creating timers statically with SYS/BIOS

Other Parts Discussed in Thread: SYSBIOS

hi all,

i am trying to use timers in a SYS/BIOS program. I created statically a timer using XGconf, i configured it's properties, but i cannot obtain it's handler to use the instruction:

Timer_start( handler);   in my source code.

Normally, the handler is the returned object from the function  Timer.create(.......) . here is a part of my cfg script:

var instti_sysbios_hal_Timer0Params0 = new ti_sysbios_hal_Timer.Params();
instti_sysbios_hal_Timer0Params0.instance.name = "myTimer";
instti_sysbios_hal_Timer0Params0.startMode = xdc.module("ti.sysbios.interfaces.ITimer").StartMode_USER;
instti_sysbios_hal_Timer0Params0.period = 400000000;
instti_sysbios_hal_Timer0Params0.periodType = xdc.module("ti.sysbios.interfaces.ITimer").PeriodType_COUNTS;
Program.global.myTimer = ti_sysbios_hal_Timer.create(1, "&myTick", instti_sysbios_hal_Timer0Params0);

i tried 'myTimer' as an argument for Timer_start(), but the program does not recognize it.

so what is the handler of a timer created statically?

    I will ask to have your question moved to the Embedded Software->BIOS forum. BIOS-related software questions will find the best sources of answers there, while device- and hardware-based questions will find the best sources of answers in the C6000 forums.

    In the future, it will help to identify the device and the version of SYS/BIOS and the version of CCS that you are using.

    Mohammed,

    What do you mean by "does not recognize it"?  Is your application not compiling?  Could you try inserting the following header file into your application?

    #include <xdc/cfg/global.h>

    This will result in a configuration-specific generated header file being included, which in turn contains extern declarations of your config-time created 'handles'.

    The runtime code Timer_start(myTimer); looks right to me.

    thanx Shreyas,

    I meant by "does not recognize it" that the compiler classified it as a undefined symbol, and the compilation failed.

    Adding  the "#include <xdc/cfg/global.h>" statement in my source code solved the problem.

    thanks again

    regards.
