I use 5502. How can I synchronize data transmitted through two McBSP ports via DMA? Data from DX0 pin should be synchronised with data from DX1 pin. This is needed to implement so called "Blackfin interface" between AD9957 and 5502 DSP.

Hi all!, Again me. I've written an ISR that reads Int16 elements from McBSP1 (it's configured through the GUI config tool). It's started in main(). Nothing happens. It seems the ISR is never executed. 1. Which HWI object should be configured for the ISR? (I'm using

Hi I have an ADC connceted to one of the McBSPs on the 5510, and I use a DMA channel to transfer words (16 bit) from the data receive register to internal memory. The sample rate generator controls the frame and clock signal generation,and I use the McBSP receive sync event to

Hi, I'm trying to build the video system with framegraber and TI EVM board (C55 or C62). The framegraber must be on the PC PCI port and interface to EVM via serial port (McBsp). The debugging of DSP will bi via ISA JTAG. The question is how to interface between fra

Hello! I am trying to get McBSP1 on my C5509A to behave as an interrupt-driven SPI slave device. I am experienced with this DSP (using it for 1.5 years now), but this seemingly simple setup is stumping me. I would very much appreciate any help a DSP Related user could give me. **********Goal (For Debugging)********** - On each frame transmitted by the master (FSX low and 8-bits clocked out)...

Hi I am using DMA with ABIS mode of McBSP of C55x to update the masking patterns in R/XCERA/B. But the thing is that inspite of the fact that i have tied the sync event of DMA to ABIS sync events and enabled the element level syncronisation even then DMA is unable to load

Hi, I have used TMS320VC5510 DSK to connect with a RF module through SPI. I encounter a problem that using scope I can see the correct timing of transmit data, receive data, FSX, and CLKX. But after that RRDY in SPCR10 does not pulled high. More detail, I try to write a register in RF module and read it back, checking whether it is the same. I'm sure that in scope I see the writing did hap...

I am trying to set up the McBSP0 as a master connected to an Atmel AT45DB642D data flash chip and I cannot get things to work. In hooking up a logic analyzer I can see that I am getting a CLK and the data is transmitting on the DX line but I never read back anything. I get back nothing even when I do a simple command like reading the status register. I was wondering if anything is wrong with my...

I have a specific question about how the DMA transfers 16 bit data to on-chip memory (DARAM). I understand the DMA and data buss uses 24bit addressing. So why does the initial memory address need to be left shifted by 1? From certain examples (McBSP to DARAM) that I've seen, why does the memory buffer need to twice as big. For example, if have one ele

I am a newbie to the TI C55x DSP and I am trying to use the FlashBurn Porting kit to burn an AT45DB642D Atmel flash chip. I am using the DSK5510 example to start with that uses a different flash chip and I am having problems getting things to work. My flash chip is connected to the DSP through the McBSP so I have set the bootloader for a serial SPI EEPROM boot from McBSP0. I have modified the FB...

Hi All, I'm trying to understand how the McBSP1 (AIC23 Control) is set up for SPI mode in CCS example project dsk_app2.pjt. In this 3-wire configuration the sample rate generator takes the CPU clock (200MHz) and divides it by 100 to get a master SPI clock of 2MHz. To obtain the frame-sync signal, the 2 MHz signal is divided by 20 and has pulse duration of 1 CLKX cycle.

Hi all, I am trying to connect an SD Card to a 5509A via a McBSP configured for MMC operation using the MMC CSL. I can successfully read and write sectors from/to the SD Card, and retrieve the SD Card status registers, so I think my physical interface is ok. In order to increase my bandwidth, I'd like to utilise the DMA Controller to handle the transfers to/from the SD Card. Th...

Hi, I have configured McBSP1 pins DX1, DR1, FSX1, CLKX1 on DSK5509 as GPIO pins. In order to communication with external RF chip I needed to drive CLKX1 functioned as clock. It successfully worked by writing feild CLKXP in register PCR high and then low. However, the frequency of this clock is about 0.4MHz. Does there has any method to rise the clock frequency up to about 10MHz? I tried ch...

Dear Does C55x support ABU mode like C54x? If yes what is the related document from TI? If no, how can I convert my application working on C54x to application for C55x? What is the differencies between ABU mode and using DMA auto initialization for autobuffering of MCBSP's data? In my application I have three I/O devices which provide speech data streams for my software appli...

I have a project that requires 5510 dsk to control a spi equipment. > From the technical guide of 5510 DSK, I know that 5510 dsk's MCBSP has internal spi port. My question is how can I connect the DSK's 80 pin port to a specific spi euqipment? It seems that some kind of adapter is needed. Where can I find more information about such adapter? Thanks for ur help.
