Hi everyone, (I hope this question hasn't been asked elsewhere on this website. My apologies in case it has been.) TI has discontinued C6711 DSK in favour of C6713. Does someone know any place where I can buy C6711? I'll go for C6713 if its impossible to buy C6711. It's just that some of my friends/colleagues have C6711 and it would be easier for me to get started on this DSK. (I am almost a...

Hi all, I am programming with dsplibC67x.lib on C6713 DSK. As everyone knows, there are lots of bugs and special requirements in dsplibC67x v2.0. For example, function DSPF_sp_mat_mul(float *x,int r1,int c1,float *y,int c2,float *r) is used for matrix multiplication, but it needs r1, c1, c2 > 1. Unfortunately, I have to do a multiplication (Mx1)x(1xN). What can I do to handle this? (I know

Dear all, I'm sampling the audio signal through mic jack on C6713 board. The code is based on the example project "dsk_app". The audio can be played back from the speaker jack. However, when I tranform the signal in the buffer to double precision values, it seemed that (later) half of the data in the buffer has been truncked (all zeored). Is there any one can give me some advice to solve this...

I am using C6713 DSK . My question is can the stack be allocated in the external RAM?

Hello, I am using the C6713 DSP from TI. I'm trying to implement a timer. I use Timer1 by manually programming it (not inside the DSP-BIOS, but with a timer handle).

I enabled to use the dispatcher with "self" for the interrupt mask. ...

Hello All, I am trying to access asynchronous memory mapped devices on a C6713 DSK daughtercard.

According to the C6000 EMIF specification the fastest access should only take 2 cycles. So my C6713 is too slow b...
