    OppaErich reacted to yyrkoon in RANT: Cloud of this, IoT of that . . .   
    So, am I the only one who is getting tired of hearing about "the cloud of this" or "the IoT of that" ?
     
    Networking has been around since when ? the 60's at least right. Then embedded devices date back to at minimum the '70's right ? So since when did this "rocket scientist" of a person decide to reinvent these ideas that have been around for tens of years. Known as "network connected storage", or network connected sensors" ?
     
    It's almost as bad as someone proclaiming in public "Hey, dont use your hand, there is this new product known as toilette paper . . ."
     
    Or am I worrying too much about this whole thing ? heh.

    It was cheaper to fly the thingies over the pond than to buy from a shop a few kms away, that was ironic methinks.

    Whilst that is a shame, I can see why. It must have been costing them loads. Back when you used to be able to get a $4.30 LaunchPad with free international shipping they must have been making a loss.

    @@dubnet @@yosh I saw that. It looks really interesting but I suspect it'll never actually get implanted. The size and location don't look ideal. However the real issue might be the silicone coating. The guy who fitted my implant was telling me about some issues with silicone coated neodymium magnets. Apparently with a bit of pressure the contents of the implant can rupture the silicone and it starts getting very nasty. What the guy should do is ensure that it will be possible to implant before going off designing something that'll never be used. I bet he won't though.
     
    My much smaller xNT tag is apparently fine even in an MRI. I did have a minor operation recently which required a general anaesthetic and I was asked if I had any metalwork, etc. implanted. I got some odd looks when I told them about this, but obviously it wasn't a problem.

    I don't use CCS but in general if the instruction pointer is past the last point where a local variable is used, the debugger information may be removed because the stack space or register has been reassigned to another purpose.

    OppaErich reacted to oPossum in Propeller open-sources P8X32A processor   
    No, not due to sales. Sales are fine at Parallax. They have been releasing a FPGA bitstream for the Propeller 2 that has been under development. The community really like being able to test a next gen chip before it became available. The release of a VHDL and bitstream for a Propeller 1 workalike will in no way harm sales of the Propeller chip. The FPGA is much more expensive then a propeller chip, and it would not be cost effective for a competitor to have an ASIC made. It is simply something they are doing for a few in the community that can hack away at the VHDL and do cool stuff.

    Smart meters are there entirely to suit the company that supplies them. The idea that consumers benefit is just marketing fluff. They save money on sending or someone to read the meter and they can cut off the supply remotely of you don't pay the bill.

    OppaErich got a reaction from RobG in Windows IoT program   
    I bought "Make: Getting started with the Intel Galileo" and had a quick glance. It's running Linux, GPIOs are Arduino 1.0 compatible programmed using the Arduino IDE. Example code was all .ino and one Python file, apparently setting up a simple HTTP server presenting the state of a button. Onboard flash holds Linux, micro SD crads up to 32GB are supported. It has an IOREF jumper to switch between 5V and 3V3 logic levels. There's also a jumper block to change the I2C addresses of the onboard peripherals. Book is aimed at beginners.

    Looks like Microsoft is getting started on IoT - so for the .NET programmers - this might be an interesting thing.  I signed up - apparently they're sending out free dev boards - https://www.windowsondevices.com/
    Could be a cool sensor hub for instance.

    Two of each arrived from Mouser Germany, they charged €3.20 per stick. 41xx runs at 24 MHz and 42xx at 48 MHz max. Needed to provide a LOT of personal information for registration at Cypress. Registration is needed to get to download the PSoC Creator IDE.
     
    A nice set of video tutorials enabled me to get the thing to blink in about an hour. Blinky in hardware No code involved, just drag'n'drop the hardware components to the project, alter the settings, wire up and assign pins. 
     
    The snap-off part is just an USB-Serial brigde. Windows 7 found the needed drivers on its own. The sticks come with a bootloader preloaded for programming, no debugging. A JTAG adapter for these is about $100.
     
    StellaLP for size comparison.
     

     
    Forget the Bootloadable and you have a nice $4 paper weight or buy a JTAG adapter !

    Long and hard day, but it was fun and well worth it. Gave out few LPs and almost all of the badges I had. 
    This year, more people knew about MSP430 and LP, and almost no "is this Arduino" questions.
     
    Just out of curiosity, I went to see what the Atmel Tech on Tour Mobile Trailer is all about.
    Mobile Trailer is a great idea, but I was not impressed with what I saw inside.
    It was way too dark inside, not much stuff inside, too many big screen TVs, high end products (bad choice for MF.)
    Free stuff for "qualified" visitors was very, very nice, but again, all high end.
     
    I wish TI did something like that, but more exciting (and with section for local BP makers.)

    That was the problem. temperature was declared AND initialized before main(). I've set it to 0.0 inside of main() and now it resides at 0x0200 and shows sane values.

    Is the posted code complete? Certainly placing functional statements such assignments to SYSCTL_RCGC1_R at functionfile level is not valid C, so perhaps that's inside a code block that was removed (or was not added as it needs to be).

    It's unusual in pre-C99 code to intersperse variable declarations like the one for tictac with code, so that warning may be a different issue.
