Help running C program in 8051 emulator.

Greetings everyone,

I'm new to programming, and I'm having trouble running a c program in
an 8051 emulator.  I'm using emu51.exe (http://sourceforge.net/
projects/emu51/) with asm51.exe (http://www.metaice.com/ASM51/
ASM51.htm).  When I use asm51 to convert the c program to a HEX file,
I receive the following message:



C:\UHCL\CPROGR~1\asm51>asm51.exe

8051 Cross-Assembler, Version 1.2k

     (c) Copyright 1984-1996 by MetaLink

     Source file drive and name [.ASM]:

1\P08-15.c     Second pass

     ASSEMBLY COMPLETE, 30 ERRORS FOUND



Although the HEX and LST files are created, they don't appear to load
into the emu51.exe emulator.  I assume it is due to the errors I'm
receiving during "assembly" in asm51.exe.  Below is the source that I
am using.  If you could help me out with this, I would certainly
appreciate an email!

#include <stdio.h>

#define MAX_ROWS  5
#define MAX_COLS  4


void fillArray (int table[][MAX_COLS], int numRows);

int main (void)
{

	int row;
	int col;
	int	ary[MAX_ROWS][MAX_COLS];


	fillArray(ary, MAX_ROWS);
	printf("Data: \n");
	for (row = 0; row < 5; row++)
        {
         for (col = 0; col < 4; col++)
              printf("%8d", ary [row][col]);
         printf("\n");
        }
	return 0;
}


void fillArray (int table[][MAX_COLS], int numRows)
{

	for (int row = 0; row < numRows; row++)
	   {
	    table [row][0] = row * 10;
	    for (int col = 1; col < MAX_COLS; col++)
	        table [row][col] = table [row][col - 1] + 1;
	   }
	return;
}

Best regards,


Mark

Use an assembler on assembly code and a C compiler on C code.

SDCC is a free compiler.

So you ran a C file thru an assembler !?!?!

Where did you get the idea you can do that ??

I think you are in the wrong line of work !!

That is a simulator. An emulator in this context is hardware. See "ICE"

You don't mention which C compiler you are using to convert the C source 
you have into assembler.....

You have 30 errors in the source code. You need to fix the source and 
have NO ERRORS before you try and run it in the simulator.

I would suggest you download the Keil eval compiler/simulator and use 
that to test the code as the Keil 8051 tools are probably the best in 
the world.

Then from a solid and confirmed start point you can use the sourceforge 
simulator when the code is too big for the Keil eval sim.

However as it is only a very small amount of C he is better off using 
the Keil eval system.   That will be a LOT more reliable and robust. It 
also had a good set of manuals and a LOT more support.

Besides the simulator in the Keil system will be a lot better than 
anything else he can find
