State-of-the art software components
delivered in the form of a firmware library are
combined with the MWCT1012 hardware.
All wireless charging solutions consist of
both production hardware and software.
The wireless charging software is optimized
firmware, providing all of the necessary
functions of a wireless charging transmit
controller. The firmware consists of four main
blocks necessary to implement wireless
charging: the protocol state machine, the
communications decoding block, timer
functions, and the foreign object detection
algorithm. Freescale provides access to
these core software blocks via an API that
provides maximum control to the application
developer.
