Hi all, I am developing a project based on Talkthru example for ADSP-214xx (21489 AD1939 C Block-Based Talkthru 48 or 96 kHz). While debugging the project I noticed strange behavior with Codecs Input/Output. The problem occurs if you HALT a running program on DSP and than restart it without loading / reloading / rebuilding the project. While looking for the problem, I also tested the default Ta...

Hello, I've trying to use the FFT Accelerator on a 21469 processor, everything is working fine in NOREPEAT mode but when I try to use the REPEAT mode I only get the two first interrupts (one for the input DMA and the other for the output DMA). My hardware is a ADSP-21469 EZ-Kit and the processor is a ENG version (thought that could be relevant). My original project is a VDK project but I modifie...

Problems with project in technical note EE-268 (Programming Asynchronous Sample Rate Converters on ADSP-2136x) on ADSP-21369. I started project ?SRC SPORT0 to SPORT1? on ADSP-21369 (dspblok? 21369zx). I have changed code for porting on ADSP21369 only by including files. But I have got output values in the negative and added ?DTYPE1 bit?

How can I get the twiddle and special twiddle factors for the FFT hardware accelerator in the ADSP-21469 processor?

Hello, I have measured a very high latency when trying to transmit a single quad word from the DSP to a Virtex5 FPGA on the other side. I am using the flag outputs as my indicators. I am raising one flag just before I write the quad word to the transmitter buffer (1): tempreg = __builtin_sysreg_read(__FLAGREG); tempreg |= FLAGREG_FLAG0_OUT; __builtin_sysreg_write(__FLAGREG, tempreg); ...

Hello. I have a ADSP-BF533 EZ-KIT. Does someone have an example in C how to write/read in/from the flash memory? I studied the example Flash Programmer from the installation CD but it's to complicated for me and I don't get it how it works. Thank you.

I'm having similar issues trying to simulate an ADSP-21369 mixed C++ and asm program using VisualDSP++ 4.5. When calling my assembly routine from a C++, the disassembly shows that the compiler translated this into a cjump. However, this action apparently is not pushing the PC return location onto the PC stack during the call. So when the assembly routine has completed and the program hits the...

Hi, I'm new working with DSPs of the Analog Devices, I have an ADSP 21262. How can I load a program in the chip? Do I need an extra circuitry to do this? I have an Sigma Delta Analog Digital Converter AD7716. I planning use this AD7716, but how can I interfacing dthe AD7716 with the ADSP 21262? If you can send me an circuit, It woul be better.

I hve a project on my hand. Originally, the project used AT91FR40162(ARM7TDMI) to connect to ADSP-2185's SPORT(DR1, DT1, SCLK1) via 3 pins (RXD1, TXD1, SCK1) operation on synchronous mode of USART. Data Rate = 480K bps. But now, we want to change the MCU to PIC18F8722(PIC). PIC uses 2 pins(CK1, DT1) when it operates on synchronous mode. Problem: 1. How does the PIC(2 pins) connect to the...

Hi everybody, I'm working in a speech project with the ADSP Bf-533 EZ-KIT LITE, and I have some problems with the sample rate. I need to get a slower sample rate in order to avoid aliasing in the input signal. I know that AD1836 only has two options (48Khz and 96Khz). I'm using the Serial Port to read the data and DMA to store the samples. How can I reduce the sample rate to, for example, 18Khz...

Hello everybody, I need to divide fract16 in my LMS algorithm and I use the div_s function in the ADSP-BF533 EZ-KIT Lite, but I have a problem: if the numbers are negative, the result of the division is 0. There is another function to divide fract16? I have thought to use the abs function and then add the negative sign to the numbers, but I think it has to be another easier solution. Than...

Dear Members, I have succesfully built my source code in Visual DSP++ 5.0 in simulation mode. Now I have to test it in emulation mode, and I use an ADSP TS201 EZ-KIT LITE board (two Tigersharc processors are on the board) and I can load my soure code to the board with the HPUSB-ICE Emulator. Now I'd like to insert breakpoints to my code, but it is not allowed.. If I try to insert original break...

Hi there: I have a design with ADSP21369 reading data from FIFO connected via AMI. The FIFO I am using comes without address bus. The full flag of FIFO is connected to the IREQ of ADSP to trigger the reading. I am not sure about its memory mapping. I guess I still need the Msx to select the memory. But how to mapping the memory if there's no address bus on FIFO and how can I control the data f...

Dear friends, I have some problems while experimenting with ADSP-21065 EZ-LAB kit. I have an old version, with RS-232 comms to PC and bundled Visual DSP 4 trial. I realize that it's rather outdated, but maybe somebody still remembers it.. I want to use a board standalone, so for experiment I'm trying to recompile one of provided examples as a boot image, specifically this is the Blink projec...
