Hello,

I'm busy with a robot project as a hobby and using a sonar ranger module (I2C) and some infra red distance detectors from sharp .
In order to define my system tick with timer 2 i would like to know what the average time is for each function that i use. especially for the AD convertion (sharp )and the I2C routines (sonar).

I tried to use the performance analyzer in keil but this function is not accesable for the 8051F120 from silabs (both through the menu or through the command window).
The uvision drivers from silabs are installed and the debugger is configured to use this drivers.


If i try other programs with a generic driver for a 8052 than the PA can be used.

Can anybody tell me how to use the performance analyzer with the F120 ?

Thanks on advance for the reply's.
