**ts\_test\_mt** is used to test **tslib** using **ts\_read\_mt()** , see ts\_read\_mt (3). It can be used for single and multi touch devices and lets you test the input behaviour with tslib's filters applied. Two modes are offered by buttons on the display:

In **Drag** mode, one crosshair for each concurrently made touch contact is drawn to the framebuffer display.

In **Draw** mode, lines are drawed for each touch contact.

- **-r, --rotate \[value\]**

  Rotate the screen. value is 0 for 0 degree, 1 for 90 degrees (CW), 2 for 180 degrees (upside down) and 3 for 270 degrees (CCW).

- **-v, --verbose**

  Print the input samples' values to the console.

- **-j, --slots**

  Override the number of concurrent touch contacts to allocate.

- **-i, --idev**

  Explicitly choose the original input event device for tslib to use. Default: the environment variable **TSLIB\_TSDEVICE**'s value.

- **-n, --samples**

  Automatically exit after having read n samples.

- **-a, --altcross**

  Show an alternative crosshair symbol at the touch points.
