hi everybody, I tried to establish sport comm between adsp2181 and BF533. could not succeed. I tested separately both 2181 and BF and are working fine. I tried using loopback mode ( DT connected to DR of same processor) and it worked but when it comes to interfacing its not working. what could have gone wrong? First of all are the 2 processors compatible ( i mean can i really establis...

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_...

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 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 ...

Hello, We have a buffer of 1152*2 bytes,which will be filled often and which needs to be written to the DAC. We have configured the DAC for the sampling freq. of 48KHz. The DAC is in master mode. The transfers to the DAC are through SPORT. The document says that SPORT has an 8 word FIFO and interrupts the source of data until the FIFO is full. We have configured the DMA to interru...

I want to connect 3 BF533s processors together using the SPORT in TDM. I wanted to make sure my thoughts were correct regarding the connections. In order to receive and transmit among the processors do i connect all the DT0PRI and DR0PRI lines together? Also I assume the RSCLK0 and RFS0 are connected together as well. The TSCLK0 is not used and the TFS0 is a transmit valid flag, which doesn't ...

Hi, In my application SPORT is ruuning at 48KHz and i am sending a block of Data(12 samples in one frame), DMA is configured in descriptor mode, it counts 12 sample and transfer to CODEC which is also running at 48K HZ and after each sample tranfer it should generates an interrrput and goes in ISR routine to calculates samples. and loop keep on go

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

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
