Hi,
I execute the following lines of code and
expect me that the program will deliver a 1Hz
pulse train on PIN RA2. the problem is that
I only get 6 pulses from RA2 (LED). I Send you
an image of the simulation. Can you see anything
wrong?
Thank you!
Code:#include <pic.h> #include <htc.h> void Initialization (); __CONFIG(FOSC_LP & WDTE_ON & PWRTE_OFF & CP_OFF); #define _XTAL_FREQ 32768 #define LED RA2 int S = 0; void main() { Initialization (); while (1) { if (S) { S=0; LED = 1; __delay_us (1); LED = 0; } } } void Initialization(void) { TRISA = 0b00000000; TRISB = 0b00000001; OPTION_REG = 0b00000100; INTCON = 0b10100000; TMR0 = 0; LED = 0; } void interrupt tc_int(void) { if (T0IF) { T0IE = 0; S = S+1; T0IF = 0; T0IE = 1; TMR0 = 0; } }
