Other Parts Discussed in Thread: TMS320F28027
Hi,
I am using Xint1, Xint2, Xint3 in my project with TMS320F28027. Xint1 & Xint2 are working without any problem, whereas Xint3 is not working. All interrupts are initialized the same way. Please help me to find out where I made the mistake.
In main program below three instructions are written.
InitXint3();
PIE_registerPieIntHandler(myPie, PIE_GroupNumber_12, PIE_SubGroupNumber_1, (intVec_t)&xint3_isr);
CPU_enableInt(myCpu, CPU_IntNumber_12);
Initialization is done as below.
void InitXint3()
{
PIE_enableInt(myPie, PIE_GroupNumber_12, PIE_InterruptSource_XINT_3);
GPIO_setQualification(myGpio, GPIO_Number_5, GPIO_Qual_ASync);
GPIO_setExtInt(myGpio, GPIO_Number_5, CPU_ExtIntNumber_3);
PIE_setExtIntPolarity(myPie, CPU_ExtIntNumber_3, PIE_ExtIntPolarity_RisingEdge);
PIE_enableExtInt(myPie, CPU_ExtIntNumber_3);
}
Interrupt subroutine is written as below.
interrupt void xint3_isr(void)
{
if (d==0)
{
GPIO_setHigh(myGpio, GPIO_Number_6);
d=1;
}
else if (d==1)
{
GPIO_setLow(myGpio, GPIO_Number_6);
d=0;
}
// Acknowledge this interrupt to get more from group 12
PIE_clearInt(myPie, PIE_GroupNumber_12);
}

Mahesh K.R.
