Hi Im using sharc 21060 . I need to sample my signal at a rate of 250Hz . What is much easier and accurate? Using the codec at 8k sample rate and taking every 32 sample ignoring the other 31 samples. or using a timer interrupt. Thanx yuv

Hello, I am designing a board based on 21065L SHARC. I have some clarification... During BOOT sequence, On reset, I find that BSO bit in SYSCON is not set(default state on reset) will this not prevent the assertion of #BMS ? because to assert B

Is there a way to declare and use circular buffers in C/C++ for the Sharc? I tried searching for some clues with no luck other than finding a few macros in macros.h. I remember someone telling me that these were buggy. I saw a few old posts on the subject but they didn't quite enligh

Dear Members, recently I installed VisualDSP++ 3.0 for Blackfin and Sharc. Before I had only VisualDSP++ 3.0 for 21xx. I done the procedure according the guide of ADI, but now they do not work properly. The next which I tried was that I uninstalled everithing and I i

I'm looking for a C source example that shows interrupt processing for an external device. In particular, how do I disable interrupts in C for a device so that I can safely manipulate related data structures (eg. buffer pointers)? Is there some way to save and restore the inte

Hi all, In the process of learning ADI's assembly language, I've stumbled on what I think is a bug in the simulator software that shipped with my EZ-KIT (I have release 3.3, version 2.30 of the software). In the SHARC 2106x user's guide, chapter 3.6.6 "Status Stack Save &

Has any one experienced partial short circuits apearing between adjacent pins on ADSP21061,2 devices. These shorts are around a few tens of ohms. On removing the faulty device from the pcb the fault disapears-probably due to heating the device

Hi i am workin on Sharc 21060 blacktip Ex board. i am facing a problem which is quite random in nature. In Visual DSP enviorment whenever i go in to debugger and loads my program on procesor, i expect the processor to halt at main(), as i have selcted it in options.

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

Hi, I'm a little bit confused about the correct setting of the SDRDIV register on a 21065L. On page 10-14 of the Sharc's User's Manual there ist given a formula to calculate the value for SDRDIV. Ther are explained some times but the example on the next page does

Good day Sirs, I need your help on setting up SHARC (ADSP-21160M) DMA chaining for interrupting the DSP core when a whole block of data has arrrived, not only sample based. I use a AD1881 AC'97 CODEC attached to SPORT1. BTW, ADDS-21160M EzKit Lite (the old one by

Hi DSP guru, I am programming for ADSP21061. The code was developed by other developer who left long time ago. I am trying to understand his code, but I don't have experience on DSP at all. The DSP is used as a slave that is listening to the command sent from the master Micro controller. These interface signals include IRQ0, dsp_data[31:0] SPR0I, etc. Accordin

I don't know how your fifo is connected -- but if it is connected in parallel, you just need to connect the fifo output lines (FIFO[11..0]) to the highest portion of the data bus -- that is D[31..20] if you use a Sharc -- and tie the lower end of the data bus to GND via a read-strobed bus
