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, Has anyone translated the assembly code for Analog Devices EE191 "Implementing a Glueless UART Using the Sharc DSP SPorts" from it's ADSP-21161 to the newer ADSP-21262 and ADSP21363? The SPort interrupt registers changed with the part change. Before I re-wrote it, I thought I'd see if anyone had one they felt like sharing.

Hi, I've recently started up my 'ADSP21161N EZ-LITE' development kit. When I try to use the serial port the serial port interrupt is continously triggered and the program gets into a locked state. Why is the port triggering, there is nothing connected to it? The serial c

Hi all, I'm getting some unexpected results from the following setup, and perhaps someone has an idea why. I am simulating a 65L program. The simulator uses SPORTs streaming to read data from a file. The DMA reads a block of data (say 80 32bit words), then an inte

Hi, First of all I am sorry if you are receiving multiple copies of this mail. I am trying to program and communicate with CODEC AD73311AR on SPORT0. I have programmed the CODEC to work at 1.024MHz SClock and 32KHZ sampling frequency. I am using I2 and I3 for initializing SPORT0. I am attaching the code for CODEC and SPORTs initialization function. It is clear from the code that I have buffers...

I have the following setup: On the 21065L, the Transmit SPORT 0 is configured for I2S slavemode (external transmit frame syn), with two I2S lines connected to ports 0_A and 0_B, each line carrying a stereo signal (left and right channel). There seems to be no bit in the

I am having a problem with my ADSP 21161. I am using the serial port#1 for my input from Audio Precision. If I use 16-bit input format, I can pack the two channels (AP always outputs 2 channels together although I only need one) into 32-bit words and separate them in the SPORT interr

Hello all, the 65L has two serial ports, 0 and 1. Each serial port consist of two seperate data lines, A and B, making a total of four serial I/O lines. I seem to remember that when a serial port was operated in multichannel mode, it could not operate both A and B

Hi, I'm new to DSP programming - though I have experience in assembly programming of micro-controllers. I have a Analog Devices AD-21479 SHARC EZ-KIT, and I'm trying to program an audio pass-thru using the boards SPDIF In and OUT connectors. I'm using the on-chip SPDIF receiver to take my incoming SPDIF input stream from the SPDIF input socket, and feeding this on to the SPORT 0 serial in. Simi...

I am using 2189m EZ-kit which has a dual Analog Front End AD73322. It is used as a 2 channel ADC and DAC. Does anyone has any experience handling the program that communicate between AD73322 and DSP through SPORT? I tried the Talkthrough.asm demo program but it was only for 1 c

Hello everybody, I have an important question for you. does anybody know about the 90-pins connectors of the 21364 EZ-KIT LITE board. I need to use the PWM, SPORT and SPI but i didn't find any document about them. I hope they are accessible.
