Hi, I'm a new user :). I'm now coding for wiz using libcastor and openwiz toolchain but I've some problems. How can I use opengl?(I don't need a tutorial on opengl function, i need to know how to set up it)
Second, how can I read the touchscreen coords? With GP2X F200 I used this code, but it doesn't work with Wiz:
CODE
typedef struct {

uint16_t pressure;

uint16_t x;

uint16_t y;

uint16_t pad;

struct timeval stamp;

} TS_EVENT;



struct Stylus{

int x, y, pressure, calibX, calibY, NewPress, Held, Released;

}Stylus;

void CalibTouch(){

int fd = open( "/dev/touchscreen/wm97xx", O_RDONLY | O_NOCTTY );

TS_EVENT ts_event;

do{

read(fd, &ts_event, sizeof(TS_EVENT));

}while(ts_event.pressure!=0);

Stylus.calibX = ((ts_event.x-200)*320/3750)/4;

Stylus.calibY = (((ts_event.y-200)*240/3750))/4;

Stylus.x = 160;

Stylus.y = 120;

close(fd);

}



void UpdateStylus(){

int fd = open( "/dev/touchscreen/wm97xx", O_RDONLY | O_NOCTTY );

TS_EVENT ts_event;

read(fd, &ts_event, sizeof(TS_EVENT));

Stylus.NewPress = 0;

if(ts_event.pressure>0){

Stylus.x = ((ts_event.x-200)*320/3750)-Stylus.calibX;

Stylus.y = (240 - ((ts_event.y-200)*240/3750))-Stylus.calibY;

if(Stylus.Held==0){

Stylus.NewPress = 1;

Stylus.Held = 1;

}

}else{

Stylus.Held = 0;

}

Stylus.pressure = ts_event.pressure;

close(fd);

}

How can I resolve?

Thanks :)
