CCS/LAUNCHXL-CC1312R1: Sensor controller compb problem

Part Number: LAUNCHXL-CC1312R1

Tool/software: Code Composer Studio

Hi,

I use simplelink_cc13x2_26x2_sdk_2_40_00_81 and CCS Version: 8.3.0.00009, Chip E version

I try to add compb task in sensor controller. but not working.

I want to alert M4 when the input voltages on DIO27 larger than about 2.6v.

I expect there is a message output from uart but fail...(NodeTask.c Line:247)

Please help to check if anything I miss within the code.

Thank you.

Hi Chris,

I'm nor sure I understand on which side you are seeing the issue. Have you verified the Sensor Controller (SC)code using the Sensor Controller Studio debug tools, are you sure it works as you expect?

Does the SC work but you are not getting the interrupt as expected?

Hi M-W,

Thanks for your reply.

I checked task testing and found that event handler code triggered normally when I change the voltage on DIO27.

I expect the event handler code call fwGenAlertInterrupt(); then the SceAdc.c, Line 95, taskAlertCallback(void) will be called then call compb_eventCallback(pOutput->outValue); so that it will Event_post(nodeEventHandle, NODE_EVENT_COMPB_STATE_CHANGE); then Display_printf(hDisplaySerial, 0, 0, "compb: %d\n", compb_state); but not function....

Hi Chris,

Have you tried using fwGenQuickAlertInterrupt() instead and see if it makes a difference? fwGenAlertInterrupt() will only take affect when the task code fully completes. The quick alert takes affect right away.

Also, in your TI-RTOS code, there is no pin conflict or anything like that in DIO27?

Hi M-W,
Thanks for your reply.
I just found that I missed to add the compb task id to scifStartTasksNbl();
Now the fwGenAlertInterrupt(); works well with compb task.
Thanks.
