Hi! I am a new member at this group and the first time I work with DSP56F801. I would like to connect it through the JTAG port to parallel port of my PC. How can I do it? Could someone send me the squematics for it? Thanks and Peace! Yahoo! Messenger Nueva versi: Webcam, voz, y mucho m Gratis! |

At http://www.newmicros.com/ <http://www.newmicros.com/> you can buy
a JTAG-interface for USD 25: <http://www.newmicros.com/store/product_thumbnails/JTAG-Cable.jpg> JTAG interface cable for programming DSP board utilizing Small C or CodeWarrior. Or if you want to sponsor Motorola, you can buy it at Motorola: http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=DSPCOMMPARAL LEL <http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=DSPCOMMPARA LLEL> for USD 200 or try http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=PP-JTAG <http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=PP-JTAG> which is perhaps not compatible with CodeWarrior and flash_over_jtag.exe Kind regards, Wim de Haan Exendis B.V.

I am considering the '56F807 for an application to control 4 DC motors, using a position PID control loop for each motor, with encoder feedback. I would need to two additional quadrature decode channels. I would appreciate any comments/suggestions with regards to the suitability of the '56F807 for this application. |

It should be relatively simple to create the two additional quadrature
decoder channels in software. Each quadrature decoder channel would use two Timers in the same Quad Timer Module. To get the speed you need, you will have to use "Super Fast" interrupts, full details on how to do this is in my message "RE: [motoroladsp] Measuring PW using Quad Timer Captures" that I sent on Wednesday November 27, 2002, at 4:59am. If you also need to include the Index and Home signals, that is a bit more difficult, but still quite doable in my opinion. It becomes a bit trickier for Quad Timer C, because you don't have I/O pins for Timers C2 and C3, but two of the GPIO pins could be used for the Index and Home signals in this case. I hope this information is helpful to you, please let me know if you have any more questions.

Hi Mike, We are very seriously considering changing all our designs to use the new ColdFire MCF5282, not because of any problems with the DSP56F807 chip, but because there is no good development software available for it, only CodeWarrior. Each new release of CodeWarrior seems to have a greater quantity of bugs, and much more serious bugs, than the previous release. Sort of like buying software from Microsoft. At least with the MCF5282, you have other options. In all of our designs, the MCF5282 is a "drop-in" replacement for the DSP56F807, at almost exactly the same price, and with a huge memory size and performance increase. We estimate that if the MCF5282 had been available 3 years ago, and we had chosen it for our new designs, all of our new products would have been launched over 8 months ago. That translates into increased revenues and reduced development costs totalling well into the six-figure range. I am also a big fan of Motorola's processors, and have been designing them into new products for over 26 years. I was one of the first people in Canada to get one of the MEK6800D2 kits in 1976 (I still have it, and its documentation, at home). I have designed products using MC6802, MC68701, MC68302, and now DSP56F807 chips as the CPU. It was only my long and very positive prior experience with Motorola devices (analog as well as digital) that convinced me to spend huge amounts of extra time, for no additional pay, and which saved Motorola's (and Metrowerks') bacon here at PMC (and apparently at other companies as well, due to my postings on the motoroladsp discussion group). Yes, it is a small world! If you are ever in the Vancouver B.C. area, you should drop in here to see our facility. I would be pleased to show you around, and maybe we could go to a local pub for lunch and a beer (or 2 or 3). :-) Best Regards, Art -----Original Message----- From: Mike Lindsey [mailto:] Sent: Tuesday, December 03, 2002 5:37 PM To: Art Johnson Subject: RE: [motoroladsp] DSP56F807 and motor servo application Art, I appreciate your response to my post. I had not considered using the fast interrupts for quadrature decoding. After reading your post concerning the quality of the CodeWarrior tools for the DSP56800, I am starting to have doubts about staying with Motorola for my servo project. I have used Mot. processors almost exclusively for 20+ years, however I am not impressed with CodeWarrior for the 'HC908 family, and it sounds like CodeWarrior for the DSP56800 is even worse. Apparently you have developed a lot of code using the DSp56800 tools. Given the chance to re-evaluate your processor selection would you still choose the DSP56800? I took a look at the PMC web site and realized I am working on a project ( not the 4 axis servo ) to control a PMC pitch controller, installed on a Washington State Ferry. Small world!

I had used the external quadrature decoder in my MCU design. I also considered to use it in the DSP56F801 applications. Attached file shows how to do it. Hopefully its help.

Darren Yes, This circuit has the problem which you pointed when it is used in positioning control. I used it in speed control system, so I had no problem with this circuit. If you want to avoid vibration problem, I suggest to use a PLD or CPLD, such as Lattice 20V8 or Xilinx 9536, to create a external decoder. I like 9536 it faster and can create more than 2 decoders in single chip. But if do so, a high frequency clock source, I estimate rough 100K, must be fed in the circuit to detect edge change rather than level change.
