CCS/TM4C1294NCPDT: tm4c1294NCPD

Part Number: TM4C1294NCPDT
Other Parts Discussed in Thread: CC3100, CC3100SDK, MSP430F5529

Tool/software: Code Composer Studio

Hi

I can not find any example for running in CCS (V8) :

- FreeRTOS

- CC3100 board

- TM4C1294 lunchpad board

I did not succeed to compile the MQTT example in above configuration

Where I can find documents that explain how to run the examples under CC3100 SDK ?

    Hi,

    From the CC3100 SDK import "getting_started_with_wlan_station" from "C:\ti\CC3100SDK_1.2.0\cc3100-sdk\platform\tiva-c-connected-launchpad\example_project_ccs\getting_started_with_wlan_station". Then port the MQTT code files from "C:\ti\CC3100SDK_1.2.0\cc3100-sdk\examples\mqtt_client". If you encounter any problem doing this ask help at Simplelink WiFi Forum.

    Another way is using the CC3100_http_server example program at Tivaware and then modify it to support MQTT. There is mqtt code library support at "C:\ti\TivaWare_C_Series-2.1.3.156\cc3100-sdk\netapps\mqtt"

    Had you noted that user stated his use of, 'FreeRTOS?'     The detail you've provided is excellent - but for the inclusion of (that) detail...

    Not all clients - always - seek to 'Lock themselves IN - to One and only One Vendor - forever!'

    cb1, I will just add more details to my last reply.

    The main.c code file from "C:\ti\CC3100SDK_1.2.0\cc3100-sdk\examples\mqtt_client" has the FreeRTOS.h include, see below.

    /* Standard includes */
#include <stdlib.h>
#include "simplelink.h"
#include "sl_common.h"

/* Free-RTOS includes */
#include "FreeRTOS.h"
#include "task.h"
#include "semphr.h"
#include "portmacro.h"
#include "osi.h"

#include <stdio.h>
#include <stdlib.h>
#include "cli_uart.h"

#include "sl_mqtt_client.h"
#include "mqtt_config.h"

    You need to Install the latest FreeRTOS version at C:\. Then at CCS Project set include and file search path for FreeRTOS.h which is located at "C:\FreeRTOSv9.0.0\FreeRTOS\Source\include".

    The latest CC3100 SDK 1.20 was released 2 years ago. So, I am not sure if it will readily work with the latest version of FreeRTOSv9.0.0 and Code Composer Studio v8. Any problem regarding this ask at SimpleLink WiFi Forum.

    Hi Markel,

    Thanks for offering this feedback, I think everything you said is on the right track except one small comment.

    Markel Robregado said:

    The latest SDK is actually 1.3 which was released in March: http://www.ti.com/tool/cc3100sdk

    I'll also add in for Micha's knowledge: as far as an immediate working example, the MSP430F5529 + CC3100 is the only 'ready made' example that has FreeRTOS + mqtt_client on CCSv8. So to get it working on TM4C will need the ports that Markel highlighted.

    Hi

    Thanks for the help.

    I have working stable project of:

    TM4C1294 + CC3100 + freertos.

    I will publish it in Github soon.

    I have working stable project

    May it be asked - how you have (properly) determined the project to be 'stable' - in so (very) short a time-frame?      Have all possible - challenging conditions - been first identified - and then properly exercised - and this over a (reasonable) test time-frame?

    It would be useful to others - if some 'standard' test for such an application exists - and which includes a, 'Full/Proper' exercise of 'ALL DEVICES' (w/in your project's (entire) CHAIN) - operating at/near their 'max' - for a test period deemed adequate...     Your Project's 'CHAIN' - proves, 'ONLY as Strong' as its 'WEAKEST LINK' - and that discovery (usually) is NOT - so quickly - uncovered...

    Do note - the fact that you've, 'made this effort' - and shared - is most commendable, thank you.      My objective in this writing - is to 'best insure' - that your project (really) IS Stable - so that you (and others) gain ALL of the, 'hoped for' benefits...

    1. I publish the project, so anyone can test it

    2. I used TI projects , and just combined the projects to one program

    3. I run test for 24 hours , 0 packet lost, so for me its stable

    4. I agree that TI should publish stanbdard test protocol.

    5. Ti must improve the examples, Trying to work with then take hours of integration. I did not find one document that explane "how" in simple description.

    thanks

    Thank you - your clear & quick response - along w/your project's sharing - is appreciated.  

    That said - as expected (due to the 'rapid-fire' award of, 'Project as Stable') your 'promotion' to, "Stable" proves (highly) non-standard.   

    Micha Nisani said:
    I publish the project, so anyone can test it

    In NO WAY - does the above suggest that the project IS stable.

    Micha Nisani said:
    I used vendor projects , and just combined the projects to one program

    Even should the vendor projects prove individually 'stable' - their 'combination' may create issues.      (This due to the "weakest link in the chain" effect - amplified by the 'combination.')

    Micha Nisani said:
    I run test for 24 hours , 0 packet lost, so for me its stable

    Again - how & why is this (un-described) test - and its relatively short test duration - adequate to promote as, "Stable?"     Somehow - any single individual's, 'judgment as stable' - which departs from normal/customary such measures - proves not, 'highly convincing.'

    It is suspected that 'stable' has (yet) to be proven - and that you found this, 'Combination of Projects' - suitable and adequate - for your current needs.    (Yet not 'stable' - in any classic or rigorous sense.)

    I Agree

    thanks for the importent remarks.

    Thank you - and do note - others (even small firms) may encounter your thread - and "Seize upon the (usual) definition of Stable!"      And - even though - especially though -  your unique combination (appears) to 'Work for You'  (thus far)  - it cannot rise to, "STABLE."

    I offer that caution in the 'defense of innocent others' - who may NOT YET have the many battle-scars - of we - LONG in the trenches!
