How do I configure a timer using Processor expert

I have added the timer interrupt TI1:TimerInt, but all of the timer setup functions are greyed out. All I have available are Enable, Disable, EnableEvent and DisableEvent. How do I configure the timer using Processor Expert?

Hi Julian,

you have to specify the timer peripheral and the period in the properties, e.g.

For TimerUnit_LDD for example see Tutorial: Timer (LED) with Processor Expert for Kinetis | MCU on Eclipse

I hope this helps,

Erich

Thanks for the help, if it was that simple... FYI I am using C/W 10.7 with a S08SH8. In Components I have TI1:TimerInt loaded from Processor Expert, where there is NOTHING like Timer Unit_LDD. In the Components Library/Properties mine is essentially the same as yours, except Periodic interrupt Source is MTIMmod and Counter is MTIM. Interrupt S Period is Unassigned and when I click on it it refers to the Timing Dialogue Box. - plenty of information about it, but nothing about how to access it. All I want is a periodic interrupt; surely it can't be all that difficult???? BTW in processor expert there are no components with names ending in _LDD. To use a metaphor - The C/W published information explains in great detail the theory of the internal combustion engine, but not how to drive the car.

Hi Julian,

As you did not specify which device you are using, I (wrongly) assumed you are using an ARM Cortex :-(.

For the S08 (using S08QE128 below) it is basically on the top level the same: specify the timer/interrupt source and period:

This then will call the TI1_OnInterrupt() event for every timer interrupt:

The function/hook is generated into Events.c:

I hope this helps,

Erich

Thanks for your help. The last time I used this architecture was with the Motorola MEKD1 and MEKD2 kits in the '70s.

I am now able to compile without errors and so I can continue on my rather steep re-learning curve.

hwo this will work in main().

please give me an example to generate delay to toggle LED
