hi We are using ADSP 21364 for our audio processing application.We are planning to use MAX3420E (USB Peripheral Controller with SPI Interface ) to interface with PC through serial peripheral interface of the ADSP 21364. Is it possible to use SPI interface for half duplex communication with MAX3420E regards saju

Does any know if an app note exists on interfacing an AD1955 DAC eval board to a ADSP-21369 SHARC Ezkit? I'm thinking of using I2S from the SHARC and connect to the AD1955 board through the PCM connector. Any ideas where someone might find sample code and hardware ideas for this? Thank you, -David

Hello, I am working on the ADSP EZ-kit Lite 21369. I am wondering how to make the board working as a stand alone system ? I could generate a .ldr file from the loader utility. But how can a load this file on the board that it works stand alone ? Shall I use the Tools/Flash Programmer in VDSP++ ? Or an other method ? Have anyone a clue to help me ? thanks a lot, A.

Hey, I am using the ADSP 21369 along with the plx NET2272 USB connection to the host. The software written by analog devices uses various interrupts and interrupt blocking in the critical regions. However I wanted to use this USB along with a ADC which also has interrupts to transfer data. These 2 programs are not compaitble and I am unable to understand the interrupt handling of t...

Dear all Lately i have been working on adsp processors. But firstly i was never given a good idea why do we prefer adsp processors to traditional processors that is our computer cpu? I believe speed is never a factor because now a days we have multi thread processors capable of running complex video games. So how come a adsp processor is unique than a normal cpu of our computer?

Hello! We're using SPORT with external frame sync, external SCLK. SPxTCR = 0x85E1, dma descriptor mode (and even just simple writes to SPx_TX). We need an early sync, but independent of setting LATFS we get late sync. Why?

Hi, I am using ADSP-21262 for my project which is active noise control. Until now, I never get good result from my system, and I suspect that maybe its because of the default sampling rate that is too fast that doesn't give enough processing time for the algorithm. I've also try picking every n-th sample and filtering it with a low pass filter but still, I couldn't get the desired result. ...

I'm doing tests with hardware "ADSP-21262 EZ-KIT LITE" and the software as "Block Based TalkThru (C)". I put in the function "BlockProcess" my algorithm. But I see that output from the algorithm introduced me take effect only on 2 / 3 of the output signal. I also annoying peak (spurious effect) between a block and another. Can not understand where is the anomaly. Can you help Maurizio ...

Does anyone know if there are internal pull-up or pull-down resistors on the programmable flag pins (PF7..PF0) for the 218x series of processors? If so, are they configurable? How do I program them? What state are they (high or low)? I'm trying write a single software build to run on two different hardware architectures. Both use an ADSP-2188M. On one architecture, the software is suppos...

I am using ADSP 21368 based custom board, I need to flash multiple applications (at different locations) on to the flash memory on my board and boot the processor from which ever location using some switching process. Flash writing part can be done. I want to know, how to make the processor, to boot from different locations of flash. Thanks in advance.

Hello, I am new in this area of DSP`s I am using ADSP21364 to process audio samples from the audio codec ADAU1361, so i have to connect them. I conncted them vie SPORT and SPI. But the SPI port of the codec is used only for writting to the codec`s registers. And i have to send a word from ADSP wich contens - chip address, sub address and data of the codec register. My question is - how to s...

Hi friends ADSP 2181 and BF533 are not compatible. ADSP2181 is a 5V logic(TTL) while BF533 is a 3.3V logic device. If i need to connect ADSP2181 sport to BF533 sport is it enough if i use a voltage divider for level shifting? If not which level shifter IC is ideal in this case? I need to level shift all 5 signals on ADSP2181 sport i.e DT,DR,TFS,RFS,SCK.

Hello! We're using SPORT in multichannel autobuffer mode, SCLK and TFS/RFS are generated externally. After some special signal becomes high (let's call it RESET) SCLK/TFS/RFS are masked and SPORT should be disabled by DSP. When RESET becomes low SPORT needs to be reenabled. But after reenabling SPORT we have some corrupted data at DT. And (as we suppose) because RESET is async with DSP ...
