Hello... And Apologies

Recommended Posts

Hello C2K folks!

 

I have been spending a fair bit of time reading about the C2000, as I am selecting a micro for programmable power supply and motor control applications. Obviously I need to be able to process waveforms with DSP and/or other math and suitable libraries.

 

OK, I am now going to commit the unpardonable sin of asking why I should select C2000 over Cortex M4. And if Tiva is being crippled so as to not cannibalize C2000 market share, are competing ARM's likewise inadequate.

 

Friggin' ARM's taking over the universe...

 

OK, sorry about the question, but I'm honestly willing to be convinced that C2K is the true way.

 

Thanks all.

Mike

Welcome Mike,

The C2000 has alot more to offer for the motion control market than the ARM. High resolution PWMs, chopping capability etc - Multiple hardware stages before the pin gets hot. I also like the invaluable real time debugging ability of the C2000 which the ARMs do not offer.

Mike,

You're absolutely right to question the friggin ARM's taking over.  They are great general purpose devices, but the C2000 devices are tailored for real time control applications.  The core CPU in all of our devices is the C28x.  I often refer to it as a mini-DSP because it has MAC instructions as well as a Harvard architecture bus, that said we call it an MCU because it is just as easy to use.  Our higher end devices have floating point units, DMA, and extensions to the instruction set (through the use of accelerators) which speed up certain math operations.

 

As a group, C2000 is solely focused on digital real time control and if you look at the kits and libraries we supply it becomes perfectly clear.  We supply traditional DSP libraries for these devices (FIR, IIR, FFT, etc.) as well as application centric libraries (solar, digital power, motor control).  We have even recently come out with some devices that have our new sensorless-FOC BLDC control algorithms in ROM.  C2000 is a one stop shop when it comes to digital real time control!

 

If you have any specific questions let me know!

Wow. It does look like the Delfinos are way more capable than the M4's.

And the Piccolos are an incredible value for the price point.

 

I'm going to focus on the C2k's for my applications for now.

 

Have to pick a bagful of development hardware and get going...

The controlCARDs are nice ways of evaluating the different devices in your system.  We sell the matching DIMM connectors so you can easily integrate those in a test board.  Also, don't spend big bucks on a debugger.  The XDS100v2 (which is already on most of the controlCARDs) will do just about everything you could want and is <$100.
