@rshankle- The difficulty with designs for an old device is not only part availability but ongoing support. It seem the old devices end up needed you to use the old tools which can be a problem if something doesn't work.
@78RPM- Interesting application. As to appropriate radios I think bandwidth and distance are the key elements. I have found that Microchip has a good range of solutions. Check them out if you have a chance.
@gordonmx, To find the frequency component of a vibration, yo have to do a Fast Fourier Transform. You will need a good 32-bit arithmetic unit and maybe a built-in signal processor. an MCU will require a lot of programming on your part. Better to get a signal processor on your device (not sure what device that might be).
Design 5 is a good example. A future class, or version of this class, digging deeper into determining when FPGA is a better solution would be nice: hardware cost, measuring performance bottlenecks, etc. Some MCUs are now including programmable state machines and complex timer logic that could solve a problem instead of a whole FPGA. Discussion on how to debug and test FPGA implementations would be nice, too.
@78RPM- Good point on medical devices. There is a difference between life support (like a pacemaker) and diagnostics equipment (blood pressure measurement). You need to look at the vendors infrmation to determine which they are applicable for.
@gordonmx- Finding the frequency component of the vibration could possibly be done with an MCU. Vibration is hopefully low frequency and I think an MCU could do it fine. If not, an external FPGA or an SoC FPGA could be a good target.
A step-by-step tutorial on how to get specific processors up and running would be useful. I realize there are almost an infinite number of options, but maybe a couple examples from each of the top few manufacturers would be useful. All the way from selecting the processor through to getting code running on the chip in an embedded application would be useful.
I prefer EDN and other articles, also white papers are good. In the past week I watched a horible webinar (Infineon IGBJT ) and a superb 2 hour webinar on hi speed PCB design by freescale. So it depends...
Biggest challenge is getting documentation which has a complete and accurate description of the product. For example the SmartFusion2 board has a SFP connector which is not included in the product description. It can be optical or electrical SFP.
Hi all -Audio is live! If you don't see the audio bar at the top of the screen, please refresh your browser. It may take a couple tries. When you see the audio bar, hit the play button. If you experience audio interruptions and are using IE, try using FF or Chrome as your browser. Many people experience issues with IE. Also, make sure your flash player is updated with the current version. Some companies block live audio streams, so if that is the case for your company, the class will be archived on this page immediately following the class and you can listen then. People don't experience any issues with the audio for the archived version.
The streaming audio player will appear on this web page when the show starts at 2 PM Eastern time today. Note however that some companies block live audio streams. If when the show starts you don't hear any audio, try refreshing your browser. If that doesn't work, try using Firefox or Google Chrome as your browser. Some users experience audio interruptions with IE. If that doesn't work, the class will be archived immediately following our live taping.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
