OMAPL138 LCDK interrupt timer2

Other Parts Discussed in Thread: OMAPL138

Hello, OMAPL138 experts, I am a student and develop on the OMAPL138 lcdk board (Connection to Computer is a Blackhawk USB560 v2 System Trace).
I just started to develope (NO SYS BIOS) on the OMAPL138. So I tried everything out like UART(send text to the console -Putty- to the Computer)
or when i press the user button3 the LED turns off...

Now I tried to do something with interrupts I want to use the Timer2 set a flag and in the main() I do something if the flag is set...
I tried the examples from the OMAPL138_StarterWare_1_10_04_01 and quickStartOMAPL1x_rCSL but nothing works. (I'm sitting here now 2 weeks and nothing works.)

Now to my Question. Is there an step by step example what i have to do for an ISR (Set Clock, Set TimerFlag(IFR)...)?

Regards,

Fernando

Hi Fernando richu,

Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages. Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics.

According to me, the timer example given as a part of OMAPL138_StarterWare_1_10_04_01 is one of the best examples which should straight away work for you on OMAPL138 LCDK.

After you install the starterware package, you will find the CCS project files of timer example at path: "..\ti\OMAPL138_StarterWare_1_10_04_01\build\armv5\cgt_ccs\omapl138\lcdkOMAPL138\timer"

A step by step procedure of importing and running starterware examples is given at the below link.
