Where will the link/tag to the zip download of source code be found on page?? Can you paste up the URL of where the ZIP can be downloaded from ? The main BRADA home page is very busy and I searched it looking for DIGI text and only found it in banner at top.
A: ISRs are a good way to maintain concurrency, yes, if properly managed. A state or RR without some control mechanism is indeed fragile if there are outside influences on the code (and there are almost always!).
HAHA about the free Freescale boards... Remember, Digi-Key is our sponsor. They sell Freescale as well as other products so we want to be sensitive to their part in that class. I give out tower boards in my face to face classes, but they cost $500-800 so the free class here is still a bargain even if you buy your own board (and please buy it from Digi-Key!).
Q: I have a question about interrupts - I always considered them to be a good choice for enforcing concurrency in a maintainable way. A tuned (for timing) state machine or RR construct is inherently fragile, is it not?
@78RPM - great question - each has a different price structure - some from device manufacturers are free, some are per development seat, some are per "product", some are per shipped device. Definitely something to understand before spending time on evaluation of a particular RTOS.
One stack, one program counter flow is non-tasking. Is just a superloop with code scheduling performed programmatically. Code must always return to top level thread and scheduling is bound by the longest execution subroutine.
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.
Good morning all!! Slides have been submitted to be posted. The code will be on my website by class time for you to download. Sorry about the system failure on the audio - the provider had a major failure! Of course! This has been a Murphy week!!!!
The company says it anticipates high-definition video for home security and other uses will be the next mature technology integrated into the IoT domain, hence the introduction of its MatrixCam devkit.
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
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.
