task utilization and computational time

Post by stefano » Wed Nov 05, 2008 5:33 pm

Hi everybody,

I\'m using the Flex board with Erika.
I need to know the computational time and the utilization of all tasks used, so I ask you if there is in Erika something to get it, I mean something similar to JET in Shark?

Waiting a response, thanks!

Hi,

there is currently nothing like that in EE... sorry :-(

3 options:
- we can implement a feature like that, (the best place to implement it is probably into the EDF Kernel, which already has support for timers)

- if you are using BCC1, BCC2, ECC1, ECC2, then you can use PreTaskHook and PostTaskHook to have the hooks to take the timings. (you need to starta timer for that)

- As Simone did, you can use the second option, putting up and down a pin, and then use an oscilloscope...

Ciao,

PJ
