现在在调试SSD2533的10点触摸屏，使用 TouchTest APK测试，上报坐标是准确的，在画线的时候，要释放手指后，线条才显示出来。
在画线时候，后台是一直都在打印上报的数据的。
if ((touch_status>>4)&(0x3ff)) //at lease one finger detced
{
for (i = 0; i < MAX_FINGERS ;i ++)
{
if((touch_status>>4)&(1<<i))

tp_ssd2533_read_reg(0x7C+i,val,4);
mt_buf[i].x = val[0]|((val[2]&0xF0)<<4);
mt_buf[i].y= val[1]|((val[2]&0x0F)<<;
mt_buf[i].press=(val[3]&0xF0)>>4;
