So it also keeps telling me OUTPUT and HIGH aren’t found.
using this to produce the disassembly code:
avr-gcc -mmcu=atmega328p -Wall -Os -o heart.elf heart.c_

So it also keeps telling me OUTPUT and HIGH aren't found.

Well, they are not defined in avr/io.h, either.

Which Arduino? Which version of the IDE? Why do you think you need to include avr/io.h?

#3

I'm programming an uno. The .ino code had that. I'm trying to convert it to C then to assembly to write back onto the arduino. How should I go about making the pins outputs? I could set HIGH to 1.

It seems to me that by the time you are ready to undertake this that you are able to determine what include files you need, if any, and to understand the build process (including the ability to set verbose mode and look at the intermediate files produced).

How should I go about making the pins outputs?

In an ino file, a C file, or in assembler?

#5

This won’t do what you think it will:

  for ( i = 0; i < 8; i++)
   {
      pinMode(rowPins, OUTPUT); // make all the LED pins outputs
      pinMode(columnPins, OUTPUT);
      digitalWrite(columnPins, HIGH); // disconnect column pins from Ground
    }

Try instead:

  for ( i = 0; i < 8; i++)
   {
      pinMode(rowPins[i], OUTPUT); // make all the LED pins outputs
      pinMode(columnPins[i], OUTPUT);
      digitalWrite(columnPins[i], HIGH); // disconnect column pins from Ground
    }

Maybe that’s the cause of your errors.

Maybe that's the cause of your errors.

It is the cause of the italics though (the [i] has been removed)

@jlach9: Please edit your post, select the code, and put it between [code] … [/code] tags.

You can do that by hitting the “Code” icon above the posting area. It is the first icon, with the symbol: </>

It's not C right now, I gather?

#10

Use code tag for pasting your codes.

Which version of IDE you are using, i have already tested code in adruino v 1.6.4 later version.
i have made small changes also.
