Finally have all hardware I think I need. Got the CC3200 talking to server. Needed to get the ISM band working to communicate to a receiver in the house to ring a doorbell and/or buzzer. Battled some issues this weekend getting the CC110L boosterpack to play nice with the CC3200 launchpad. Turns out it was just a ISM sensor I was testing for moisture was left on in the yard and was sending data at the same time occasionally. The CC3200 launchpad works well with a CC110L boosterpack attached.

With CCS Uniflash what is the difference between the delete button and the erase tickbox.

I was expecting that the delete button deletes a file from my configuration list (i.e. opposite to the add file function) but I see that when I click on delete it also attempts to delete the file from the CC3200 as well, which I thought was the erase tick box function. As such how does one go about amending a configuration file (e.g. I was attempting to modify the oob ucf file and only include the files I was using) without deleting the file already flashed on CC3200.

Hello!

I was struglling with CC3200 analog input ADC example. It was not working. Sometimes giving only erratic values, sometimes only zero ADC values. Only the timer bits increased as they should. Found a forum topic about this bug:

http://e2e.ti.com/support/wireless_connectivity/f/968/t/365450.aspx

http://e2e.ti.com/support/wireless_connectivity/f/968/p/354092/1243186.aspx#1243186

Need a line in while (forewer) loop uiIndex=0;

ADC on PIN_57 is not allowed by example. Why? It giving value around 1090 regardless if connected to GND or not.

ADC on pins PIN_58 and PIN_59 do not have resistors "dnp" on P3 header. (Actually resistors are on P1 header so one can connect signals there).

There is another strange thing. It ADC input is floating the voltage on it is 0.5 V. If pin_60 is tied to GND via 100k then voltage is 0.4 V.

Is there some pull-up on the pin that has to be additionally disabled?

I made a voltage divider using 100k and 1Meg. 0.1 uF cap at ADC input was necessary to prevent pickup.

I have changed example to a function that returns just 1 value read from CC3200 ADC. A delay was added between enabling ADC and readout allowing the input voltage to settle down. Without such delay the value was erratic.

----------------------------------------------------------------

float readADC(unsigned long uiAdcInputPin)

{ unsigned int uiChannel;

unsigned long ulSample;

//uiAdcInputPin=PIN_60;

PinTypeADC(uiAdcInputPin, 0xFF);

switch(uiAdcInputPin)

{

case PIN_58: {uiChannel = ADC_CH_1;}break;

case PIN_59: {uiChannel = ADC_CH_2;}break;

case PIN_60: {uiChannel = ADC_CH_3;}break;

default: break;

}

MAP_ADCChannelEnable(ADC_BASE, uiChannel);

MAP_ADCEnable(ADC_BASE);

MAP_UtilsDelay(800000);

if(MAP_ADCFIFOLvlGet(ADC_BASE, uiChannel))

{

ulSample = MAP_ADCFIFORead(ADC_BASE, uiChannel);

ulSample = (ulSample & 0x3ffc)>>2;

}

// UART_PRINT(" %d \n\r", ulSample);

return ulSample;

}

what is the part num of the boost regulator, if it is the same family as the ones used in the Battery Booster pack, then the same fix could be possible

See my review, it details the fix http://www.element14.com/community/roadTestReviews/1712

hope it helps

Hi!

I have a question about energy saving mode.

In my application the board could sleep for 5 min and then wake up to send data.

I am trying to put CC3200 in hibernate mode (Examples Sensor_Profile and Hib) to reach the advertisized 1 year running time from 2xAA.

If I measure current across jumper J12 it is 0.2 mA (decreases to 20uA with extra 100k pull resistors soldered to the serial flash chip).

However the current drawn from 2xAA battery connector in hibernate mode is 0.64 mA with J13 removed (and unsoldered PWR and RESET LEDs).

There is boost regulator 3.3V chip U8. I suspect it consuming this extra current. (Or I2C chips?)

What is the purpose of boost DC/DC 3V3 U8? Is it supplied with a preproduction CHIP having a bug on the LAUNCHXL needing external DC/DC.

Coil L4 belonging to ANA_2 pins on the demo board is not populated.

With 0.6 mA could expect ca 3 months from AA cells but 20 uA would be great to have if possible.

Greetings,

Janis.

Needed to implement a way to ring the doorbell inside the house in case phone is unavailable for alert. Been working on implementing ISM band radio to a receiver connected to the ring circuit in the house. Spent the week writing the code for the ISM. Currently have an CC110L boosterpack on the CC3200 dev kit communicating to another CC110L with MSP430 wired with a relay to simulate a push button. If the wiring becomes difficult, I will just have it drive a buzzer.

Hi Janis,

it is correct, CCS can only upload the binary to the SRAM. But for real application, you need to flash the binary to the external flash on the Launchpad using the UniFlash. Later during boot, this image will be again copied by the bootloader to the SRAM to be executed.

I have not found how to upload programm permanently from the CCS. It remains only untill a reset.

RE: Have a question for TI re: The Internet of the Backyard Challenge? Ask here!

Robert Peter Oakes — Fri, 29 Aug 2014 13:05:13 GMT

you can upload directly to the launchpad from CCS, does it work this way ?

Problem solved.

Lost half a day time on Uniflash.

I tried to add a new file to the project.

Needed to modify bin file used under sys/mcuimg.bin

In principle it is logical. That one just does not upload a progrsm file somewhere but to a already defined place.

Now can flash my programm and it executes from flash.

Hi, TI!

I got stuck with a problem permanently storing programm on LAUNCHXL.

I can build the project, debug it. Wi-Fi connect LED blinks and in serial console I can see text coming.

When I run Uniflash and select oob.bin file to upload, it is uploaded. There are some other files that are present /sys/macadd.bin But after I reset the board and remove SOP2 jumper the board does not seem to run (no LED is blinking)

If you don't have CCS6.x yo may need to upgrade to it for the CC3200 see this http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/348219.aspx

Also an SDK here along with some videos for training purposes http://www.ti.com/tool/cc3200sdk

So after adding all these repository features, which is really not necessary when experimenting and learning on ones own, I discovered the handiest feature on CSS yet!

This is the "history" tab which relates to any file you edit and save (it is found in bottom right quadrant). Gives you a list of each saved event. You can then back track with ease by clicking on a previous saved time.

Somewhere through my rumbling through the TI website info I found a MS Powerpoint file named "CCSv6-TipsAndTricks" which gave me the insight.

I will try to follow your example as I get into using the code composer software.

You are right, there are a lot of options to explore, but I will just try to get proficient enough to do the challenge.

Time will tell to see if I can learn enough in time.

I am by no means an expert but thought to share these (random) steps for others who like me are working with CCS for the first time.

Learnt the hard way in my rush to get going with the challenge but it now appears that a little more prep and priming is needed to get to know CCS. As such it is well worth the time to set up a repository or backup system on CCS. From what I saw it looks like CCS already has the "git" repository capability. Not sure if you need it but I downloaded git file management package first as this handles all the unique file management searches etc (http://git-scm.com/). I then used this to create my git folder of choice on my system through the git GUI (on windows) as it also creates the required .git file.

Then back to CCS. In top right hand corner of CCS you click on Open Perspective (also available through main menu: windows | open perspective | other) and select Git Repository Exploring. Here I selected "Add an Existing local Git Repository" as I had already created a new local git repository through "git GUI". Just browse and select required folder.

Then when you have created or imported a project folder for your code you just right click on the folder in Project Explorer and select Team | Share Project. Here you will have "Git" as an option. Select this and click next. Choose repository folder. You also have option to create a sub folder etc.

That should then allow you to "clone" and link or backup projects to the repository. There are also online options too which you can link to your local git repository. I tend to use https://bitbucket.org/ You have to sign up etc. Plenty help files available.

Maybe others can share tips too as I am sure this may not be very well explained or may have missed key points in explanation.

Just to answer the question myself now that I have done more reading and gone over what I had read before (amazing what you miss first time).

Seems that this project file link issue is well documented and requires a certain type of work method and perspective about what the CCS IDE is all about (takes a few days to finally step out and decide to bring in those favourite eclipse marketplace productivity tools into this IDE). For future reference document that I found quite informative was:

As I just lost a good few hours of good code I thought best to resolve by asking.

Surely this should work by default without manual amendment so assuming I am not doing something correctly or I forgot to amend some setting when installing. Basically this is what happens. I choose "Import Project", I browse and select one of the CC3200 SDK example folders residing in my TI main folder. I tick both tickbox options "auto import referenced projects..." and "copy projects into workspace". I then get a list of invalid project path warnings. Why?? Please help as want to avoid doing what I did previously as I will now explain.

At first I thought instead of resolving workspace path issue I would save time by just amending actual example in TI CC3200 SDK folder, and then at some stage copy files across. Of course as I am learning I soon needed to backtrack as made mistakes with coding in original folder. So wanted to keep amended code with errors. So I right clicked on project folder in CCS project explorer and selected copy (as wanted to keep this amended code) and then click paste and it created for me a "copy of ..." in project explorer. I checked folder properties and under resource it said location of this new project was in my workspace (I ignored path warnings). Little did I realise that all the files within this folder were still linked to the original CC3200 SDK folder (I only now can see that).

So when I reinstalled the CC3200 SDK to get clean copies of examples I also lost the "copy of" work as all I had was a workspace folder and not actual files within that folder. Live and learn as they say :-(

Registering at Plotly is free of charge for everyone. Limitation, I read somewhere, is that it would allow to store 50 plots.

Is there an simple HTTP POST example for CC3200? There is a GET function used in OOB example. Is there some example where POST is used? May be in Weather Example?

Would like to HTTP POST following data to Plotly:

http://107.21.214.199/clientresp "HTTP/1.1"

version=2.3&origin=plot&platform=arduino&un=janisalnis&key=p3r69ls929

&args=[{"x": ["2014-08-26 15:18:01"], "y": [25], "type": "scatter", "stream": {"maxpoints": 20}}]

&kwargs={"filename": "streaming API", "fileopt": "extend", "world_readable": true}

Alternative would be to use Arduino C code example for Plotly to compose a POST message.

BigG,

you can download the CC3200 SDK: SimpleLink Wi-Fi CC3200 Software Development Kit (SDK) - CC3200SDK - TI Software Folder, then after installing it, you can find the documentation for driverlib under cc3200-sdk\docs\CC3200-Peripheral_Driver_Library_User's_Guide.chm

When I downloaded the setup file it was just ccs_setup_win32 so I renamed it ccs_setup_win32.exe and it ran ok. It did popup with this warning first

I continued and it installed fine. I am running Windows 7, Sophos AV
