C5000 with Stellaris/others [how to start: IDE, rol of the dsp...]

Daniel Rebollo

Hello!

I use stellaris to control SSD1289 LCD/touch and main program but i like to generate up to 100Mhz waveforms (sine, square, triangle, others) and i think the best solution is to use a dsp (dsp drives 16bit DAC), but i dont know.

In final project i make a PCB but now, to learn, i think "audio capacitive boosterpack" is good choice (i have one), are you agree?

So i have a lot of questions:

DSP use same CCS syntax as stellaris?

How i program DSP trough onboard "audio capacitive boosterpack" USB, or i need to use emulator xds100 of stellaris board?

In "audio capacitive boosterpack", why is needed to connect msp430? dsp cant do everything?

I read http://processors.wiki.ti.com/index.php/Category:C5000 and other pages in ti website but i cant find something like "noob guide" xd

Thanx

I cant say everything is clear until all works, but i think the following:

-DSP can be programmed in CCS in the same way as any launchpad.
-To program, it needs a JTAG
-ACTBP hasn't JTAG

now, i try to connect ACTBP with XDS100 (JTAG, taken in a c2000 piccolo launchpad: http://e2e.ti.com/support/dsp/c5000/f/109/t/170621.aspx ), when it works, i will learn how to communicate with stellaris through UART and if it is good choice or I²C/SPI or other are better (i used I²C but never UART).

The C5000 on the audio boosterpack cannot be programmed. It's been crippled.

In order to provide the patented MP3 feature to use on the audio boostpack for free, a secured version of C5535 with JTAG disabled is used.

But neither if i dont need mp3 decode? there is any way to program dsp on audio boosterpack? :( i wanted this boosterpack to learn DSP :(

I would recommend using the C5515 or C5535 eZdsp.

:( i order two audio boosterpacks, for my partner and i, to develop, because i take part of Texas Instruments European Analog Design Contest 2013... if I had known that I could not reprogram this dsp there would not order... :( :(
Why are JTAG header if there isnt any way to use them? the only way to use this board to develop is reflow another chip? is dangerous...

two days ago i bought C5505 eZdsp, because is the cheapest DSP develop platform, but is isnt as powerfull as c5535. When i have money could be bought c5535 board, but I'm sad because I wanted c5535 audio boosterpack to develop :(
