extern type in 'C' and PUBLIC type in asm mismatch

What happens when you try this?

extern code unsigned char FONT1 [];

same problem... I've tried several different types in the 'C' code.

thanks!

Is there any problem with "FONT1" being a module name, a segment name, and an address name all at the same time?

I just tried the following simple program and it works great.

FONT1.A51

NAME	FONT1

?CO?FONT1            SEGMENT CODE
	PUBLIC	FONT1

	RSEG  ?CO?FONT1
FONT1:
	DB  'K' ,'e' ,'i' ,'l' ,' ' ,'S' ,'o' ,'f' ,'t' ,'w'
	DB  'a' ,'r' ,'e' ,000H

	END

#include <reg51.h>
#include <stdio.h>

extern unsigned char code font1[];

void main (void)
{
    SCON  = 0x50;   /* SCON: mode 1, 8-bit UART, enable rcvr      */
    TMOD |= 0x20;   /* TMOD: timer 1, mode 2, 8-bit reload        */
    TH1   = 221;    /* TH1:  reload value for 1200 baud @ 16MHz   */
    TR1   = 1;      /* TR1:  timer 1 run                          */
    TI    = 1;      /* TI:   set TI to send first char of UART    */

while (1)
  {
  printf ("%s\n", font1);
  }
}

Jon,

The only real difference I see in what you have and what I have is the position of the "code" keyword in the 'C' extern statement.

I'm not at work right now, so I can't check it out...do you think this is my problem?

thanks a bunch!

SO...

It turns out that the issue had to do with a bad install of either or both the Keil SW and the Cygnal IDE. I reinstalled both and now its all happy.

thanks,

The only real difference I see in what you have and what I have is the position of the "code" keyword in the 'C' extern statement.

The postition of the code keyword is all important.

In this case:

extern code unsigned char *FONT1;

extern unsigned char code font1[];
