LP-EM-CC1354P10: LF Crystal Tuning

Part Number: LP-EM-CC1354P10
Other Parts Discussed in Thread: CC1354P10

Hello,

I am using simplelink_cc13xx_cc26xx_sdk_7_10_01_24 release and I am trying to output the 32Khz clock signal on an I/O pin to tune LF crystal. I Didn't find anything in SysCFG tool to configure the I/O for this.

Please share the reference code for CC1354P10 which will work with the SDK without any issues.

Thanks,

Santosh

Santosh,

Ryan B provided the following helper links in addition to what we communicated on offline via email:

The Low Power RF Team may have further input in the AM.

I am not finding AONIOC32kHzOutputEnable() in 1354P10_6 sdk I have installed.

Hi Santosh,

AONIOC32kHzOutputEnable() is found in the following file: C:\ti\simplelink_cc13xx_cc26xx_sdk_7_10_01_24\source\ti\devices\cc13x4_cc26x4\driverlib\aon_ioc.h.

Cheers,

Marie

Please share the full snippet how you did this in the 1354 SDK.

Thanks,

From Ryan offline, this is the only additional code required:

#include <ti/devices/cc13x4_cc26x4/driverlib/aon_ioc.h>

#include <ti/devices/cc13x4_cc26x4/driverlib/ioc.h>

/…

IOCPortConfigureSet(IOID_12,IOC_PORT_AON_CLK32K,IOC_STD_OUTPUT);

AONIOC32kHzOutputEnable();

From which you would use your own desired IO pin instead of IOID_12. Please test this out and update the E2E thread accordingly.

Regards,

Chris

P.S. This is closed now, thank you all !
