybody know? brgrds, Paul

Hi guys, I recently bought a DSPAUDIOEVM motherboard with a DSP56721 daughter card because I need to make a new project based on this DSP. Although DSP563XX and DSP5672X are not recommended for new designs, I have a lot of code made for this family. I would be really grateful if someone could send me the source code of an audio passthru. (720passthru_FTF_20070619 I suppose). Besides, I'm lo...

Hi, I was wondering if anyone out there has successfully used the ASRC (asynchronous sample rate converter) for any of the dual core 567xx chips? If so, do you have some sample code that would shed some light on the intented use of this coprocessor? I should say that, following the manual and using the eval board, I have it in a quasi-working state using motherboard S/PDIF in/out on the ...

Dear folks, As you know, after a RESET, MS bit in the OMR is 0 by default, so the memory configuration consist of the following: 4K of program memory (0x0-0xFFF), 2K of X data and 2K of Y data. After RESET, I load the program memory by using the bootloader as usual. After that, my program sets the MS bit (bit 7) in the OMR in order to change the memory configuration to 2K of program memory (0x0...
