A89: how to draw lines and stuff with TI-GCC
how am l supposed to use the library functions in graphlib.h with TI-GCC? l
don't understand how l'm supposed to do something like fill(0,0,30,30,2) (in
the graphlib.h file) with this program. l can #define it at the top of my
source code, and put fill(0,0,30,30,2); in my program but it doesn't do
anything. Am l supposed to somehow switch to a graph mode or something? And
also what is the point of void clr_scr(); in the source code? And also one
more thing, where is the DrawStr command (in the source code) listed?
#include <romcalls.h> // include file for rom calls
#define clr_scr graphlib__0005
#define idle_loop userlib__0000
void idle_loop(); // prototype for idle_loop();
void clr_scr(); // prototype for clr_scr();
int _ti89,_ti92plus; // compile for both calcs
void _main() // entry point
{
clr_scr(); // clears the screen
DrawStr(0,0,"Hello, World",4); // displays '"Hello, World" at x=0, y=0
idle_loop(); // waits for a key press
}
