    luke got a reaction from cubeberg in Energia MT / TI-RTOS support for other boards   
    Hi
     
    When can we expect Energia MT to support multithreading on other launchpads like CC3200 etc?

    luke got a reaction from Automate in ConnectedByTCP Flood Lights   
    I just received a bunch of wireless controlled floodlights from HomeDepot.  Just search though HD's site with "Connected TCP" for product info.   I got the starter kit with 2 A19 bulbs and a gateway plus I ordered 6 floods.  They work great although I wouldn't really describe their light color as soft white.  We'll see if I get used to it.   The A19 bulbs however look really great.
     
    You can control them using iOS, android or any web browser.  Doing some very preliminary research shows that the underlying tech is made by GreenWave Reality using NXP's JenNet-IP's IPv6 stack.
     
    All in all remarkably cheap solution for retro fitting scene control with individual light granularity.
     
    The only bummer is that they don't have a wall switch yet.  They have a remote (which I am sure is always going to be lost) and as I said you can use the iPhone etc., but I am afraid it may be cumbersome for non-tech savvy folks.  
     
    We (as in anyone but me ) need to come up with a MSP430 based touch pad wall switch to control this baby.
     
    Does anyone have any experience with NXP JenNet-IP?

    I ran into this problem the other day.  According to this post you need to explicitly invoke the float version of the log() function, logf().  It worked fine for me

    luke got a reaction from GeekDoc in First actual fried MSP430   
    Not sure how prevalent, sane or amorale this is but back in 1979 (not a typo) being a young software engineer (no EE at all) I was tasked with writing code to control some things for Chicago Transit Authority. The custom board was in early stages of development and had some shorts. The gave a scope, a meter and sail go find the shorts. After a day or two we all agreed it was not going to happen soon on this complex board and we were under a very tight time line. Since it was an early stage board we decided to use the "hydro test" (this was Ontario). We simply plugged it in the 120v and looked for the fireworks, I learned a lesson, sometimes brute force is the best solution.

    Happy to hear you got it all working.
    Next release will have the same version of the DLL so that you can switch from Windows <-> Mac without having to update the firmware.

    Hi Guys,
     
    The probe side is kind of taking a lot of time  ... Still designing the hardware, I am not a seasoned electronic engineer. I will probably have a booster pack around christmas time. In the meantime, attached is my last update to the main board.
      Will for sure keep this thread posted. Thank's for enquiring afe.zip

    Great project.  I was looking at power supply solutions last night.  Primarily I wanted a really simple 3.3V source for my CPU etc. derived from a high amp 12V power supply which would drive my LEDs, motors etc.  Normal LDOs get mighty hot when driven from 12V.  I looked at the switchers and didn't like having to add an inductor and several caps and resistors.  Then I discovered these drop in DC/DC converters for a reasonable price.  I ordered some to play with.

    I like your idea of using TI samples, but just wondering if you where aware of these parts and what you think of the idea of using them in this sort of situation?  Generally I only need high current 12V and low current 3.3V so 5V is not needed.

    A question about the standalone programmer issue please.
     
    I want to improve my board by adding a programming jumper.
    According to zeke's schema above, he hooks up the jumper to pins 10 and 11.
    Will this work with the G2452? I have seen advice suggesting pins 2 and 3 :?
     
    Also, is there freeware that will enable me to make schemas easily like zekes?
     
    Thanks for reading. KB

    luke reacted to Rickta59 in Would anyone be interested in a MSP430F5510 breakout   
    The least appealing thing about it, is that It really isn't specific to the msp430f5510. That board is just a pin break
    out for 48 pin QFP chips. No usb connector, no decoupling capacitor, no XTAL provision, no BSL connector, no reset
    button, no pullup resistor. There is nothing that makes it a break out board specific to the msp430f5510.
     
    The bigger problem I see with trying to sell something like is the competition from itead / seeedstudio /
    dorkbotpdx prototype pcb services. They all make it so inexpensive, it stifles any reason to do anything other
    than design your own custom board and have them manufacture it.
     
    I recently looked into making some boards at home. I don't have a laser printer, I don't have the chemicals, nor the
    raw copper clad boards. When you add up the cost of printing, chemicals, and the copper clad boards it only makes
    sense if you are building a different board every couple of days or you are trying to keep your design confidential.
     

    We are in a sad state when I can have something actually manufactured half way around the world, have it shipped
    here on a plane and get it delivered to my door step for less than it costs me to drive to a local store just to buy the
    materials. I live in the boonies so just driving to radio shack cost me more than $15.

    OK, so the advice I've been given is SPI and it makes sense. So I've ordered 250 of these B/W SPI displays, and will make a booster pack. But it takes about 3 months to get the displays delivered, so it'll take a while. I will also resell them to anyone who wants to buy them in bulk, and will try to get the store here to sell some also. By that time, I guess there'll be many other booster packs with screens. I'll have to redesign the board, and will probably put it on the same hardware SPI-pins as the RF Boosterpack, so it's compatible. See you later :-)
