Posted on November 08, 2007 at 12:35Hello,
I’m really desperate with my first program with AMR.
Trying to set up the timer2 to do a simple interrupt every certain time, it doesn’t work.
My code is:
************************* MAIN CODE ****************************
int main()
{
debug();
GPIO_Config (GPIO1, 0x0100, GPIO_OUT_PP); //Led
GPIO_BitWrite(GPIO1, 8,0);
/*********** TIMER ****************/
TIM_Init(TIM2
TIM_PrescalerConfig(TIM2,0x0000 );
TIM_ClockSourceConfig(TIM2, TIM_INTERNAL);
TIM_ITConfig(TIM2, TIM_TO_IT, ENABLE);
TIM_CounterConfig(TIM2, TIM_START);
/************ EIC ******************/
EIC_IRQChannelConfig(T2TIMI_IRQChannel, ENABLE);
EIC_IRQChannelPriorityConfig(T2TIMI_IRQChannel, 10);
EIC_IRQConfig(ENABLE);
while (1)
{;}
}
******************** INTERRUPT CODE 71x_IT.c *****************
void T2TIMI_IRQHandler(void)
{
GPIO_BitWrite(GPIO1, 8,0);
GPIO_BitWrite(GPIO1, 8,1);
}
The program never goes to the interrupt routine. Why?? I don’t understand.
The compilation doesn’t report any error but simply not works.
Do I have to ''link'' the archive 71x_IT.C to project in any special form?
Software: IAR Workbench 5.0 Quickstar (already tested on EV 4.0 and 5.0 and quickstar 4.4 versions)
My hardware is: IAR quickstart Kit STR711 SK/IAR
I’d appreciate your help very much. Note that this is my first program.
Thanks

P.D. Comparing with another examples interrupts I see that grup “startup� in not in my program. What is this?
