RTOS/CC1350: Computing elapsed time after an operation

Majd Mansour

Part Number: CC1350

Tool/software: TI-RTOS

Hello,

Could someone explain how to compute the time between operation 1 and operation 5, supposing we have 5 operations for example ( like reading from sensor sending data .. etc)

is there a function which gives the number of clock ticks , so that i can subtract the number of clock ticks in operation1 from the clock ticks in operation 5 (and then convert it to millisecond) ?

how would it look like in code for CC1350 sensortag.

Thanks a lot in advance

Hello Majd,

You can use the ClockP_getSystemTicks() API.

RETURNS
time in clock ticks
DETAILS
The value returned will wrap back to zero after it reaches the max value that can be stored in 32 bits.

More information can be found on the TIRTOS API located in your SDK documentation.

AB

Thanks AB,

is there any other way without using TIRTOS ? is it necessary to use TIRTOS to get systems ticks ?

Thanks

Hello Majd,

You can also try and read the SysTick Register (STCVR). See section 2.7.4.5 of the technical reference manual. www.ti.com/.../swcu117h.pdf
