    abecedarian reacted to Fred in Firmware Update Error   
    When I had both CCS 5 and 6 installed, I found that they could both insist that their version of the firmware was the right one. I found the easiest way to sort out FET firmware was to use the latest version of MSP Flasher.
     
    Be careful if you have an early version of that launchpad with the XMS430FR5969 chip. A FET firmware update can render it unable to communicate with this deprecated microcontroller. Later versions are fine.

    abecedarian reacted to enl in 220DC dropout   
    As a side note: I grab supplies from desktop computers on a regular basis. Modern ones generally provide 12V@5 to 15A (or more), as well as 5V@10A (or more) and 3.3V@10A (or more). They are often free from machines that have some other failure, such as hard drive, or so full of dust as to overheat the processor to failure.

    Joining the chorus in saying this is a really dangerous idea. Also, from a design standpoint, resistively dividing down this much voltage at 10A would require resistors that could dissipate a couple thousand watts. Not only is this very inefficient (in that the majority of your power is lost as heat) but a shorted resistor would put the mains voltage at the output. What is it that you are trying to power?

    abecedarian reacted to enl in Horowitz and Hill 3rd ed   
    There was a tremendous thump on my porch. The cat spun out hard, regained traction, and headed for under the couch. I opened the door to see the postman walking away and a large box sitting there. I opened it. A gold colored book. The third. has arrived. The cat reappeared, tail fur puffed out more than I have ever seen, sniffed the book, and promptly began dismemberment of the box.
     
    Then began the odyssey: reading the thing
     
    I have only done a partial look through at this time. It will take time. There are a LOT of changes. Much more a new book than a new edition, in many ways.
     
    Highlights:
     
    additional appendices and additions to the old ones. For example, a short intro to Spice. Nice for the students. It is correct, unlike many, many of the online tutorials. A short addition to the o'scope section for digital scopes.
     
    A decent (yes, this I read all of) chapter on microcontrollers. Not detail heavy. A good overview of use, architectures, some examples, a brief comparison guide. Pro: this now in the book. Con: not much to it. It is made up for by updates in the other digital electronics chapters. I will vote overall win, as WAY too broad an area, with too many options that change quickly, for much detail in a long-life, comprehensive text.
     
    New chapter on PLD's that looks good.
     
    Lots of updates to analog chapters.
     
    Missing is the section on construction techniques (unless it was blended into the main text somewhere). That was one of the parts I most often directed students to, as there really haven't been significant changes over the years. (protoboard, PC board, wire wrap, etc, though there have been changes in how frequently each is used with the dominance of surface mount components and easier PC board production compared to 20 years ago)
     
     
     
    Overall review/summary: it was worth the money to update. I have used 1st and 2nd ed.s since they came out as references for all of those things I don't use often, reference tables for part selection, and as references for students to look through. I would still recommend this to a student, in fact more than the outdated 2nd ed, with the caveat that this is NOT a barebones introduction to electricity. It has the target audience (advertising notwithstanding) of a student that has a basic understanding of DC circuits, math at the level of trig (or intro calculus), and basic physics concepts from an intro E&M  course.

    Update: We've decided to share the STL files for the Print-A-Bot ARM below - you can download them from our website here: http://roboteurs.com/collections/print-a-bot

    Hi Everyone,
     
    Great forum here at 43oh. We're new here, but was reached out on Twitter to share our new project / product we're working on. We're an education robotics startup in Canada (Hamilton, Ontario). 
     
    The product we've created is called the Print-A-Bot and it's a collection of 3D printed robots using the Launchpad MSP430. Our first model is the Print-A-Bot ARM.
     
     
    You can check it out at www.roboteurs.com
     
    We designed it in a way that you can print it yourself, even with a low resolution printer.
     
    We haven't posted the design files yet, but will soon.
     
    Please let us know what you think!
     
    Thanks!
     
    Justin

    8051 (and derivatives) will not die as long as a) there are applications for it 2) it is cheap iii) there are legacy applications where there is no reason to replace it/recode -..) manufacturers keep upgrading the peripherals to meet new needs
     
    That said, I haven't touched one in maybe 20 years. Or a PIC for a good 10.... I wasn't a great PIC fan when they hit the market, and still am not. Both architectures serve a purpose, and have done so for quite a few years, tho.

    abecedarian reacted to schen in How to rebuild library for MSP432?   
    I am using Energia 0015 with MSP432 LaunchPad. There are some missing functions in the library. I patched a few of them in the application code to get it to work. I would like to move the patches to the library. Unlike the Energia library for MSP430 or Tiva, the library does not get rebuild every time I hit verify or upload (which is a good thing). But I don't know how the library gets rebuild. Could someone explain it? Much appreciated.
