Create/Define Touch Field

\i T A byte::field_idx byte::key

Parameter	Type	Range	Description
field_idx	byte	0 ... 63 (-1 = next free touch field index)	index of the touch field
key	byte	0 ... 255	value reported in case of touch event

Creates or redefines the touch field with index field_idx with the current values and properties previously set (e.g. Set Touch Field Width, Set Touch Field Make Macro, etc.) and also assigns key to the field.

The upper left position of the touch field is taken from the current cursor position.
field_idx may have the hex value 0xFF (decimal byte -1), in this case the controller will choose the next free (unassigned) touch field index.
Assigning a key value of 0 will inhibit the reporting of the make/break sequence to the application. The make/break macros however, if assigned, will still be executed.
Using an invalid field_idx or a value of 0xFF when all 64 touch fields are already defined causes a [NACK] to be sent by the iLCD Controller.
This command can even be used within a make or break macro to redefine the behavior of the current touch field to implement, for example, a toggle field behavior.
Using this command also sets the 'current touch field index' (see Set Current Touch Field Index), which can be used by Execute Touch Make Macro, Execute Touch Break Macro and Draw Touch Field Text Message.

Response:

[ACK]

Example

\iTA\xFF\x1

This will create a touch field with the next free index. If this touch field is pressed afterwards, K/k[01][ACK] will be reported via the active interface.
