} // _InterruptVector The function name _T1Interrupt is not an accidental choice. It is actually the predefined identifier for the Timer1 interrupt as found in the Interrupt Vectors Table of the PIC24 (defined in the datasheet), and as coded in the linker script, the .gld file loaded fo...
static const intc_vector vector_table[4] = { __intc_irq_vector_4_0, __intc_irq_vector_4_1, __intc_irq_vector_4_2, __intc_irq_vector_4_3, }; This allows the linker and compiler to fully optimize the interrupts from vector to handler. Step 5: Defining direct IRQ handlers (vect...
// Timer A interrupt service routine #pragma vector=TIMER0_A1_VECTOR __interrupt void Timer_A1_ISR( void ) { _DINT(); int den1, den2, rem1, quot, dummy; den1=100; den2=10; switch(__even_in_range(TA0IV, TA0IV_TAIFG))
The following example illustrates the syntax that could be used to associate a function to the Timer1 interrupt vector: void __attribute__ ((interrupt)) _T1Interrupt (void) { // interrupt service routine code here… } // _InterruptVector ...
