./ts_calibrate error: ts_open: no such file or directory
I have a problem with mini2440. the touchscreen does not work when my application (the Qt application I mean) runs on it.
this is my output for "printenv" in mini2440:
[root@FriendlyARM bin]# ./ts_calibrate
ts_open: No such file or directory
[root@FriendlyARM bin]# printenv

TSLIB_CALIBFILE=/etc/pointercal
and in this directory: / dev / input => I just have two files: enevt0 and mouse
in ts.conf: uncomment the first line.
I don't know what ts_open is. where is it? or why show me this error?

ts_open tries to open a file stored in a variable TSLIB_TSDEVICE
.
TSLIB_TSDEVICE
must be a device to open readable sensor inputs. In your case, it should be /dev/input/event0
.
Then ts_calibrate reads the first line in ts.conf
to get module_raw xxx
. Make sure your plugin folder (/ usr / local / tslib / lib / ts) contains the plugin you are uploading module_raw
.
