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 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 using the mcbsp to control a spi device. i have the following functions: unsigned char spi_Receive () { MCBSP_start(hMcbsp0,MCBSP_RCV_START|MCBSP_SRGR_START|MCBSP_SRGR_FRAMESYNC,MCBSP_\ SAMPLE_RATE_DELAY_DEFAULT); while (!MCBSP_rrdy(hMcbsp0)); //(****)

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

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)

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 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...

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

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 all, I have configured the McBSP #1 as GPIO (RRST_ = 0 RIOEN = 1). When I read the voltage on that pin (the pin is not connected, working with 5509 EVM from Spectrum Digital), I read 0 but the DSP read a logical 1 If I link the pin to the ground, the DSP sees a 0.

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?
