i am working in a card which involves SPI communication between ADSP-BF531 and ADSP-BF533.when i perform SPI Master mode communication(Transmission) on BF531,i am not able to see the SPI clock on the pin. i am able to get the SPI clock if i run the code on BF533(with header file and ldf file modification ). >>>>>>>>>>> do you mean that the same SPI code wor

Hi, I am kind of new to this ADSP.... I am working on the ADSP BF533 EZ-kit lite example "Audio talk through" .....

Simply setting the ADSP-21369 AMICTLx register ACKEN bit adds 2 wait-states to reads and 3 wait-states to writes, on top of the software wait-states. I would expect no difference if the ACK input is set high, but there is a difference. Unlike other parts that allow either, neither, the logical AND or logical OR of sw/hw wait-states, the 2136x has software wait-states always enabled and ...

Hi everyone, i am a newbie in the field of DSP processors. The problem that i am facing pertains to transfering data from DSP processor to pic microcontroller through serial port. I am trying to send a continuous stream of data from the ADSP 2189M sport0 to PIC18C452 serial port synchronously. The clock is being generated by DSP processor. The problem is that the microcontroller misses the fir...

Hello All, I am using a ADSP-2181 EZ-KIT with Visual DSP++ 3.5 test drive version. When I set the flag (SET FL1;)it only stays set until I do the next "Step Into" and then it reset regardless of what the next line is. If I do a "Run to cursor" the flag will stay set until I do the next "Run to cursor" or "Step into". If I run the code in a "Simulator Session" the code works ok, but in a "EZ-KIT l...

Hello, I'm using the ADSP-21992 I'm having trouble with the DAC_Init. I'm not using the DAC in my program. In addition my code for the inititalisation. In that code you can see that DAC_Init is not ran through first, but in init_interrupts it is. When I remove '//' before DAC_Init, and delete DAC_Init in the init_interrupts, then I have other results, the same happens when I remove DAC_Init...

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 __________________________________________________

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

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...

Hi Gene, The crystal frequency is 25.000MHz on my ADSP-21262 board. I firstly made two boards for test now. Both run fine without capacitors connected to the crystal. I haven't tried other values yet. I think it has something to do with the board, wire length and width, chip and crystal packages...etc. You may need to try it out in your own condition. In my situation, ICE TEST can still be ...

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.

Hello, I've implemented filtering on the ADSP-21364 with a sampling rate of 48kHz. I use both analog and SPDIF interfaces. And in each case, if I enter, for example, coefficients of a low-pass filter with a cutoff frequency of 500Hz, the signal is filtered by a low-pass filter with a cutoff frequency of 1000Hz. So everything seems to be as the processor would read and write samples at ...
