CC26xx foundation firmware examples?

Other Parts Discussed in Thread: CC2538, Z-STACK, CC3200, TIMAC

Is there any code examples as "../cc2538_foundation_firmware_1_0_1_0\driverlib\cc2538\examples" have for CC26xx? I downloaded http://www.ti.com/tool/cc26xxware

As I know, there is no such code example for cc26xxware.

I hope TI will provide more complete support for CC26xx soon.

I had asked TI local representative about this but it seems they don't have plan to provide this.

Hi,

26xxware (or driverlib) is not released as separate deliverable, but just for you to know, the 26xxware (or driverlib) is included as component in the TI-RTOS bundle

That is, driverlib abstraction layer is integrated as part of the driver middleware that TI-RTOS offers.

The TI-RTOS drivers make calls to 26xxware, and the driverlib source code can be found in ti/tirtos_simplelink_xx_xx_xx_xx/products

Hope this clarifies.

Thanks,

I think Sedar wants a basic example which can run on TI-RTOS that can test GPIO/SPI/I2C/PWM driver without Z-Stack or BLE stack. Is there any document show us how to create such a simple example?

That's correct. I think many new CC26xx users would appreciate to have such basic SW examples.

PIN, I2C, SPI and UART middleware drivers are released integrated with TI-RTOS. PWM is missing but the CC3200 PWM driver can be a good starting point.
Please check TI-RTOS driver runtime API document from the overview HTML document.
Please also check C:\ti\tirtos_simplelink_X_xx_xx_xx\tirtos_simplelink_X_xx_xx_xx_examples\IAR
The latest TI-RTOS release comes with examples of i2c, pin, and uart examples of how to use those middleware drivers.
Thanks,

Cool! I didn't figure out it is already there. Thanks.

It seems like one needs to directly access the registers by using CC26xxware in order to manipulate the DIOs on Contiki, as there is no generic GPIO implementation for CC26xx. In that sense, it would be time efficient for Contiki projects to have code examples.

Basically, the driver APIs are defined in ti-lib.h which you can find it under contiki\cpu\cc26xx-cc13xx.

Hi,

I want to develop an specialized wireless stack based on IEEE 802.15.4 phy layer. I reviewed the rfc files in cc26xxware_2_21_03_15980 but believe it does not cover all the parts. Are there any more fundamental drivers or sample codes that I can take as reference? (TIMAC is too miscellaneous to understanding, and I do not need the IEEE 802.15.4 mac layer).

Thanks,
John

TIMAC is already a compact implementation of 802.15.4.

0 John_Markie over 10 years ago in reply to YiKai Chen

Yes, TIMAC is a complete implementation of 802.15.4, especially the whole mac layer and APIs for applications. But these are not what we wanted, since:

1) We do not use TIRTOS and the OSAL based on it;

2) We do not want to implement a 802.15.4 mac layer, that's most the parts of TIMAC source codes;

3) We only need some RTOS-free drivers for CC26xx RF core, like rfc.h/c in cc26xxware (Infact, rfc.h/c are just the files we wanted, but I found they are too simple to cover all interfaces and commands fro RF core).

Thanks,

John
