DSP Advice and motor driver compatibilty

Postby Yaro » Wed Sep 17, 2014 8:40 am

Hi all,

I want to ask if DSP are compatible with all motor drivers, starting from a low like a4988 to high cost drivers. Also, different drivers have different pulse duration, is a dsp configurable to be usable with this motor drivers? How much deep i can configurate dsp?

Where i can find a good list of all commercial dsp aviable? I'm looking for a list of dsp specifics with their pros and con and relative prices.

All dsp are able to do in the same work a cut and an engrave?

Thank you.

Most drivers work in the same way, so they are interchangeable, but, as you point out, they have different timing requirements. I don't know the answer to whether the timings are adjustable in the DSP (they should be), but I want to point out that the small driver chips (A4988, DRV8818 etc.) have very permissive timings -- they accept even very short step pulses (1 us) and require little set-up time for the direction pin (200 ns), so they will work with pretty much any controllers. It's the larger drivers that are more picky.

Thank you,

Can also someone advice me some dsp or just dsp names? I don't know a lot about dsp producers.

Ditto.... I'd like some recommendations on DSP's too.
