Hi, my development project uses two DSPs: The ADSP-21375 and the ADSP-21369. For both of them I've the evaluation boards here on my desk. On both DSPs I want to send my own audio data to the codec therefore, I used the blockthrough examples but wihtout success. My output data are stored in two floating point arrays: fLeft and fRight. Now let's look into the processBlock()-routine. How do I hav...

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 ...

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. ...

Hi Everybody, I have an ADSP-21364 EZKIT LITE, And I want to make an Amplitude (volume) meter application. So low volume signal no led lightning, hiw volume signal all leds lightning. I want to build it on Talkthru Analog IN-OUT example. I start to modify SPORTisr.asm, but it doesn't work and I cant move on. Can someone help me please? Here is modified SPORTisr from Analog In-Out(as...

Hello all; I recently tried to get EE-60 (218x UART.zip) running on the ADSP-2189M EZ-KIT Lite board with only partial luck. Does any one have a functional port of EE-60 over to the 2189M EZ-KIT? I'm running VisualDSP++3.5. Paul

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 ...

Hi I am using ADSP 21369 and using command line interface to build the project. I am getting the following link error(see below) when I tried using the UART example. It is due to the macro SRU2 defined in sru21369.h.

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?

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...

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, 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...

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 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); ...

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?

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...
