i've been trying to implement a Timer1 interrupt, but when i activate the interrupt the USB port have problems, can anyone helpme?
The problem ocurr in the USBTasks() function when the timer1 goes off, and the interrupt is activate
void UserInit(void)
{
.....
T1CON = 0b01000100;
PIR1bits.TMR1IF = 0; // Clear flag
TMR1H = TIMER1H_VAL;
TMR1L = TIMER1L_VAL; // Reinit timer value;
T1Cont=0;
PORTDbits.RD4=1;
INTCONbits.GIE=0;
INTCONbits.PEIE=1;
PIE1bits.TMR1IE=1; //Habilito interrupcion Timer1
T1CONbits.TMR1ON=1;
PIE2=0x00;
.....}
-------------------------------------------------------------------------------------
#pragma code _HIGH_INTERRUPT_VECTOR = 0x000808
void _high_ISR (void)
{
ProcessTMR1();
_asm retfie 0 _endasm;
}
--------------------------------------------------------------------------------------
void ProcessTMR1(void)
{
if(PIR1bits.TMR1IF == 1)
{
PIR1bits.TMR1IF = 0; // Clear flag
TMR1H = TIMER1H_VAL;
TMR1L = TIMER1L_VAL; // Reinit timer value;
T1Cont++;
if(T1Cont==Posicion){
LATDbits.LATD4=0;
//PORTDbits.RD4=0;
}
if(T1Cont>=400){
TMR1H = TIMER1H_VA1;
TMR1L = TIMER1L_VA1; // Reinit timer value;
}
if(T1Cont==404){
T1Cont =0;
LATDbits.LATD4=1;
//PORTDbits.RD4=1;
mLED_3_Toggle();
TMR1H = TIMER1H_VAL;
TMR1L = TIMER1L_VAL;
}
}
}//end ProcessTMR1
