How does a DMA synchronize to the first element of the McBSP? The McBSP will send events to the DMA on every element transfer, but how does the DMA synchronize to an EXTERNAL frame synch (and clock)? Should the McBSP frame interrupt be used to start the McBSP transmitter/reciever? Presently the DMA is started and subsequently the McBSP. The McBSP is started irrespective of the external frame...

Fellow C5510 users. I'm having trouble getting the DMA's to work in conjunction with the McBSP's. Here is what I'm doing. I'm using all the McBSP's and DMA's to transfer samples in and out of the McBSP's, each McBSP is connecte

I have an Mcbsp configured to operate as an SPI in clock stop mode. I have one DMA channel configured to write to the Mcbsp transmitter using the transmit sync event, and another DMA channel configured to read the Mcbsp receiver using the receive sync event. I have the Mcbsp set to o

Hi All, I am a new member to this group. I have a query, In C5501, McBSP as SPI for TDM bus is what I'm trying to understand. I want to know whether for C5501's McBSP as SPI can be used for TDM operation? I have referred TMS320VC5501 McBSP Ref Guide (SPRU592E). The document says for SPI mode configuration XFRLEN1 & RFRLEN1 bits of XCR1 set to '0' meaning we must use a trans...

Hi! I=B4ve a very strange DMA behaviour. I use a DMA to sent data from memory to the mcbsp transmit register=20 and another DMA to sent the received data from the mcbsp receive=20 register to memory. I use a circular buffer for the transmit register=20 as well as for the received data. The mcbsp uses the same frame sync=20 for receiving and transmitting and the transmit DMA uses the mcbsp=...

Dear All I'm using McBSP#0 of C5510 DSK. Sending out some 32bit data and receiving via the same port works as I predict. But... Changing port from "McBSP#0" to "McBSP#1" does not work...Why? In this condition Loop Back mode works and there is no problem but disabling DLB fails. ---Any help would be appreciated--

Hi All, I am working on DSK5510 and want to initialize the McBSP ports on it. McBSP1 for writing control data into the CODEC. I do not want to use CSL/BSL for writing to the McBSP registers. Just saw some example project dsk1_app.pjt in the example projects. It uses the some functions to write to the McBSP registers (like DSK5510_init(), Mc_BSP_Start()....) I want to have source code fo...

Dear group, McBsp receives L&R channel of audio. It sends out a REVT to DMA to enable DMA's transfer. It has worked well for a while. But when I require the DMA alwasy start from audio sample of left channel, I don't have any means to do that. McBsp don't have "left channel REVT", it sends REVT for each recieving word. I appreciate any input. Wei

Dear list, I am trying to make a circuit board with 2 codecs, I have two McBsps available for this purpose. I studied the schematics of 6713 DSK, Spectrum uses two McBsps for one AIC23, McBsp 1 for control interface to set up the AIC23, McBsp 2 for audio interface for exchanging digital audio. My problem becomes how to connect one AIC23 t

Hello, I am working on a FleXDS evaluation board of the DSP TMSC5509A from FleXDS. The board contains the three terminals McBSP's ports. To communicate with Windows hyperterminal, I use the software UART minidriver from the Texas Instrument DDK 1.20. The exemple of the Software UART provided in the DDK works well. But, in my project, I want to use two McBSP's ports. To test both McBSP's...

Hi, can anybody let me know the McBSP configuration when DLB mode is OFF. If I select DLB ON it works fine . Samething if I do external connection, (for testing purpose I have physically shorted the pins DX and DR , CLKX and CLKR, FSX and FSR of EVM5502 McBSP) it will not . Thanks in advance Nagananda Shet

Hi All, I'm using the McBSP's on the c5510 device and I'm having issues with the states of the SPCR registers, after I initialise the McBSP with the following commands: /* Start MCBSP1, Probe Comms IF, Sample Rate Gen. and Frame Sync */ MCBSP_start(hMcbsp1, MCBSP_SRGR_START | MCBSP_SRGR_FRAMESYNC, 0x300); /* Enable MCBSP1 transmit and receive */ MCBSP_start(hMcbsp1, MCBSP_XMIT_START |...

Hi All, I have a device that is sending synchronous data (clock & data) to my 5510 DSP. The clock is continuous and does not stop when the device is powered. I am using a McBSP in SPI Slave mode. I understand that I need to initially assert the FSR line so that the McBSP can begin receiving data. I assert the FSR line with a GPIO on the DSP. I correctly receive the first frame...

Hi, I'm having trouble performing a simple interface with the MCBSPs on the board. My main goal right now is just to write a value to a MCBSP and read the value back out. My main problem is although I initialize MCBSP for both transmit and receive with MCBSP_start(hMcbsp0, MCBSP_RCV_START | MCBSP_XMIT_START | MCBSP_SRGR_START| MCBSP_SRGR_FRAMESYNC, 0). After writing a value to hMcbsp0,...

Hi all, I work with Mcbsp port0 on dsk5510.when I send data by transmitter I see clock pulse on clkx0 (pin# 21) of P2 on dsk.but if I don't transmit data the clock pulse stop too. How I must configure the Mcbsp to always see clock pulse. Thanks.

I am a newbie to the DSk and to DSP programming in general. I was wondering if it was possible to set up the McBsp 0 and 1 as a master/slave to run a quick test? I have been trying to do this with no success and wondering if I am missing something. Here is my configuration: /* MCBSP_Config ConfigMaster - Master configuration*/ static MCBSP_Config ConfigMaster = { MCBSP_SPCR1_RMK( M...

How to configure receive interrupt to work nice in 5509a. If I configure MCBSP to produce interrupt when RRDY bit changes from 0 to 1 (SPCR1 bits 5-4 00b) interrupts keep coming all the time, even when there is nothing to receive. Any other bit combination doesn't generate an interrupt at all. When I use receiver polling mode it works ok. Polling mode loop: while (!MCBSP_rrdy(hMcbsp2)); ...

Hi all, I am working with DSK 5510 to interface it to camera module C3188. I need four pins to do the I2C controll job and something like that. But I still need 8 extra pins to do the parallel transmitt. It seems that there is not enough pins on McBSP. Can anybody give me any idea to solve this trouble?
