Hi all,
I am using LPC2103,I had configured timer2[16 bit] and i had set it for MR0 match interrupt and reset the TC on match ,
It is working for the first time ,But second time it is not working [it is not going to the ISR routine]. I had configure to reset the interrut[IR] register in ISR.
Could some body help me regarding this.Is their any other addtional configuration which i need to do for continous interrupt?
i am working on simulation,
Thans in advance,Looking forward for replys.
Shanid
thank you shameel,
i got it ,I just enabled the interrupt after configuring the interrupt .
thank alot for your help, Thanks Shanid +91-8214003008
Here is the working code ,In ISR i have wrote one more line for writing an dummy to VECT.
/**************************************************
Test APP- Timer 2[Code which has worked ]
****************************************************/ #include<LPC2103.h> void ISR(void); int main(void) { int x=0;
T2PR = 0x00000005; //Load prescaler T2TCR = 0x00000002; //Reset counter and prescaler T2MCR = 0x00000003; //match reset the counter and generate an interrupt T2MR0 = 0x00000010; //cycle time T2TCR = 0x00000001; //enable timer
VICVectAddr4 = (unsigned)ISR; //Set the timer ISR vector address VICVectCntl4 = 0x0000003A; //Set channel control
VICIntEnable |= 0x04000000; //Enable the TIMER2 interrupt
while(1)
{ x=x+1; //Keeps loop running in single step }
}
void ISR (void) __irq {
T2IR = 0x00000001; //Clear match 0 interrupt VICVectAddr = 0x00000000; //Dummy write to signal end of interrupt
thanks
