Does anyone know of any good tutorials for programming with C on the TI-89 that is very comprehensive? Not so much for the C syntax but more for the assembly references to do things like clear the screen, etc.

| Techno Plaza has a pretty good one I'm zooming through right now (at least when I have the time). If you've done any programming, it should be pretty simple to understand. |

Thanks for the link.
Trying this code for a first sample but it will not compile with TIGCC because of the stdout and the stdin:
Code:
#include <tigcclib.h>
#include <stdio.h>
#include <string.h>
int main()
{
clrscr ();
char text[20];
fputs("enter some text: ", stdout);
fflush(stdout);
if ( fgets(text, sizeof text, stdin) != NULL )
{
char *newline = strchr(text, '\n'); /* search for newline character */
if ( newline != NULL )
{
*newline = '\0'; /* overwrite trailing newline */
}
printf("text = \"%s\"\n", text);
}
return 0;
ngetchx();
}
Is the 89 limited to what it can do with C? Or why can it not use all it's features? Or am I missing something? |

Okay, remember that this calculator doesn't have a command line, so [font="Courier New"]stdin and [font="Courier New"]stdout aren't going to work.
Where are you trying to put or draw the text?
I'm sorry I don't have an alternative solution, I'm just starting out learning C.
EDIT: Oh, and I would recommend using the newer version of TIGCC: GCC4TI.

| Thanks for the newer version. I'll check that out. After further reading after my post I found out that it was for the command line and why it wouldn't work. The text with printf() will put text on the home screen I believe and DrawStr is for the graph screen. I need to read up on the TI-89 specific functions for programming with C. |
