Touch Controllers Reference Guide40
Finger Only
Syntax: <SOH>FO<CR>
Description: Sets the mode of operation of a TouchPen controller to accept only
finger input. The TouchPen controller ignores pen input.
There are three modes available:
Finger Only mode detects finger contact only and processes finger
coordinate data.
Pen Only mode detects pen contact only and processes pen
coordinate data.
Pen or Finger mode detects pen and finger contact, giving priority
to pen contact when both are detected. Pen or Finger mode is the
default mode for TouchPen controllers.
The pen mode changes back to the default setting at power-up, or if
you issue a Restore Defaults command. You can use the Set
Parameter Block command to change the default setting.
Choose the appropriate mode for your application. For example,
applications requiring only signature input use Pen Only mode.
Gaming applications typically use Finger Only mode, and point-of-
sales applications that require signature verification may use Pen or
Finger mode.
Additionally, changing the pen mode setting can optimize the
performance of the touchscreen. In Pen or Finger mode, the
TouchPen controller checks for input from both a pen and a finger.
The controller always gives priority to the pen. If you are not
currently using the pen for your touch application, use Finger Only
mode for optimum performance.
Response: <SOH>0<CR> Positive response.
