Field Documentation

keyCode

uint8_t cy_stc_key_event::keyCode

Key code.

This is the location in the keyscan matrix that is pressed/released. May be implemented as ((row * numCols) + col) or ((col * numRows) + row.

scanCycleFlag

uint8_t cy_stc_key_event::scanCycleFlag

Should be toggled for every scan cycle in which a new event is queued.

Use of this flag is optional. If used, it allows the consumer to determine whether an event is detected in the same scan cycle as the previous event or a different one. Note that this flag does not indicate any separation in time.
