ADI vs TI for Motor Control - dsp4motors - Oct 19 16:26:00 2003

Does anyone know what happened with DSP Motor Control Development at ADI? Is TI taking the lead with Motor Control and DSP? International Rectifier bought the ADI Motor Control development software from Amirix Systems Inc. in 2000. Now they have a high power module with a "TI" DSP. Fairchild also has a High Power Module with support for interfacing with a "TI" DSP. Is the TI DSP better for motor Control applications? It seemed like Analog Devices had put a lot of energy into DSP Motor Control development. The Datasheets were clear, the `on-board' peripheral devices were well designed, the code was easy to follow, the Application Notes were well thought out and extensive. ADI was presenting a series of WEB Broad casts about DSP and Motor Control, which just stopped. ADI is shifting towards our newer generation of "mixed-signal" parts, ADSP-2199x, but the application support does not seem as extensive for motor control. It seems like there was an unspoken split between the experienced Motor Control designer and the experienced software developer, each comfortable in their familiar worlds. ADI made it easy for a motor control designer to understand how understand and manipulate the DSP software with out loosing focus of the control loop. Is anyone developing an ADI - Power DSP Module like the IR (TI - DSP) Module?

An excellent question. I'm considering a new high-performance servo motor controller and will be looking once again at TI as a possible alternative to the 2199x line. I'd be interested in seeing others' findings as they look at the alternatives. Important features would be a flexible and powerful encoder interface and low-latency communication to host and peers.

Re: ADI vs TI for Motor Control - Hany Ferdinando - Oct 20 8:27:00 2003

in 2199x series, indeed there is Encoder Interface Unit (EIU). Now, I am learning to use that. Unfortunately, the manual is not clear enough, I guess. That's why, several days ago, I posted a question how to use that EIU. If anyone has used EIU before, please share your experience. regards, Hany Quoting Kenneth Porter <>: > --On Sunday, October 19, 2003 4:26 PM +0000 dsp4motors > <> wrote: > > > Does anyone know what happened with DSP Motor Control Development at > > ADI? > > Is TI taking the lead with Motor Control and DSP? > > An excellent question.

I've noticed a distinct shift on ADIs part away from supplying application source code and examples toward more partnering with third party vendors who develop and charge. I don't mind paying for complete packages but it would be nice if ADI would update some of their old ap notes for their latest processors. I have an old set of ADSP-2100 Applications manuals that I've been gleaning from but it would be nice to have some examples in C++ or for some of the newer processors.

We are using ADMC-401BST (AD2171 core) for several power applications, we are doing just fine and from our point of view AD has several advantages over TI, as speed and flexibility.

The 401 is a good chip, and we're using it in an existing design, but it looks like it's not recommended for new designs. I believe the 219xx series is intended to be the successor to the 401, what would have been the 501. It has the added benefit of JTAG debugging, eliminating the awkward need to burn a SPORT to get a debugger and boot interface.
