Hi, Has anyone connected a host port to an isa bus? Any pointers? What I'd like to do is make myself a couple of pc/104 dsp cards, one with a 2191 and another with a 21161. I did a web search and found a couple of sharc based cards, but they were bi

I have a question about the TFS signal of an SPORT in an ADSP 21061: I set up the TFS of SPORT 1 as follows: Internally generated (ITFS = 1), data independent (DITFS = 1), late (LAFS = 1), active low (LTFS=1). When SPORT is enabled it works as expected

Hi, I am using VisualDSP tools(Release version 2.2) for the SHARC processors. I am completely new to ADSP tools. I am trying to experiment with data transfers through LinkPorts. When I tried with the LoopBack examples(both the core access and DMA access) given in the manual, I was

Hello all Has anybody ever experienced power-up problems with the 21065L Sharc? It is kind of a problem where the chip does not seem to "start" properly. The reset line does not help. It has to do with the 3.3V power - either the ramping of the 3.3V voltage or

Hi, Has anyone translated the assembly code for Analog Devices EE191 "Implementing a Glueless UART Using the Sharc DSP SPorts" from it's ADSP-21161 to the newer ADSP-21262 and ADSP21363? The SPort interrupt registers changed with the part change. Before I re-wrote it, I thought I'd see if anyone had one they felt like sharing.

Hi Albert, the bits SRRFH, SRRFL, SRD1H, SRD1L, SRD2H and SRD2L in the MODE1 register control alternate register select. Please note that the super-fast interrupt dispatcher (if you are using C) uses this feature too. As with any SHARC issue, read the manua

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 All, Does anyone know of examples for implementing Reflective Semaphores (a reflective semaphore exists in each DSPs internal memory and is accessed via aliased broadcast memory space) for the ADSP-21060 (I have a quad-SHARC system). I know the ADSP21-6X Users Manual has so

Hi, I am new to the DSP world. I need to develop an application on a board that interfaces Microprocessor to DSP. I am basically working on processing Audio signals from Microprocessor with DSP.I am just curious if I can pick an off-the-shelf board(SHARC Processor) running linux preferably that I can use for development.

Hi all, We recently started to work with the Ez-kit 21369 evaluation board from ADI. Compiling, Flashing and running algorithms works like a charme. BUT we suddenly destroyed 2 boards. And thus bought an antistatic mat with antistatic wrist band. Despite of lots of precaution playing with the board we still destroyed 3 of them after while... It seems that the processor still r...
