Hi everyone,
as usual I'm confused and not able to find solution on web or datasheet.
I'm using the TWR-KV58F220M with KDS 3.0 and Processor Expert.
I just want to create one interrupt at 1000Hz.
When I look tutorial like this:
http://mcuoneclipse.com/2012/08/13/tutorial-timer-led-with-processor-expert-for-kinetis/
They use the component Timer, but on my project I didn't have any Timer component. What should I use?
I got the component InterruptManager but it's empty in the Inspector:
Second question what should I use if I want to use timers in my code? (like start a timer, do something, stop timer and see how long my code was)
Third question, how can I know that my TWR-KV58F220M is running at 220Mhz? where we can change the frequency
Last question, when I do calculation with float, the floating point unit is directly used in the processor?
Thank you for all these answers.

Hello alex,
- You can use the component of "fsl_pit" or "fsl_ftm"
- After you configure the fls_pit or fsl_ftm component, you will find the Methods that
using the timer:
- About the chip clock , please refer to the Reference Manual -> Figure 6-1. Clocking diagram , you can refer to the section to
configure the related register to change the frequency of your chip.
And if you want check the real frequency of the chip , you can check from the PTC3 pin :
from the register of SIM_SOPT2-> CLKOUTSEL to select the clock to output on thePTC3pin , about the detail
you can check the introduce of this register.
Hope it helps
Have a great day,
Alice Yang
