Hi Yong,

You need to perform initialization steps for the Timer Module before you can start the module.

Also send across your code, if possible. I will try and see what is the mistake you are committing.

BTW, you needn't enable the clock. The clock is enabled through the Software only.

HTH,

Ganesh

HI, ganesh

Do i have to enable clock as well when using TIMER_getCount()? If i enable it, the same error message (invalid CIO command) comes out.

Thank you

Yong

Hi, Ganesh

My code in main()

Uint32 start, stop;
CSL_cfgInit(); //initialization function generated by CDB
TIMER_start(hTimer1);
start = TIMER_getCount(hTimer1);

.....//other code

stop = TIMER_getCount(hTimer1);
printf("start: %d\n", start);
printf("stop: %d\n", stop);
printf("cycles: %d\n", stop - start);

in videocfg_c.c generated by CDB file

void CSL_cfgInit()
{
hTimer1 = TIMER_open(TIMER_DEV1, TIMER_OPEN_RESET);
TIMER_config(hTimer1, &timerCfg0);
}

thanks

Hi Yong,

Did you set the configuration parameters for the module properly ? Are you using the correct CSL for the chip ?

Have you set the parameters of timercfg0 correctly ?

Perform a reset timer before you config your timer i.e. TIMER_config.

Also one more important thing is that you need to multiply the difference by 8 i.e. any output from the TIMER module is scaled down by 8. You are missing the multiplication by 8.

Kindly verify the same.

Thanks and Regards,

Ganesh

Hi, Ganesh

I use default configuration parameters for the module , see below

timerCfg0

INput Clock Source(CLKSRC) External Source

Cl;ock/Pulse Mode(CP) Pulse mode

Pulse Width (PWID) one clock cycle

Function of TOUT(FUNC) General_Purse Output

DAta Oputput(TOUT pin) 0

TOUT Inverter Control(INVOUT) Uninverted

TINP Inverter Control(INVINP) Uninverted

Timer Operation &n bsp; & nbsp; Hold

Period Value ; 0x0

Counter Value ; 0x0

Control REgister(CTL) &nbs p; 0x0

Period Register(PRD) &nbs p; 0x0

Counter REgister(CNT) &nbs p; 0x0

Timer_Device1

Open Timer Device ; True

Handle &n bsp; & nbsp; hTimer1

Enable Pre-INitailization True

Pre-INitailize with & nbsp; TimerCfg0

Thanks
