LPC2478 arm7 core, after chip reset, the clock and power of timer 0 and timer 1 are turned on by default, but timer 2 and timer 3 are turned off by default, so there is no statement to turn on the clock and power in the program for initializing timer 0 and 1. Then I looked at some reference materials and found that the initialization of timer 2 and timer 3 was not given either. I was very curious about why the code that was not run dared to be sold as information (NXP LPC2478 development board CD information). So much nonsense, post the code, long memory.
//Init TIMER3 to measure PG inf
void Time3Init(void){
PINSEL5&=(~(3<<14));
PINSEL5|=(2<<14);//CAP3.1 P2.23
PCONP |= (1<<23);//Open TIME3 power and clock
T3CTCR = (1<<0) | (1<<2); //Config T3 as a Counter, counting on rising edge of CAP3.1 pin
T3TC=0; //reset T3
T3TCR=0; //Stop Counting
}
