Hello all once again. from my previous post a few months ago, i have progressed my audio spectrum analyser ( this is for my Degree project). I am at the stage where i have got an audio signal sampled, buffered and started on my FFT routine. I have decided to use the Raddix 2 DIT routine. I have got the stage where i have calculated twiddle factors, bit reversal index and sampled the audio signa...

Hello, Below is the isr code snippet I took from valley tech PCI dsp firmware. We are using this to understand DSP/BIOS. We are able to generate interrupt from the HOST but it hangs at " SEM_ipost(&PciDmaDataAvail);" and never goes further. Any idea what might be the reason and does extern far keyword has any implication on this hang? "extern far SEM_Obj PciDmaDataAvail;" What does extern...

Hi. I'm new in DSP world but I program MCUs in C language for years. I bought DSK6713 from Digital Spectrum and I'm working with using tutorials and examples, knowing DSP behavior and environment. I know there are some daughter boards to expand functionality. I think this board is not enough to video/imaging real time processing but I found DSKEye daughter board, with Ciclone II and 5.2 Mpixels c...

Hello! I'm searching on net information of DSKeye. Now is difficult find in stock this daughter board for DSK6713, but BITEC told that they have some. I'm starting on DSP and I would like making some image processing on my starter kit DKS6713, that I bought recently. Do you recommend it?Do you know code examples for this board? Do you know another daughter board with camera for this starter kit...

Hello, I have a general question regarding the data bus for TMS320C6412. Please correct me if I am wrong. If I use any one of the EMIF memory space enable, ACE0....ACE3, I am accessing 64-bit DATA, is this correct? I am planning to design a board using TMS320C6412, I would like to send/receive 64 bit external data. I am not doing any memory interface, so I don't need any control signals. My ...

I am using TMS320C6412. We are using the PCI DSP driver code from valley technology as base to develop our DSP firmware. Currently we are evaluating valley tech. PCI DSP firmware. We found that even though we are setting HOSTSW interrupt from HOST we don't see interrupt getting handled in the DSP code. Any pointers on what might be going wrong? Or please let us know the required steps for the h...

Hi, I´m new in DSP programming. I´m trying to connect a C6727 DSP (master) with a CC2430EM transceiver (slave) through SPI in 4-lines with CS mode, on a custom board. With a very simple code that just sets the SPI registers and make a continuous transfer loop, the communication looks good on the scope. However, there is a delay between transfers of 200ms. I´m not using the WDELAY field of th...
