Hi Dan, I would try to separate register inits with commas: reg0 = val0, reg1 = val1, ... regn = valn; Usually (so far I've never seen a compiler that treat it differently) this would produce in-order assembly code even with optimization on.

Please excuse my rudimentary compiler knowledge. I am configuring a peripheral from C and it has a DMA feature, there are a few register loads, but I want to write to the register to start the DMA last. When I enable optimization using the #pragma, code is optimized such that the DMA is started before some of the other peripheral register loads are performed afterwords, resulting in fa...

I have installed visualdsp++ v4.0 and have registered my version. When i attempt to connect my tigersharc to the computer vis usd, xp detects the hardware, but it can't locate the driver to install the hardware! ahh driving me insane because obviously it won't install and therefore i can't get any code onto the board. Any one know how to solves this?

Dear Gene, I also had some problems using a crystal with that dsp, my solution was to use a clock oscillator instead (to pin 142, pin 143 xtal to ground through 0.1uF cap) , now the dsp boots up the 100% times, i know that for production boards is a complete diferent case because of cost issues but just wanted to let you know, cheers Sergio > From: "Gene-eng" > To:

Hi! Have you tried to run the Visual DSP configurator? , the software should be able to run your platform without any error, lets say the ICE Test with continuous scan, if you have done this and it works fine then you would like to read the jtag application notes from analog devices in order to be able to power-up your dsp correctly before you connect the emulator (i think some jumper...

Hi all, 1. Have anyone used the ADSP-BF537 STAMP Board for DSP development or application development ? 2. How suitable is the board for the development and debugging of video/audio codecs etc ? 3. Is there any known limitation of this board in terms of interfaces ? Thanks in advance, Krishna Kumar K __________________________________________________

Hi guys, I'm taking over a project done by a previous team, and there are still a few bits im having trouble with. Firstly, what does this statement do: __builtin_sysreg_read(__CCNT0); Does anyone know what the CCNT0 register does and how i can use this register. The data sheets don't really help. Is it used as some type of cycle counter? Second question: The code im looking at enable...

I. AUDIO DRIVER DESCRIPTION DMAR0 is generated once for the stereo pair of audio samples. The first read after from that address reads left channel, the second read reads right channel. Similarly, The first write after DMAR0 from that address writes left channel, the second write writes right channel. InitA.asm sets up the audio driver as the chained sequence of DMAs (all channel 0). ...

Hi all, I am porting a codec to ADSP-BF533 Ez-kit lite and visualDSP++ 4.0. What I am doing is: =20 1-Since my code is large, I mapped all of the data (including stack and heap) and code to external SDRAM and only frequently used modules to internal L1 SRAM (using LDF). 2-Caches are turned on to improve performance. 3-The encoder is reading an audio file (.wav) from PC using fr...

Rongxi, Please elaborate when you say "It failed to start if there were two 18pF capacitors connected between its crystal and ground." What crystal frequency and what capacitor values have you found to work without failure? We have been having problems with ADSP-21262's in production boards occasionally failing to boot (VDSP JTAG debugger can't even connect). We changed crystal cap...

Hello, I'm having a licese for the ADSP 21992 EZ-kit lite, but for some time, I just want to do some tests in simulator mode. Therefore I downloaded the Testdrive for 90 days. When I choose the session Simulator, I cannot choose my processor in the list. I'm using VisualDSP++3.5 with the upgrade. Can somedbody help me to use the simulator and the ADSP 21992? Thx, Reinhart
