Nikhil Yadav

Part Number: CC3220S

I am having a wifi mote developed using cc3220s microcontroller. i have simplelink_cc32xx_sdk_7_10_00_13 but there is no example for ccs. can you please provide any basic examples for ccs using wifi in cc3220s microcontroller

Hi,

CC32xx SDK contains WiFi examples inside directory \examples\rtos\CC3220S_LAUNCHXL\demos\. There examples you can import into CCS. More training material you can find at SimpleLink Academy.

which compiler i have to select IAR, GCC and TI Clang compilers are available and i am using CCS IDE

Hi,

This depends on which compiler you want to use. Use IAR Embedded Workbench IDE is used you should select "IAR Compiler". Selecting for other compiler (GCC, Clang) depends on your preferences. Maybe Clang can be slightly highly preferred, but it is your choice.

Hi,

CC32xx SDK does not contain FreeRTOS. You need to install them separately. For more details see quick start guide for SDK.

what if i used TI-RTOS7 then also i have to install separately?

Hi,

No. TI-RTOS is TI product from this reason is part of SDK package.

Hi,

Please read messages shown at compiler output. It say exactly what is wrong - you not have connected Launchpad to our computer.

actually i have a customised wifimote which is based on cc3220s microcontroller and it is connected

and why it needs board to be connected for compiling the code

Hi,

According message above is your module NOT connected using XDS-110 or XDS-110 at LaunchPad.

why module has been connected for just compiling the code

Seems like the compilation was successful (i.e. ".out" file was created), but the default build-configuration (MCU+Image) tries to create also a "development" programmable image (.sli) which requires reading the MAC address of the connected device (development image is created for a specific device).

If you are using the CCS Debugger to load the image - you can ignore this error and continue to load the .out file.

If you want to flash the Image (to the serial flash/file-system) you need to connect the device.

you can change the build-configuration to "Debug" (right click the project -> Build Configuration -> set active) to avoid the creation of the programmable image,

why we are using RTOS in our applications?

0 Kobi Leibovitch over 1 year ago in reply to Nikhil Yadav

TI__Guru 63006 points

we have NORTOS examples in the SDK, but most of our customers use RTOS.

i asking sir what is the need and use of it in wifi

There are many threads (and inter-thread synchronization) used by our host software components (the simplelink driver, networking stacks such as mqtt and http and the sample applications).

Only limited amount of examples are supported by the NOROS environment.
