how to use timer 1 interrupts in cc2530 ?

To generate PWM on CC2530, you can refer to sunmaysky.blogspot.tw/.../how-to-output-pwm-from-cc2530.html.

I checked your post sir, but I have already initialised that part for timer 1.

Also, I dont want the port pins to be configured for timer output. I configure them as gpio, and I seperately set or reset them after getting interrupt several times.

Do you have a dead while loop in your ISR?

No, I am not using a while loop, but I am setting a flag to load timer continuously upto a certain value. That does work like a loop. Here's what I wrote:

HAL_ISR_FUNCTION(T1_ISR, T1_VECTOR)
{
IRCON = ~BV(2); //clear interrupt
T1STAT = 0; // clear interrupt
HalLcdWriteString("ISR", HAL_LCD_LINE_2);

if (close_flag)//channel 1 interrupt
{
close_flag = 0;
Timer1Ch1_Function(); //call function to load timer again
}
if (open_flag)
{
open_flag = 0;
Timer1Ch0_Function();
}
}



static void Timer1Ch0_Function(void)
{
unsigned char buf[5] = "";

_itoa(timer, buf, 10);

HalLcdWriteString((char*)buf, HAL_LCD_LINE_2);

if (timer > 0)
{
open_flag = 1;
timer--;

T1CC0H = 0x00;
T1CC0L = 0xFF; // load compare value

T1CNTH = 0x00;
T1CNTL = 0x00; //start timer

}
else
{
open_flag = 0;
T1CTL &= ~(0x03); // disable timer
//P1SEL &= ~(0x4); // P1.2 as gpio
P1 &= ~(0x4); // clear P1.2
}

}

It seems that you will make ISR comes very fast and it looks like it stuck there. Can you elaborate what you intend to do?

I am writing the timer to get a delay of around a mili second. I am writing a value (say 10,000) in the variable "timer". Now I want that timer to run 10,000 times so I can give a delay (a pulse) of around 10 seconds to the curtain motor.

I had previously used polling method to check timer count value (using while loop). But I was always receiving a failure response for all commands in that method.

So now I am doing it with interrupt.

Yes, exactly, that is what I wish to do. I am sorry if I wasn't clear before.

For running PWM, I set and reset the gpio pin after timer value expires.

for running that 10s (this value can be anything) timer, I had written that code I had posted above. I wanted step size 1ms.

You had said that there shouldn't be a dead while loop in the ISR. Can you tell me what goes wrong in that case?
I did'nt put any loop in the ISR, but I had a loop in the callback function previously.

Using your code, the ISR would be trigger every 1 ms and it is similar to there is a while loop in ISR.

So, how should I exit from there?

You cannot if you use your code. That's why I suggest you to use my PWM example to start PWM signal and also start a timer event which is scheduled to be executed 10 seconds later to stop PWM.

But the time duration is variable. Can I use that for variable time duration?

I traced further, my code gets stuck in the else loop in the code I posted, not in the ISR.
