[FONT=Arial]Hi all,[/FONT]
[FONT=Arial][/FONT]
[FONT=Arial]i working with a LPCXpresso Board 1769 and in the usermanual in found that al Ports 0.x and 2.x can creat interrupts and for exampel in the [SIZE=3][COLOR=#005042][SIZE=3][COLOR=#005042][SIZE=3][COLOR=#005042][COLOR=black]IO0IntEnR[/COLOR][COLOR=black]Register i can choose the ports for rising edge interrupt. But my problem is there are no Interrupt Handler for this Ports.[/COLOR][/COLOR][/SIZE][/COLOR][/SIZE][/COLOR][/SIZE][/FONT]
[FONT=Arial][SIZE=3][COLOR=#005042][SIZE=3][COLOR=#005042][SIZE=3][COLOR=#005042][COLOR=#000000]Do somebody know how to use this interrupts and do i have to write my own Interrupt handler ( i dont know how!)?[/COLOR][/COLOR][/SIZE][/COLOR][/SIZE][/COLOR][/SIZE][/FONT]
[FONT=Arial]There are only Interrupt handler for the EINT0-EINT3 but that are only 4 and not all 0.x and 2.x Ports[/FONT]
[FONT=Arial][/FONT]
[FONT=Arial]best regards [/FONT]

Yes, all (enabled) GPIO interrupts trigger EINT3 :)
