tslib测试触摸屏的一小段程序

 

#include <stdio.h>
#include <stdlib.h>
#include "tslib.h"

#define DEV_NAME "/dev/event1"

int getTsXY()
{
    struct tsdev *ts;
    struct ts_sample sample;
    int ret;
    ts = ts_open(DEV_NAME, 0);
    if(!ts)
    {
        perror("Open error!\n");
        exit(1);
    }
    if(ts_config(ts))
    {
        perror("ts_config\n");
        exit(1);
    }
    while(1)
    {
        ret = ts_read(ts , &sample, 1);
        if (ret < 0)
        {
            perror("ts_read");
            exit(1);
        }
        printf("x = %d\ty = %d\t press = %u\n",sample.x,sample.y,sample.pressure);
    }
    ts_close(ts);
    return 0;
}
int main(int argc,char **argv)
{
    getTsXY();
    return 0;
}

在arm11上的触摸屏设备是dev下面的event1。在宿主机上交叉编译后移植到目标机执行。
