Error in LPC23xx.h

Victor Sanchez

I think that there is an error in the LPC23xx.h include file that apperars in the KEIL web site:

RealView MDK 3.10 -> Supported Devices -> LPC2378 -> Header Files

The lines:

/* FIOs can be accessed through WORD, HALF-WORD or BYTE. */
#define FIO0DIR0 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x01))
#define FIO1DIR0 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x21))
#define FIO2DIR0 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x41))
#define FIO3DIR0 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x61))
#define FIO4DIR0 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x81))

#define FIO0DIR1 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x02))
#define FIO1DIR1 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x22))
#define FIO2DIR1 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x42))
#define FIO3DIR1 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x62))
#define FIO4DIR1 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x82))

#define FIO0DIR2 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x03))
#define FIO1DIR2 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x23))
#define FIO2DIR2 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x43))
#define FIO3DIR2 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x63))
#define FIO4DIR2 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x83))

#define FIO0DIR3 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x04))
#define FIO1DIR3 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x24))
#define FIO2DIR3 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x44))
#define FIO3DIR3 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x64))
#define FIO4DIR3 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x84))

must be:

/* FIOs can be accessed through WORD, HALF-WORD or BYTE. */
#define FIO0DIR0 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x00))
#define FIO1DIR0 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x20))
#define FIO2DIR0 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x40))
#define FIO3DIR0 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x60))
#define FIO4DIR0 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x80))

#define FIO0DIR1 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x01))
#define FIO1DIR1 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x21))
#define FIO2DIR1 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x41))
#define FIO3DIR1 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x61))
#define FIO4DIR1 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x81))

#define FIO0DIR2 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x02))
#define FIO1DIR2 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x22))
#define FIO2DIR2 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x42))
#define FIO3DIR2 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x62))
#define FIO4DIR2 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x82))

#define FIO0DIR3 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x03))
#define FIO1DIR3 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x23))
#define FIO2DIR3 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x43))
#define FIO3DIR3 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x63))
#define FIO4DIR3 (*(volatile unsigned char *)(FIO_BASE_ADDR + 0x83))

Best regards.

    I have uploaded now a new version of the file - so the issue is corrected.

    Thank you for pointing it out.

    Note that the MDK Version 3.11 contains already a corrected header file version. I strongly recommed to use the current version of the toolchain (since also some other issues with LPC23xx devices are corrected there).
