Dear list members, I have PAL video cameras and PAL TVs. As I know from www.blackfin.org, there is a Carsten Knop's code for both PAL video input and PAL video output for BF533 EZ-Kit Lite. Since neither her e-mail nor her web address is not active, I could not have found the code anywhere. (Moreover www.blackfin.org site is down by a virus for a long time.) If you have this code, ...

Hi everyone, Thanks first of all for your help so far, I now have a new challenge (although I don't think it's that challenging!) I need to pass my video input through some image processing and onto a screen. I can input video as a frame and see it on my PC attached to my Blackfin processor, but how do I get it from wherever it's stored to an external display attached to my EZ-KIT Lite b...

I have a quick question about the video applications in the latest Blackfin SDK. They seem to all be for 533s or 561s. I have a EZKIT-BF537 with the AV daughter-board. I was hoping someone would have an idea what issues I might have porting these, or what I should look for (or even if it's just a stupid idea in the first place). All suggestions most welcome. John

Hello out there, I just wondered whether anyone of you has already solved the problem I am currently facing. I want to implement a multi section biquad iir filter on a Blackfin DSP. The problem with the filter routines that are provided within VisualDSP are: iir_fr16(): ----------- The function normalizes the a0 coefficient to 1. Since a1 and a2 also must be 1 or less in fraction...

Hi Is there anyone have experience with Ez-KIT BF533 connected with Blackfin FPGA EZ-Extender. I try few days ago it seems work but very strange, sometimes, impossible to work with the two boards connected together. Each one is working correct when working alone. If anyone is working with these two boards connected together, could you explain if there is specific way to work (switc...

I hvae a problem with the original ADI example code IDCT for blackfin. If I write data to the input buffer for the DCT (example code from ADI) and call the r8x8dct routine, the result of the DCT is overwrite the input. If I call the IDCT function with these DCT results, the result of the IDCT must be the same for all 64 values (plus or minus one). But it is not the same! The greatest differen...

Hi! Actually in blackfin we are configuring the general i/o lines as input or output at a time but can't both.. Is there any chance to make them as both input and ouput at the same time.. Because, iam working in the video encoder in bf533 ezkit lite and iam working i2c protocol. there PF1 is SDATA after data sent by the SDATA when it is configured as ouput it has to sense the ACK sent ...

Hi, I'm Marko from DSP research group of Institut Teknologi Bandung Currently I'm tackling with the implementation of a statistical signal processing algorithm on Blackfin BF561EZ. I just started working with the machine thus, you can consider me as a newbie. In my work, the machine needs to handle calculations with real numbers. The problem is even the algorithm is successfully compiled, the m...

Hi, > > I'm doing a project to do 'real time adaptive feedback active noise cancellation' on blackfin 533 EZKIT LITE. > I am using FXLMS algorithm. May i know if the above mentioned application can be implemented using block processing? As most of the ANC is implemented using sample by sample processing. Is there any sample ANC C code for BF533 EZKIT LITE available? Thank you. Look

Hello All, I have developed a custom Board from Blackfin BF-561 processor. I am interfacing DSP with FPGA. I have interfaced the DSP to FPGA using EBIU Interface. I want to read the data from FPGA RAM though EBIU interface. I was able to successfully read the data from FPGA RAM using Core EBIU data transfer. But the read is quite slow, Hence I want to perform the DMA transfer...
