触摸屏测试程序怎么编写

怎么看设备文件的路径,比如#define DEVICENAME "/dev/touchpanel/indev"为什么我没这个路径

#include <stdio.h>

typedef struct {
unsigned short pressure;
unsigned short x;
unsigned short y;
unsigned short pad;
} TS_EVENT;

static TS_EVENT ts_event;
static int ts;

int main()
{
ts = open ("/dev/ts", 0);
if (ts < 0) {
fprintf (stderr, "2410: Can not open touch screen!\n");
return 0;
}
