LAUNCHXL-CC1352P: Why pthread was used in all TI-RTOS examples

Jonathan Geronga

Part Number: LAUNCHXL-CC1352P

Hi Team,

We have a customer inquiry on why pthread was used in all TI-RTOS examples. Because as per the pthread docs pthread_create() APIs is used to create a thread. Then, pthread_join() APIs will join the two functions. So Application executes Two functions at a time (i mean simultaneously). But, our customer didn't see any pthread_join()API's in any applications(examples).

Please let me know you need more information from the customer.

Thanks!

Hi,

I sent it to a concerned engineer. We will get back to you ASAP. Please bear with us.

Thanks,

Hi Jonathan,

The majority of the examples use POSIX to allow most of the example code to be used on TI-RTOS or FreeRTOS. This makes it easier to maintain consistency across the examples.

We do ship examples that use the native TI-RTOS APIs:

all the kernel examples
portable native (you can diff the portable native against portable to see the differences)

Hi Todd,

Thanks for your support,

I have referred those examples. But I could not see the difference. can you plz differentiate.

Thank you,

Hi,

Here's a diff between the main_tirtos.c file in portable and portableNative. Note the portableNative ones uses the native TI-RTOS APIs instead of the POSIX APIs.

Hi Todd,

Thank you for the reply,

Yeah, I got the difference. Can you advise me like which one is best? portable or portableNative to use for SPI interface and Zigbee Communication.

The Zigbee examples use portableNative and I recommend that you use them as a reference.

It's really up to you to decide, but generally on the CC13xx and CC26xx devices, customers use the native TI-RTOS APIs to minimize footprint and slightly improve performance (due to the more stream-lined code paths). The main reason for using POSIX is portability or if the engineer team prefers using it.
