Hi, 1-As I know in SPI mode there is not the feature to program FPER in McBSP. I want to read 16-bit samples every 125us in SPI mode. (it is compulsory). I want to use DMA and not add any checking or time consuming code to my project. 2- If my cpu internal clk is 120 MHz and the CLKGDV field of my SRGR is 8 bits, how can I use mcbsp(in SPI mode) with internal clk source and with 100KHz...

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

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

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...

Hello Everyone! We are having problems with T1/E1 streams on McBSP using DSK5402. Our application should extract data from one channel (64kbit/s) of E1 stream, do some signal processing, and resend that PCM samples. Though we've written our own code for this, we wanted to veri

Hi, I've been having a terrible time just trying to program a McBSP to produce any output on any line (I'm attempting to interface a 5416 with a TL320AD77 via a McBSP in SPI Master mode). It must be something very obvious... #define ADC_BSP hMcbsp1 MCBSP_st

Hello, everyone. I have a question about C54xx's McBSP specifically for C5409. When it is done with transmitting data, Does DX pin go into hi-Z state or stay in the last bit state waiting for the next frame sync? I know I can just hook up the scope and look, but thought I might get a quick

Hi, i've been trying to figure out how to interface the AIC23 codec, to the 5402 dsp. Can it really be true that i need to use one of the MCBSP for the control interface, and then use the other MCBSP for sending the digital audio data?

Hi, We are in the process of upgrading our DSP from C549 to C5409 and have a few questions that we need to sort out first before starting the design. i) Can the 5409 DMA transfer data from external memory between 8000h to FFFFh to the McBSP serial port (tx and rx)

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 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

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
