Does anyone have an example for using the KEYWDx (ADSP-21065L SHARC DSP User's Manual, page 9-75) functionality to trigger either a DMA or interrupt? Specifically, I have the following questions : 1) How would you set up the DMA to be triggered? 2) How would you set up the interrupt?

Hi Christopher, when I switched from IDDE Version 3.0 to 3.5, I experienced a similar problem, though on Sharc 21161. It was definitely caused by ADI's modification of the linker/loader stuff. I played a lot with modifying the ldf file and/or other settings but all failed. Frantically I just copied the file 161_prom.asm from Version 3.0 into

I have a 21065l ezkit and am reading the signal from both the left and right channels after grounding the inputs. The input to the codec is set to Line (both hardware and S/W) and I have noticed a significant offset on the right channel. The left channel gives me -25 to -30 or so, w

I am using an ADSP-21065L board of our own design connected via a 32-bit host port to a Motorola Coldfire processor. I've tested the host port communications both ways and it seems to work fine. I build the loader from the AD source supplied, only modifying the SYSCON register

The 21065l ezkit board uses the AD1819A audio codec. The AD1847 that your board has is not the same. I just noticed that the 1847 has no microphone input, only LINE or AUX. However, the multiplexer on the codec has to know where the signal is coming from, so my guess would be that somewher
