Hi All, I have a problem for initialize McBSP to interface with ST-BUS(4 channels); that is time slot miss-align, two slot are shifted. My McBSP is serviced by EDMA and I've verified that EDMA transfer from DRR is correct but transfer to DXR makes this pro

Hi, I have set my DMA of EVM 6201 to read 16 bit samples each time thru line in and sending out 16 bit thru line out,but my MCBSP...ie the bits 7,6,5 of XCR,RCR are set to 32 bit..if i change it to 16 bit i dont get any output.does anybody know the answer?how does the MCBSP re

Hi all, I`m newbie to DSPs and I`m using TMS320C6711DSK. I want to generate a serial signal, which has 80 bits at 1MHz every 250 uscs. I want to use timer1 to prompt the start of the signal, and McBSP with EDMA to generate the signal. I'm able to make it once configuring the EDMA and McBSP properly, but I can't make it periodically, the EDMA interrupt is not generated. How can I do it?? Is i...

Hi Everyone, After my audio data processing on DSK6713 i need to transmit the processed data serially to a Microcontoller through MCBSP. I have studied spra633b and have tried both sample codes (MCBSP in Serial port & GPIO mode) but i am facing following problems: 1. In Serial Port mode when i run the program, i am getting the error "Transmission Error" (althogh i have shorted DX1,DR1 ...

Hi! I want the DSP to interrupt each time an audio sample is ready to be received from the McBSP and each time an audio sample is ready to be transmitted. So I want to receive data from the AIC23 codec, process it, but service interrupts in between and play out audio through line out. How would I go about doing this? I have scanned through chapters in the CSL API reference about McBSP and ...

Dear All, I have been using external clock for MCBSP. FSX signal has been generated on every DXR2XSR shift. I have been interfacing McBSP with HI-15530. FSX has been generated but it has not been activating the encoder. Because we are applying FSX Pulse directly on Encoder Enable pin of HI-15530. I have measured Voltage level of FSX signal through Volt Meter. It was something round abou...

Hi All, I am using the DSK6455 as my development platform. I try use the EDMA to handle the data transfer via the MCBSP channel. I can transfer the data perfectly if I use polling which poll the transmit and receive ready flag of the MCBSP interface. I want to use the EDMA but not polling to handle the data transfer. My program do not work when I test it. The problem is that the EDMA co...

I have configured McBSP0 as a slave to talk to my external Master. I used 4 pins, CLK, SO, SI, and SS as frame sync for McBSP. I do not have any issue receving data from Master. However I am haveing some trouble in downloading data to Master. Seems losing data. I configure EDMA to trasfer data from McBSP receive register to a buffer in memory. However I Did not configure any EDMA channel for Tr...

Hi I am using C6713 and want to interface a UART. Doing so by using McBSP as GPIO. I have taken the code from the TI's SPRA633C document that describes how to use McBSP as a soft UART in GPIO mode. To test the code and verify if I am receiving correctly, I just put the code inside a while(1) loop inside main() as follows voide main(){ ----- ------ while (1){ Ua...

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...

Hello, I am using McBSP configured as a SPI slave to transfer data from C6713 to a computer with EDMA feeding 128 element frames into McBSP and EDMA transfer complete interrupts invoking new frame transfers. The problem is that during almost every frame the transfer stalls at some point resulting the rest of the received frame to be zeroes. The transfer recovers when the next frame boundary nor...

Hi, I am developing a new board utilizing TI's C6415 chip and H.110 Framer. I have some troubles with the McBSP port when the the serial port is running at 8M. Basically all the three McBSP ports connect to the local stream of the H.110 Framer, the serial port clock and frame is synchronized to the external clock and frame signal fr

hello everyone! I'm now doing a project focus on transmission of data thru mcbsp that controlled by edma.the project is based on the 'app_dsk' demo.in the demo project,it uses mcbsp2 in both receiving and transmitting,in my project I just use mcbsp0 to transmit,no receiving,the data for transmission is prepared in the program.I just configure the registers of mcbsp0 and edma as required,mcbsp...
