Hello,
I am unable to configure my F28379D to generate ISR at rising edge of GPIO23, please review code snippets below, thanks:
CPU01_main.c
/* GPIO23 Interrupt from Altera */ GPIO_setDirectionMode(23 ,GPIO_DIR_MODE_IN); GPIO_setQualificationMode(23, GPIO_QUAL_SYNC); GPIO_setMasterCore(23, GPIO_CORE_CPU2);
CPU02_main.c
/*
* Configure ALTERA(FPGA) to DSP interrupt line
*/
void AlteraInerruptCfg()
{
/* Enable X-INT interrupt in the PIE: Group 1 interrupt 4 */
Interrupt_enable(INT_XINT1);
/* Set Interrupt GPIO */
GPIO_setInterruptPin(23, GPIO_INT_XINT1);
/* Edge type interrupt */
GPIO_setInterruptType(GPIO_INT_XINT1, GPIO_INT_TYPE_RISING_EDGE);
/* Enable XINT1 */
GPIO_enableInterrupt(GPIO_INT_XINT1);
}
my cfg file:
/* ================ Hwi configuration ================ */
//var Hwi = xdc.useModule('ti.sysbios.hal.Hwi');
var c28Hwi = xdc.useModule('ti.sysbios.family.c28.Hwi');
/*
* Create Hwi instances for PIE.
*
* Using the mappings found in the table "PIE MUXed Peripheral Interrupt Vector
* Table" (found in the SYS/BIOS API Documentation), the following mappings for
* interrupt number can be found:
*
* PIE group 1, interrupt 4 -> interrupt number 35 -> XINT1 interrupt
*
*
* Both PIE interrupts are also configured to run the interrupt service routine
* 'myIsr()' when triggered.
*/
/* PIE group 1, interrupt 4 */
var interruptNum = 35;
var hwiParams = new c28Hwi.Params();
hwiParams.arg = interruptNum;
hwiParams.enableAck = true;
hwiParams.maskSetting = c28Hwi.MaskingOption_BITMASK;
hwiParams.disableMask = 0x0;
hwiParams.restoreMask = 0x0;
c28Hwi.create(interruptNum, "&xint1_isr", hwiParams);
