LAUNCHXL-CC1352P: Setting priority of sensor controller interrupt

Raphael Fischer1

Part Number: LAUNCHXL-CC1352P
Other Parts Discussed in Thread: SYSCONFIG

Dear TI-Team,

I wrote an application where I use the taskAlertCallback of the sensor controller. Is there a way to set the priority of this interrupt (like if is possible for other interrupt sources in the sysconfig)?

Kind regards and thank you for the help already!

Hi Raphael,

I believe you can set the interrupt priority in scif_osal_tirtos.c by modifying the osalRegisterTaskAlertInt function. In there, the interrupt is configured using default parameters, but you can modify the interrupt priority after the call to Hwi_Params_init.

Regards,
Michael

Thank you, it works!

However, you need to left-shift the priority by 5, so for a priority of 6 (the second lowest) you must write a 0xC0.
