Hi all,

My need is to have two GPIO pins to interface with external module from lpc43xx and I am not any proper signal to mux them in for 2 GPIO pins. I prefer not to use LEDS via I2C interface nor switches. I was hoping for couple reserved pins which can muxed in and configured as GPIO. Have anyone done this similar work on LPC43XX ?

Thanks

Jim

Problem is fixed. However, found one more issue with GPIO codes. The current LPC43XX code does not define LPC_GPIOINT. why ??

I think you are looking for LPC_SCU->PINTSEL0 which is defined in the latest version.
