DSP Development Board Suggestions

[dreaquil]

Hi, I wanted to try some stuff on a DSP development board but there don't be too many boards with a decent amount of external circuitry for 50 to a 100 euro. Any recommendations please? I'd like it to have a jack input.

What are you going to use the DSP for? If you are using for automation and control, I know that TI has the C2000 Launchpads, which are DSPs masked as MCUs. I have the TI F28027 and it works very well. If you are looking for more powerful DSP processing, the C5505, C5515 and C5535 will give you extra power. All these kits can be used with Code Composer Studio for free.

Those look like exactly what I was looking for! I'm mainly going to be doing some stuff with audio so they work perfectly thanks!

For less than $50, an STM32F7 discovery board includes a fancy codec with 1/8" stereo in/out jacks, and packs a lot more DSP power than the platforms I learned on in school.  You'll have more development tool options, too, and if you've done ARM development before they also have the advantage of familiarity.

Of course, ARM Cortex M is not a real DSP.  If you'd like to program in assembly, I would strongly suggest a more traditional DSP architecture.  But if you're in C, although it pains me to say it, it doesn't matter so much.  I'm currently finishing a project where we needed to prototype some serious adaptive filters on a tight schedule.  Going with the Cortex M7 board was a no-brainer due to familiarity with the tools.

If you do go the ARM route, they provide a so-so DSP library as part of the CMSIS standard.  It is not particularly well optimized, nor does it include everything you might need, but it's there.

For audio you may also take a look at the following wiki:

From the options I mentioned above, the ezDSP 5535 and the ezDSP 5515 seem to be supported.

Hmm that looks like a beast of a board for a very good price.. any idea how well the software is supported in windows 10?
