EK-TM4C1294XL: Getting started with FreeRTOS from TI examples

Sasha Gold

Part Number: EK-TM4C1294XL

Hello,

I'm attempting to try using FreeRTOS with the EK-TM4C1294XL dev kit. I'm following along with this TI documentation "Developing Basic Applications With FreeRTOS on TM4C MCUs":

https://www.ti.com/lit/an/spma085/spma085.pdf

I've downloaded the example projects at the provided link:

http://www.ti.com/lit/zip/spma085

I've imported the hello example project. When I attempt to build, it gives errors regarding not being able to open "drivers/rtos_hw_drivers/h", which makes sense because the documentation suggests you must add those files. But I can't find where they are located. Where should I be finding these files?

All help is welcome,

Regards

Hello Sasha,

The files are located under the Driver Files directory.

I read that too, but there isn't a Driver Files folder in TivaWare_C_Series-2.2.0.295. I also checked the previous TivaWare, 2.1.4.178, for good measure.

Where should I look for that directory?

Hello Sasha,

The Driver Files folder is in the spma085 software download for each individual LaunchPad, not TIvaWare. So look under EK-TM4C1294XL in spma085 and you will find the Driver Files folder.

Thank you, I found them and added them to TivaWare as per the instructions and was able to build the example project.

Perhaps this should be a new question, but now that I've accomplished the installation steps 2.1 and 2.2, I'm looking for information on using TivaWare and FreeRTOS in a new project, as opposed to an example project. The above mentioned documentation doesn't seem to include how to do that. Do you know where I could find such information?

Hello Sasha,

That really just comes down to making the right inclusions. If you were starting from scratch on a new project you'd have to include the proper TivaWare libraries and links to directories, and then do the same for FreeRTOS.

These are the includes for a FreeRTOS project:

For TivaWare libraries, you can read Section 5 of our TivaWare getting started guide: https://www.ti.com/lit/pdf/spmu373

I suspected as much, but confirmation is much appreciated. That screenshot is perfect and will surely save me time.

Thank you Ralph for your specific and succinct responses!
