    Although all the LaunchPads feature a programmer-debugger, sometimes an external one might be useful.
    Segger has just launched the J-Link EDU Mini, with all the software and expertise of Segger, priced at just USD18!

    I'm very happy with the larger Segger J-Link Edu priced at USD60.
    I've ordered one J-Link EDU Mini and plan to review it.

    Fred reacted to RobG in Products using MSP430   
    I went to Sears yesterday to get my new lawn mower and I got a free gift, Kenmore Alfie Voice-Controlled Intelligent Shopper.
    The regular price of Alfie is $49, but they are now on sale for $25. However, if you are SYW member and you spend more than $25, you get one for free (expires 7/1/17!) 
    BTW, I also found Alfie for $7.95 on Amazon (with free Prime shipping, even cheaper from other vendors.)
    What's the big deal about Alfie? Crack one open and you will find the following:
    CC3200R1 Single-Chip Wireless MCU (with W25Q32JV (32M-bit) serial Flash memory from Winbond and a chip antenna)
    TLV320AIC3100 Low-Power Audio Codec With Audio Processing and Mono Class-D Amplifier
    3.7V 500mAh LiPo battery
    12 WS2812B LEDs
    Other useful things are microphone, large speaker, 2 LEDs, 2 switches, and USB port
    In other words, IoT experimenter's treasure chest!
    Can't wait to hack that thing (there's what appears to be programming header on the board.)

    Good point. I just had a look and stumbled over the CC3220, CC3220S and CC3220SF. I found a single reference to the CC3220 on E2E which concluded with "you discuss unannounced product on public forum".
    https://e2e.ti.com/support/wireless_connectivity/simplelink_wifi_cc31xx_cc32xx/f/968/t/548741


    There is also reference to the CC3220S(F)-LAUNCHXL on Mouser and Octopart but nothing there. I'm sure this happened with the MSP432 Launchpad too.

    I had the opposite. Licence sent immediately but launchpad took 4 weeks to ship. If anything, it looks like CCS7 might not need a licence at all. That might explain why they're being given away so readily.

    Answering some of my own questions (for posterity):
     
    Turns out that all I need to do to port most TI-RTOS drivers to another OS is to provide an interface to five headers.  So that's good news for Energia-MT.
     
    Here's a link, describing more.  You can see the driver support matrix, but scroll down to the "Driver Ports" section to see the specific method for attacking a port job.  I tip my hat to TI, they did a nice thing, here.

    Olimex make a PIR sensor with a MSP430F2013 and based on a TI reference design. Might be worth taking a look at if you get to the "roll your own" stage. I once added a LDR to it and changed the code a bit to turn a light on in the bathroom at night when I went for a pee.

    I'd say go for a Saleae clone on eBay. Software wise use Sigrok or Saleae as your moral compass dictates.
     
    I'm happy with my Scanalogic one. Another option.

    I was thinking more of the <$10 eight channel clones. Definitely good enough for some UART debugging.
     
    I'm in the UK but found UK sellers shifting them from a UK warehouse. Obviously they're all from Shenzhen originally. (Hmmm. Just searched and there seems to be less around than there used to be, and all seem to ship from China now.)

    Fred got a reaction from farhan in I'm struggling with the CC3200   
    I've just started playing around with the CC3200 Launchpad as I'm also finding it tricky. I think it's definitely the CC3200 that's difficult as playing with the TM4C1294 Connected Launchpad and TI-RTOS beforehand wasn't too bad.
     
    Here are some things I seemed to have to find out the hard way. Please correct me if you know better I've got anything wrong.
     
    Flashing with CCS Uniflash
    Connect using CC3x Serial (UART) Interface, not Stellaris In-Circuit Debug Interface. The SOP jumper must be set to 2 You must power cycle the whole board if you change the jumper. Not just the reset button. You can set the WLAN profiles in Uniflash. No need to use the "SmartConfig" which I had problems with. Select the profiles tab and check the "Update" box. Enter details for Profile1, etc. /sys/mcuimg.bin is what's run when the board is powered up. Always this. Not the last debug session like on the MSP430 or TM4C.  
    Debugging
    Remove the SOP jumper if you've been flashing. Power cycle. Not just reset. The dubugger is "Stellaris In-Circuit Debug Interface" UART output is "CC3200LP Dual Port". Sometimes you can't start debugging if this is connected first. You can attach once debugging. Your debug session is temporary. On reset it'll run mcuimg.bin code again. Some examples use SSID defined with "#define SSID_NAME" (e.g. WLAN Station). Some use the config in flash (e.g. httpServer). Beware. Other
    Watch that jumper to select station or AP (on P58). Stuff will hang if you set it wrong. There's a new SimpleLink WiFi Starter Pro android app. A bit more usable, but it's still easy to screw up profile settings and get it to misbehave if you flashed anything other than the OOB code. I think I've got my head round it now. Probably. The documentation is there but not easy to find and digest. The TM4C is much easier if you have an ethernet cable nearby though!
     
    I have found examples that can be done with FreeRTOS or TI-RTOS. A bit of a pain to tweak things to compile, but if you follow the guides under SDK/docs/example you'll get there.
