[TIGCC] C strange 16x16 sprite error?

<< < (2/3) > >>

Liazon:
I forget how you typecast, but what's the point of typecasting data?

MathStuf:
I see a problem... You are not testing whether the strings are the same correctly. The right way is:
c1-->CODE ec1if(!strcmp(string_1, string_2))
{
// strings are the same
}
else
{
// strings are different
}c2ec2
That should help some. Turning on Grayscale would too.

In addition, you can't do arguments that way in C for the calcs. You need argv/argc and stuff like that (I'm not quite sure how to use them).

Good catch MathStuf!

I thought the main entry point always had to have the following signature (or prototype):

c1-->CODE ec1void _main(void)c2ec2

Can you pass parameters into _main? Do you have to do something special with the TIGCC startup code to actually pass the parameter into _main?

The standard main entry point for most computer based applications looks something like this:

c1-->CODE ec1main(int argc, char *argv[ ])c2ec2

 - argc : this is the number of strings that the argv array contains.
 - argv : this is an array of strings.

Of course you can :)
The functions neccessary to do this kind of stuff can be found in the header http://tigcc.ticalc.org/doc/args.html

TIGCC also offers an example program:
c1-->CODE ec1// An example of passing arguments to C program
// Try this program calling argtest(arg1,arg2,...)

#define USE_TI89
#define USE_TI92PLUS
#define USE_V200

#define MIN_AMS 100

#include
#include

#include

void _main(void)
{
 

Ranman:
Thanks for that example Saubue! :D I did not know that. :oops:

You're never too old to learn something new.  ;)

However, the example does show that you don't pass the data directly into _main via parameters; rather that _main must go get the data from some location maintained by the AMS through the use of specialized functions.
