here is my code..is it correct.if wrong plz help me to generate pulse of 10khz .
#include <LPC21xx.H>
void T0isr(void)__irq;
void delay(void) { VPBDIV = 0x00000002; //Set pclk to 30 Mhz PINSEL0 = 0x00000020; //Enable pin 0.2 as capture channel0 T0PR = 0x0000001E; //Load prescaler for 1 Msec tick T0TCR = 0x00000002; //Reset counter and prescaler T0CCR = 0x00000005; //Capture on rising edge of channel0 T0TCR = 0x00000001; //enable timer
VICVectAddr4 = (unsigned)T0isr; //Set the timer ISR vector address VICVectCntl4 = 0x00000024; //Set channel VICIntEnable = 0x00000010; //Enable the interrupt } int main(void) { IODIR0=0X000000001;
while(1) { IOSET0=0X00000001; delay(); IOCLR0=0X00000001; delay();
} }
void T0isr (void)__irq { //static int value; //value = T0CR0; // read the capture value T0IR |= 0x00000001; //Clear match 0 interrupt VICVectAddr = 0x00000000; //Dummy write to signal end of interrupt
}
