Hi, I'm looking for a DSP board with TMS320C64xx or c67xx. I need a board with small footprint. I need an access to the HPI , all McBSP ports , GPIO and external interrupts pins and MAC (TCP/IP). Thanks for helping Pini PS I want to connect the DSP HPI to an A2D converter. Can I use a flat cable (15-50cm) with a BUS transfer rate of 5-10Mhz. Should I use a line driver (...

hi all can anyone tell me what's the following CSL function have done hMcbsp1 = MCBSP_open(MCBSP_PORT1, MCBSP_OPEN_RESET); if I...

hi all can anyone tell me what's the following CSL function have done hMcbsp1 = MCBSP_open(MCBSP_PORT1, MCBSP_OPEN_RESET); if I use folowing code to reset MCBSP1 in C5509a , my program can not generate interrupt. SPCR1_1 = 0x0000; SPCR2_1 = 0x0000; but use MCBSP_open my program interrupt well. all the other code i have not use CSL function.

Hello! I'd like to ask advice of DSP gurus in my doubt. In our design we have TI's C6414 DSP on main board. This board has to communicate with multiple sub-boards of the instrument. We want to have bidirectional communication. At present we use DSP's McBSP in SPI mode and ARM9 MCU on sub-boards. Little circuitry allows addressing, i.e. its possible to select single slave for SPI master-to-slave...

Hello All, This is regarding the DMA Initialization Problem I am facing in C6416 DSP. I need to transfer 2 frames of 10 elements from DMA to...

Hello All, This is regarding the DMA Initialization Problem I am facing in C6416 DSP. I need to transfer 2 frames of 10 elements from DMA to Serial Port Transmit Register(DXR) and the Transmitter empty event from the Serial Port is the synchronization event for the DMA. The DMA is element synchronized, and as far as I understand, the end of Transfer interrupt should come as soon as the DM...

Hi I am using the TI DSP eZdspf2812 DSP as a waveform generator. It is interfaced with a microcontroller. Basically the DSP acts as an encoder, ie it accepts a finite number of bits (1s & 0s) from the microcontroller and generates a waveform corresponding to the bits. Is the GPIO good for this interface between the DSP & microcontroller? Also the waveform goes to a D/A converter. Is it bet...

hi every body, i am using 6713DSK for my project.i use AIC23 for sampling a 1khz sin wave and collect them in a buffer.i configured MCBSP for 32 bit one frame format.after sampling i shift 32 bits samples to right to just have 16 bits of left channel.then when i plot the collected samples in CCS it is not a 1khz sin wave.does anyone know what is my problem. i dont have mush time.please help me if...


McBSP as SPI slave

Hi All: I am trying to communicate between C5502 and an Atmel processor with ARM7 core. We want to do the communication using SPI protocol with ARM acting as SPI master and C5502 acting as Slave. In our design, the ARM asserts the slave-enable(SS) signal only once at the start of transmission of the frame and it stays active throughout the transmission of all words in a single frame. The...
