Hi! I implemented an "interprocessor communication" between several ADSP21065L with a SPORT in multichannel mode, that fails hazardous. There are 7 timeslots containing 14bits. One is the master (lets call him DSP1) and the other are slaves. In my testcase I elaborat

I'm trying to use the SHARC SPORT in multichannel mode and I'm having trouble understanding how to structure the code. I only get a couple of receive interrupts with my current code, although the transmitter seems to keep interrupting. Can anyone point me to code examples for multich

We have a system with a backplane with five slots for ADSP-21065L DSP's based custom cards. Each DSP card has SPORT 0 DR0A and DT0A tied together. TCLK0, RFS0, and the common DT signals are then each run through a 33ohm series to the backplane bus. The problem is that we are h

Hello, I have a question recarding the sport.h header file on the EZlite kit ADSP-2189m. If I use sport_start(0) or sport_write(0,0x55) I get an expression error. Is there anyone, that can tell me how to use this header file. An examples is also appreciated.

Hello,   I am using a ADSP21375 to read digital data from an ADC. I measured the frame sync to be about 1MHz but when I measure a 1kHz sine wave I get two cycles in 1000 samples. This means that my data has only a sample rate of 500kHz. It would be nice if somebody could help me with this problem.   This is my code:    #define SP_CLK_DIV 0x0004 //SPORT core clock divisor  #define SP_...

Hi, I've been trying to use a SHARC (21065 and 21262) SPORT as a SPI slave. I have observed that when I receive data, it is right shifted by a couple of bits (usually 3, but not always). If I send a "dummy byte", ie a byte in which the Sharc is not selected (selectio

I use ADSP2191 Sport0 in multichannel mode (H.100) with autobuffering DMA TFS/RFS external, SCLK external ... 8,192 mhz I need to enable disable and reenable again Rx. After boot and first sport setting up all goes o'k. But when I try to disable sport, writing zero in RSPEN and then enable it again RX intrrupts die. I also tried a procedure described in anomaly list ( Anomaly 8 ), it does...

Hi all, has any one implemented a small serial "network" between several 2181 type chips using the 2181-2189 Sport 0 Multichannel Capability. I'm looking for a bit of sample code. Also if 1 dsp is a master( supplies the framing ) and the rest slaves is it just a case of cor

Hi all I am trying now for a few days to send data to the SPORT of a 21369. I wish to be able to send a number of words, using framed mode with an externally generated clock and framesync. I receive data just fine, but for some reason I receive every transmitted word twice! A description of my setup: DSP: 21369 EZ-kit board. DAI header pin 3 connected to clock output of an FPGA ...

I have a strange problem occurring. I have a 21065L that does DMA through the sports audio in/ audio out, on interrupt. When buffer gets full, sport interrupts, I swap dma buffers for outgoing and ingoing, to a second outgoing and ingoing buffer, so that I can process the full data buffers. All works fine, except once in a while, failure is not peri
