[Air ex Machina] #03 CC3200 with CCStudio

nikil511

Downloaded CCStudio, after creating an account on TI

http://www.ti.com/tool/ccstudio

I am familiar with eclipse based IDEs (for java though), so I thought how hard can this be ?

well... took me an couple of hours to find my way, and understand just the basics.

 

I started doing random stuff (like always) but this time nothing worked :-) so had to follow carefully this excelent guide (thank you for that shabaz):

http://www.element14.com/community/groups/internet-of-things/blog/2014/10/17/cc3200-internet-on-a-chip-getting-started-guide-part-1

which also includes this guide:

http://www.ti.com/lit/ug/swru376a/swru376a.pdf

Everything went smoothly, and CCStudio works as it should.

I really like the debugger  + serial console, and I guess that's one of the differences with Energia.

In Energia you can not "freeze" running code, so the only way to debug stuff is to use the Serial.println()

In CCStudio you freeze execution at breakpoints and check all variable state, etc..

 

Furthermore I noticed that http related examples use the TI-RTOS (right?)

I hope an embedded RTOS will not make software development more complicated (than a super loop approach), then again I guess that's unavoidable when program becomes more complex. Will report back on that.

 

I have encounter a problem. I can not make to "out of the box demo" work 100% correct again. I can see the web site with the demo apps, but temperature value is NaN. It was working when I first received the board, and I want to make it work again, to understand the example, so I will look deeper into that and edit this post.

 

EDIT:

found more details on the sample programs:

http://processors.wiki.ti.com/index.php/CC32xx_SDK_Sample_Applications

so the problem I had with the out of the box application is solved.

I was flashing "httpserver" and not "oob". Once I had flashed "httpserver", with the android simplelink app, I could see an (offline) website same as oob, and demo apps were not working. When I flashed oob, everything worked correct.

    problem solved, was flashing the wrong sample app :-) (httpserver instead of oob)

    Hi Shabaz,

    yes, jumpers are the same. Let me rephrase, "out of the box demo" was working fine when I got the board, then I flashed various things, then flashed again "out of the box demo" and it's not working properly. It's not important, but just out of curiosity I am wondering what could be wrong. I will check again tomorrow, and edit the post.

    Thanks again for the thorough guide.

  • Hi Manolis,

     

    This is great, glad you're making progress with the CC3200.

    I didn't run the out-of-box demo (went straight to trying to upload code to it, hehe), but I'm wondering if the issue is jumper related, because the on-board sensors may be

    disconnect-able.

    The photos on my blog entry have the default as-shipped jumpers connected, just the Uniflash one moved as required. Does your board have the same jumpers connected (I notice J2 and J3

    are marked SDA/SCL so they will be relevant - presuming they disconnect/connect the sensors, although I didn't check the schematic).
