The method void Chip_SYSCTL_SetPinInterrupt(uint32_t intno, uint8_t port, uint8_t pin) contains an error.

Through this error it wont configure PINs on Port 1 and 2 correctly.

The original version is:

void Chip_SYSCTL_SetPinInterrupt(uint32_t intno, uint8_t port, uint8_t pin) {
if (port == 0) {
/* Pins P0.1 to P0.23 only */
LPC_SYSCTL->PINTSEL[intno] = (uint32_t) pin;
} else {
/* P1.1 to P1.31 and P2.0 to P2.7 */
LPC_SYSCTL->PINTSEL[intno] = (uint32_t) ((port - 1) * 32 + pin);
}
}

The correct version is:

void Chip_SYSCTL_SetPinInterrupt(uint32_t intno, uint8_t port, uint8_t pin) {
if (port == 0) {
/* Pins P0.1 to P0.23 only */
LPC_SYSCTL->PINTSEL[intno] = (uint32_t) pin;
} else {
/* P1.1 to P1.31 and P2.0 to P2.7 */
LPC_SYSCTL->PINTSEL[intno] = (uint32_t) ((port - 1) * 32 + pin + 24);
}
}

Did cost me several hours because i trusted LPCOpen

(currently porting a project from CMSIS to LPCOpen)

I hope this fix will be included soon!

Thank you for letting us know of this problem. The fix as shown below will be available in the next release

1. Removed function Chip_SYSCTL_SetPinInterrupt from syscon_11u6x.c
2. Removed prototype for Chip_SYSCTL_SetPinInterrupt from syscon_11u6x.h
3. Added the STATIC INLINE version of Chip_SYSCTL_SetPinInterrupt API to syscon_11u6x.h as shown below


/* PIO0_0 [Offset: 0]; PIO1_0 [Offset: 24(0x18)]; PIO2_0 [Offset: 56(0x38)] */
#define PINTSEL_OFFSET "\0\x18\x38"

STATIC INLINE void Chip_SYSCTL_SetPinInterrupt(uint32_t intno, uint8_t port, uint8_t pin)
{
       LPC_SYSCTL->PINTSEL[intno] = (uint32_t) PINTSEL_OFFSET[port] + pin;
}
