In the portISR.c file of the port for the LPC23xx microcontrollers (SourceportableGCCARM7_LPC23xxportISR.c) there is the following line FIO2SET |= (1<<0); I think that this has been used in the development of the port but must be deleted to avoid interference in an application that use the pin P2.0. Best regards, Victor
Thanks for pointing this oversight out. I have removed it from the next release. Regards.
