Operating Mode
The operating mode specifies the conditions under which the controller
sends the X/Y touch coordinates (input data packet) to the host system.
Mode Stream is the default operating mode for the MT3000 controller. In
Mode Stream, the controller sends a continuous stream of data packets
when the screen is touched. The controller sends the data as long as a touch
continues on the sensor.
Because Mode Stream sends touch data continually, it is the most versatile
mode, and it provides the best response time and overall feel.
MicroTouch recommends that the touchscreen generate an interrupt as each
byte in the data stream arrives. Because touchdown and liftoff events are
specially coded, your software always knows exactly what the user is doing,
provided that the interrupts are sent as recommended. This enables instant
feedback and prevents data loss.
