Hi all, I am using a DMA channel with autoinitialization. I have a frame of 4 16-bit words. My question is how I have to configure the DMA and the McBSP in order to synchronize the DMA to the frame sync signal. The problem is that the McBSP gives an event every 16-bit wo

I want to create a continuous clock (set by the baud rate registers) and fsync from the MCBSP and im not sure what bits need to be set in the baud rate registers to make this work. I have tried and got the fsync working but not the clock. Can anyone help? Tim King CES Co

Hi, For DSK5416, If in the MCBSP configuration, the word length is setup as 32bits/word and frame length setup as 2 words/frame, sigle phase, The interrupt response is setup to response to each XRDY signal. So for each frame, how many interrupts will be evoked? I

Hello All, I am using C5409 for a audio application. When I configure McBSP with CPU interrupts(XINT0,RIN0) I am able to play audio properly. I want DMA to be implemented for processing the audio data. I have configured both McBSP and DMA0(syncd on Transmit Event) and D

     I haven't EVM and emluator because they are so expensive for a college student.I know CCS2.1 have many function to program.For example, I can use the File I/O and Probe point to simulate the I/O read or write.But I use them to simulate DMA, McBSP and HPI,I failed.Perhaps my me

hello all, I am using c5409 based board in the development environment. I have connected PCM3008 with McBSP of c5409. I have programmed the McBSP such that, Recevie/Transmit Frame Length is 2 words per frame and Receive/Transmit Word Length is 32-bits.

Can anybody point me to the document that talks about the MCBSP's and DMA? I understand that only some of the DMA channels are available to certain MCBSP's...but I can't find a document that talks about that. Thanks in advance. -Mike

I am using the TI sample code for the MCBSP described in their T1 interface book. I am getting receive interrupts for every frame, but no transmit interrupts. I am using MCBSP0 and DMA channels 0 and 1. Anybody have any good guesses of what I should

I'm having troubles getting the DMA and the BSP to syncronize with interrupts. In general I cannot get the DMA to fire an interrupt after a block transfer is complete. The interrupts are enabled in the IMR. I can enter my interrupt with the MCBSP running alone. I can also run my DMA in no sync mode. I can conduct one block transfer based on t

Hi, I'm trying to work out how to do this. My current idea is... 1. unpack 16 bit words into 8 bit words so the DMA can copy over each word correctly. 2. Setup the DMA, 16 bit transfers. 3. McBSP for SPI operation, XFRLEN1 = 4 (5 - 1), XWDLEN = 8bits. I can't actually test this out yet so I was hoping whether someone

I am currently working on the C54CST version of the DSP and am having issues with configuring a DMA channel. What I am trying to do is capture(recieve) the DATA coming in on MCBSP 0 and just simply store the data in memory to read it later (basically I am testing part of the functionality of the DMA). MCBSP 0 is connected to an ST-BUS device (TP3071 CODEC) and the clock and frame sync are

Hi, I've followed the directions in SPRA661 to implement a software UART using the McBSP port 0. I am using a C5416 device and modified the included assembly slightly to allow for using a far memory model. Things work okay for the most part, but I am experiencing parity and framing errors every now and then when transmitting to the DSP. Sometimes I can transmit 100 or more characters wi...

How hard is it to use an McBSP as an RS-232 serial port? I understand I would need a level converter, but how complicated is the software to write? Is there any free code from TI which will do this? -Mike

Dear all In 5416 DSP processor : I used MSBSP number 0 and 1 to get CODEC sound data by using DMA channel 4 and 5. Both DMAs are used to get data from mcbsp ports. Frame sync and clock signals are input to this DSP processor. But I have reset problem. When I reset the board I find that sometimes input data is correct and has no problem but some other times input data is not correct. and s...

Can anyone tell me the fastest way to sign extend a value in data memory? I need to sign extend every piece of data that comes in through the McBSP using the DMA on '5410. Thanks, Leigh Wells Electrical Engineer Acoustic Positioning Research

Hi, all. I'm setting up the DMA for use with the McBSP on the '5410. I have set it up similar to how it is illustrated in SPRU302 pg. 3-50. Using the emulator and DMA channel 1, the DRR1_1 gets loaded with data from an A/D I have implemented, but I can't get the data to move f

I am trying to do read and writes using the SPI mode on the MCBSP. I can see the correct signals (data, clk and fsx) for writes but for reads, clk toggles from 0 -> 1 and fsx toggles from 1->0 and then stays there, has anybody seen this ??? I am not using the DSK. Thanks

Hi there, I'm just implementing a DMA transfer in ABU Mode from the McBSP to internal Memory. Everything works correct, but - when I use DMA Channel 0 I was never able to get an IR from the DMA. I have tried the same (with the same code) for DMA chann
